NavBot 2.0

The NavBot 2.0 is my robot that I have created (and re-designed) for the Seattle Robotics Society's Robomagellan autonomous vehicle contest. The base is constructed of retracting seatbelt motor which are tied directly to low pressure drive wheels via custom axles I machined myself. The processor/controller is a Orangutan X2 made by Pololu. This comes with an LCD display making debugging MUCH simpler.


The "unique" looking rear wheel is from a ride-on PowerWheels kids toy. Although it seems out of place it allows the robot to pivot on one wheel without being thrown off by the "caster action" that smaller wheels would cause on soft terrain and grass. The drive motors provide plenty of torque and the direct drive approach made this robot the quietest by far of any of the robots at the competition!
