Robotics at Maryland Yasiru Jayakody – Mechanical Engineering

[email protected] Science, Discovery and the Universe

Project Goals In the past, Robotics at Maryland has simply improved upon past robots. However, this year they are building a new robot from entirely from scratch. This means that all the mechanical and electrical components have to be designed and built anew, and the software and controls have to be rewritten. The advantage is that we can vastly improve our robot from the previous one by using newer, smaller, more efficient parts.

My Role I worked with the Mechanical Team and more specifically the battery hull sub-team. Our goal was to design and build waterproof hulls to house the batteries for the sub. The batteries are constrained in the hulls and can be charged without removing them from the hull. In order to this safely, we need an effective way to measure temperature as well as a failsafe in case of overheating. In order to constrain the batteries in the hulls, we decided to use H-shaped brackets. This shape would use the least amount of material and would allow us to just slide our batteries in. We are using bead thermistors to monitor the temperature inside the battery hulls and a pressure release valve as a failsafe.

Conclusions Working on this project has given me a lot of insight into the design process and the difficulty behind taking something from design concept to actual material product. In addition, I saw the amount of planning and logistics it takes to integrate different components of the same project.

Acknowledgements Thank you to the whole Robotics at Maryland organization for letting me work on this project with you. This is something now that I am looking to explore as a career path.

Intro For my capstone project, I worked with Robotics at Maryland to build an autonomous, underwater vehicle to compete in the International RoboSub Competition. The competition asks the robot to navigate an underwater obstacle course and complete simple mechanical tasks. Most of the planning and design was done at the Neutral Buoyancy Lab and the actual competition takes place in San Diego in July.
