This is the new version of my Arduino based Robot prototype featured earlier. This version has a new slightly bigger chassis (12.8 mm diameter) for a lower profile and better space. Some very helpful guys at my university cut it out for me in Polycarbonate! It’s super strong :D

Look, pictures!

I’ve also attached a Sharp IR GP2Y0A21YK proximity sensor for very limited object avoidance. The plan is to mount it on a servo later so the robot can “turn its head” and better perceive its environment. I also have a few Optical Phototransistors which should come in handy :) Also, the 9V consumer battery is something I plan to replace at some point.

Acroname Robotics have a very helpful article on linearizing the output of the Sharp IR sensor.
