Arduino controlled robotic vehicle commands by Arduino Pro mini. The dimensions are roughly 90 x 60 x 60 mm (length x width x height). To detect obstacles, it features an ultrasonic sensor. Additionally, optical sensors can be attached to track a line. This design is geared towards experimenting and programming practice. A flanged ball bearing MF126ZZ (6x12x4 mm) secures the front wheel's vertical axis. The front wheel itself utilizes a 6x10x5mm ball bearing. Preventing wheel slip, an Oring of appropriate size is mounted on each wheel. Motors used are identical to those found at http://www.thingiverse.com/thing:686321. The wheels are affixed to the cross shaft using superglue for a secure hold.
