#sumobot

In a team of 4, we manufactured a Sumobot that competed against our peers. We used a LiDAR, UltraSonic, and 2 IR sensors, and an Arduino board to make it fully autonomous.  Our Sumobot won the competition, proving to be durable and fast.

We began design stages virtually, with CAD and electronic ideas. Together we decided components and principles we wanted to use. Our chassis had a very small clearance with the ground, attempting to inhibit a competitor to flip us/gain an advantage by being underneath us. We used the largest size dimensions and centered our weight close to ground; big and heavy but not top heavy - harder to flip. The use of castor wheels assisted our bot in spontaneously changing direction. We wanted our bot to be as smart as possible so we used 3 different sensors. This did make coding more challenging and time consuming with calibrations and debugging. We created two slots for the back wall and lid for easy access to the electronics. The lid printed too large, without enough time we made a duct tape lid which was not efficient.

Future improvements: more secure mounting of sensors, more organized wiring, a 3D printed lid. All of these improvements amount to more time allocated for manufacturing.
