| Dobbybot in the hands of our skillful driver: Praga |
For a battlebot competition, we decided to build a bot under 30$. Clad in stainless steel plates for armour and a flipper arm powered by 12 kgcm servo motors, production cost was 32$.
The Design
I was responsible for structural design. I made multiple mechanical designs and finally used my 3-wedge sided, very low profile (7 cm high) version. The robot competed with other robots that cost 300$ and won the 3rd place. My wedged design with low center of gravity and almost zero ground clearance was commended for its uniqueness and novelty by the judging panel.

Making
We took the robot 100 km away from the university, to the hometown of Chinthana for welding. We got the stainless steel plate free from his relative.
