Render of 15lb Combat Robot
I led the design and development of a 15lb overhead spinner combat robot. Similar to the TV show "BattleBots," the point of the robot is to compete against other robots of the same weight class and to disable the opponent. I spearheaded the project and primarily worked on the frame of the robot, integrating parts designed by my team and the electronic system. I worked with each member so the part they worked on was optimized for space usage and compatibility with the frame. One of the primary goals for our design was to optimize the height of the robot, as the overhead spinner had to be as low as possible to hit a wide variety of robots, which resulted in a total height of the robot being 2 inches.
I worked with the weapon lead to run FEA on the weapon to test the skeletonized structure, and I helped design the weight of the weapon to be at the edges to optimize moment of inertia, allowing the robot to generate 6000 J of kinetic energy. I communicated with the electronics lead to ensure that the mechanical hardware would be compatible with the motors, maximizing efficiency.

Finished 15lb Combat Robot
The main materials that were selected were AR500 steel and 6061 aluminum for their strength and weight, respectively. The robot was designed with manufacturability in mind, as it's made of plates that can be cut through one plane. Plates were drilled and tapped for screws to bind them together. By minimizing the complexity of the geometry, the cost of the bot went down significantly.
