MQP 1 - Ship Recycling Robot

The dangerous process of dismantling large ship hulls often involves cutting down and recycling the ship’s infrastructure. According to US OSHA standards, ship breaking operations expose workers to a wide range of hazards or conditions likely to cause injury or illness. This project aims to improve worker safety in the ship-breaking industry by showcasing the potential for automation of the metal cutting process. We designed a computer vision system and torch attachment to work in tandem with the Franka Emika Panda arm. Furthermore, we implemented a test bed to quantify the parameters of the cutting process. Our resulting prototype displays the viability of a robotic approach to ship recycling.

MQP 2 - SCREAM 3.0: Super-elastic Continuum Robot for Endoscopic Articulation and Manipulation

Laryngeal tumors are common, yet challenging to treat endoscopically due to the lack of articulation in commercially available surgical instruments. Teaming up with a physician at Brigham and Women’s Hospital, we designed and constructed an integrated device with a needle-sized, steerable laser sheath to make formerly untreatable tumors accessible and operable.

The objective of this project is to investigate building an at-scale continuum robot to enhance a physician’s dexterity in minimally invasive endoscopic surgery. We present the design and construction of a continuum robotic manipulator and actuation unit consisting of a notched tube capable of providing three degrees of freedom: rotation, translation, and distal tip bending. The system encompasses a steerable wrist, control panel, and actuation module that directly integrates with the endoscopic handle currently being used by physicians.

MQP 3 - Optically Driven Robots

Robotic systems are playing an ever-increasing role in everyday activities from work life to home life. As a result of this increasing role, many researchers have begun to explore new ways to actuate these robotic systems to allow them to work within specific environments and help lower total power consumption. Today, robotic systems are actuated utilizing traditional systems such as motors and servos; however, this project explores new ways to actuate and control robotic systems utilizing carbon nanotubes (CNTs). CNTs provide a new and innovated construction to robotic systems eliminating the need for traditional metallic components due to their actuation based upon the presence and absence of a concentrated light source.

MQP 4 - M.A.R.I.A. (Multi-Agent Robotic Intelligent Assembly)

Construction can be optimized by using robotic workers to create structures from smart materials. The prior creation of a construction agent, a robotic inchworm, laid the groundwork for our team to focus on the development of smart building blocks which utilize visual light communication(VLC) and a decentralized planning algorithm. Using a decentralized algorithm allows each agent to act independently with simple rules, creating emergent behavior to build a desired structure using the structure itself as the primary organizer of construction.

MQP 5 - Robotic Waste Sorting V2

The U.S. recycling industry depends on material recovery facilities to process materials collected through single stream recycling. A growing global population and recently imposed higher material purity standards require more efficient waste-sorting methods. This project contributes to research on automated solutions to this problem. A modular cartesian robot with a closed-loop linkage arm and 3-pronged gripper was designed and built to assist in sorting cardboard. Additionally, a conveyor belt for testing was designed and built, and a preliminary machine vision program to detect cardboard was developed. This work provides a basis for further research and development of waste sorting technologies.

MQP 6 - Vineyard Robot

The purpose of this project was to create a prototype of an automated pest deterrence system for Wachusett Vineyards. The following report details how birds can greatly affect a vineyard’s crop yields, how robots are used to solve agricultural problems, and how we planned and designed a cyber-physical system to deter birds from the grape crops. We used a Raspberry Pi and camera to run motion detection software and automatically scare away these birds via predatory audio. We also created a desktop application to monitor the live stream footage, manually activate the sound deterrence, and view information about previously captured motion detections.

MQP 7 - swARm

Methods of robotic swarm control are becoming increasingly prevalent in academic literature. Recent approaches have studied how augmented reality applications can facilitate control of robotic swarms. However, studies suggest that robotic swarm systems can overload the operator due to the large number of moving parts. Therefore, we developed a novel multi-user augmented reality application, deployed on the Magic Leap One, allowing operators to distribute responsibilities among each other when controlling robotic swarms in an immersive and intuitive way. Furthermore, by creating a modular architecture, new methods of multi-user swarm control can be introduced and evaluated quickly.

MQP 8 - Flexible Robotic Origami Gripper (FROG)

Origami robots have been introduced as a new soft robotic technology that can be easily constructed from planar sheets of material to create rigid or deformable linkages. With this Major Qualifying Project, the team investigated the capabilities of a modular soft robotic gripper with triangular beam and Yoshimura origami finger designs folded from PET plastic. Due to its origami design, the gripper is lightweight, flexible, and durable. A vision system working in conjunction with an impedance controller aided the gripper to determine and provide three stable grasp patterns to pick up an assortment of objects. The implementation of a switching control system has demonstrated the need for more adaptive control for this compliant gripper. This project provides a foundation for future research into origami grippers.

MQP 9 - Interactive Bio-Inspired Dino

The goal of this MQP was to design, fabricate, and implement an interactive robot model of the head and neck of a Deinonychus that creates the impression of a living dinosaur. The neck contains 6 actuated degrees of freedom and is composed of custom-made vertebrae. The vertebral column is modeled as a continuum arm and controlled by a network of Arduinos. The project makes use of Popovic Lab’s Hydro Muscles, which are elastic linear actuators that replicate muscular motion. These Hydro Muscles are powered by a custom closed-loop hydraulic system and control the dinosaur neck by pulling on wire ‘tendons’ that are attached to key points on the neck. The team focused on elements that mimicked anatomical structures in order to develop a system to mimic lifelike behavior. The dinosaur is capable of neck and jaw movements, and continuous random eye motion. Future work will focus on developing sensor-based intractability.

MQP 10 - Variable Impedance Actuators: Robotic Drumming Applications

The goal of this project was to create a robotic drumming system which could play a variety of percussive instruments, produce basic and complex strikes, and demonstrate aural and visual expressivity. To accomplish this a robotic arm was designed to approximate a human arm, with a variable impedance actuator (VIA) utilized at the wrist. The VIA can be tuned to simulate the dynamics of a drum roll. Due to circumstances resulting from the COVID-19 pandemic, thee team produced simulations to verify the design of the robot. Despite the arm being unable to fully reproduce the range of human playing ability, this simulation demonstrated the capability of the robotic arm to replicate, with moderate fidelity, the aural and visual characteristics of human players.

MQP 11 - AFIA – Aid for Investigating Accidents

In Ghana and other sub-Saharan countries access to robotics is extremely limited by the lack of materials and the cost of imports. The AFIA team developed a robot made mostly out of materials readily available in Ghana in the hopes that future designs like this can help make robotics more accessible. The robot is a multipurpose robotic platform designed to travel on poorly maintained dirt roads that are common in remote areas around the world and allows for the addition of sensors to fulfill the needs of the user. The goal of this project was to create an affordable, sustainable, multipurpose robotic mobile base to expand the availability of robotic technology.

MQP 13 - Demining Phase V

Every year at least 7,000 people around the world die from abandoned, unexploded landmines leftover from times of conflict. Current demining methods are expensive, dangerous, and slow. To combat this issue, our team is continuing the project to create an operational autonomous demining system. The system will consist of three parts: a rover, a drone, and a base station. The rover will be able to search a user defined area for unexploded landmines. When the rover finds a landmine, it will record the location. After the search is complete, the drone will then fly to the locations of the landmines and will drop a small payload onto the mines to detonate them. The base station acts as the communication link between the rover and the drone and provides a user interface for the operator to control the system. The goal of our project is to have a functioning, relatively inexpensive system that can increase the safety and efficiency of global humanitarian demining efforts.

MQP 16 - Autonomous Mural Painting Robot

On average, it takes a person about 40 hours to paint a full color, 10’x10’ mural. The process is time consuming and expensive, as you have to pay the artist for their time. High costs associated with murals make them unrealistic for most places. By automating the process of painting, we can drastically cut the cost of large scale, full color murals, making them more attainable for the average building. The goal for this project was to make a robot capable of painting an 8 color mural on a vertical wall, without human intervention. Our end product is able to decode any image and paint it in a given size.

MQP 17 - SLAM on the Atlas Robot

Simultaneous Localization and Mapping (SLAM) is a powerful method for autonomously exploring new environments, which has never been applied to humanoid robots. This project implemented SLAM on the Atlas humanoid robot, allowing it to interact with and explore novel environments. The Atlas robot was programmed to create 3 dimensional maps of environments and localize itself within them. Due to constraints in time and safety the project was conducted mostly in simulation. Both stereo cameras and LiDAR were used in experiments to identify the robot’s surroundings and avoid obstacles. These sensors paired with the robot’s locomotion allowed the Atlas robot to search and navigate unknown areas.

MQP 18 - Metamorphic Manufacturing

Metamorphic manufacturing is a type of digital fabrication wherein robotic systems are employed to incrementally deform material into a desired shape. This approach has the potential to greatly reduce material waste compared to subtractive methods such as CNC milling, and can achieve material properties superior to what is possible with additive methods like 3D printing. The aim of this project is to develop a prototype metamorphic manufacturing system capable of shaping plasticine clay. Utilizing the 6-axis ABB IRB 1600 robotic arm equipped with a custom end-effector and interchangeable tools, a system was constructed to achieve this objective. A LiDAR camera was employed to capture accurate 3D models of the plasticine workpiece as it is being shaped. Automated tool-changing was also implemented to allow for a fully-automatic workflow.

MQP 19 - Autonomous Drone Pollination

The declining bee population poses a threat to many aspects of life on earth as they are essential pollinators responsible for pollinating 80% of flowering plants. Our team aims to supplement the declining bee population with drones capable of pollinating flowers autonomously. The goal of this project is to create a system capable of locating sunflowers within a region and transferring pollen between them. The proposed solution consists of an off the shelf drone, a flight controller, an on-board processor, an actuated end-effector, and a camera. The team intends to incorporate all of these features together into one system capable of navigating a bounded region, detecting, and approaching sunflowers, and transferring pollen between them using the end effector.

MQP 20 - Multi-Modal Locomotion Robot

A variety of animals such as primates, dogs, and bears switch modes of locomotion between quadrupedalism and bipedalism to better complete certain tasks. However, very few robotic platforms can effectively combine the two forms of locomotion. A multi-modal robotic platform with such capabilities would provide additional adaptability in unstructured environments, broadening its potential applications. Therefore, we extended an existing quadrupedal platform with the capability to transition into a bipedal stance. In this project, we built a physical robot, developed an accompanying software stack with a reinforcement learning pipeline, implemented quadrupedal locomotion, and achieved bipedal standing in simulation. Our integrated hardware and software platform affords future roboticists the opportunity to test and develop more adaptable locomotion strategies and increase the functionality of robots more broadly.

MQP 21 - Lionfish Phase IV

Indigenous to the western Pacific, lionfish are an invasive species which have been wreaking havoc along the coasts of the western Atlantic. The rapid reproductive cycle of these fish combined with the fact that they have no natural predators in the Atlantic Ocean has made them a considerable threat to the local ecology. Current methods of combating the invasive lion fish have seen little to no results. This is the fourth year that students from WPI have collaborated to develop a robotic solution to help curb the exploding lionfish population. This year’s focus was on developing a stereo vision system capable of detecting an object and determining its distance, an improved navigation system which incorporates PID control, as well as a revised design for the harvesters' container.

MQP 22 - Needle Intervention System with Mirror Ultrasound Imaging

Procedures such as Percutaneous Nephrolithotomy (PCNL) often face problems with ineffective needle insertion due to the unknown geometric relationship with the needle, fascia, and ultrasound probe. The goal of the project is to develop a needle insertion device with mirror ultrasound imaging, which provides an intuitive and simple solution to guide the needle insertion path. This is achieved by visualizing the forward-view of the needle insertion by changing the relative angle between the mirror and US probe.

MQP 23 - NASA Lunabotics Competition

The NASA Robotic Mining Challenge is a yearly competition in which university teams build a rover to navigate rough terrain and mine and deliver simulated icy regolith. With strict size constraints, additional challenges are to minimize the rover mass, energy used, and communication bandwidth, as well as achieve full autonomy. Our MQP developed an original design for an all-new rover with a rocker-bogie chassis and a novel, two degree of freedom, backhoe-style excavator. We were only able to build and test the excavator portion of this robot due to COVID and time constraints. We also programmed and tested the state machine and navigation system, creating a code base that can be used by future teams.

MQP 24 - DigSafe Buried Cable Detection

Underground power cables must be marked by utility providers before any groundbreaking work can be performed on a work site. Currently, technicians mark cables by hand, and with seasonal fluctuations in the demand for the service technicians cannot always do so efficiently. This project aims to create an autonomous robot and supporting documentation to increase the efficiency of the cable marking process. The robot is intended to navigate a work site, detect buried cables, and accurately mark them in compliance with Massachusetts law.

MQP 28 - Autonomous Combat Robot

In a combat robotics match, two robots armed with high kinetic energy weapons attempt to damage, control, or otherwise disable their opponent. The majority of combat robots are glorified remote controlled cars, implementing little to no autonomous features. One of the most popular weight classes for combat robotics is the 3lb or beetle class. Due to the extreme environment and fast motion of combat competition, automated robots have the potential to out-perform human drivers. This MQP’s autonomous combat robot remains aggressive and deals damage to the opposing robot, which are important elements for success. It is sufficiently robust to survive repeated impacts and accelerations, while challenging human drivers.

MQP 31 - Partial Hand Prosthetic

The purpose of this MQP was to develop a partial hand prosthetic for a patient with an amputation at the metacarpophalangeal joint of the index finger and thumb. There are no commercially available prosthetics for this specific injury and so this MQP tackles this gap in prosthetic technology. The resulting solution consists of a two degree of freedom passively actuated index finger, one degree of freedom sensor driven thumb, solenoid locking system, and passive variable compression bladder. Both qualitative and quantitative testing has demonstrated that this device restores the pinching capabilities of the patient.
