Octobot9

Octobot9 is a table-top robot designed for testing mapping algorithms. It moves with two continuous Servos, three short range and two long range IR Sensors, has a gripper arm, and is controlled by a bluetooth enabled Arduino with a PC-based controller application. This robot was built by Jeremy Bridon.

= Construction =

The gripper arm was first build by using the company's assembly instructions. Then a Google SketchUp model was created. The materials used were metal tubing, custom metal pieces for the LCD frame, IR range finders, and the servo mounts. The main body was made with plexiglass.
