Building an Autonomous Hovercraft
     

A recent instructables
article provides step-by-step instructions on building an autonomous
or remote-control hovercraft. The chassis is made from insulation foam
covered with carbon fiber composite. A nylon skirt and a big brushless
DC motor provide the hover power. Two smaller Rimfire brushless motors
with variable pitch props provide thrust and steering. A PIC
microcontroller is used along with a XBee wireless communications module
for remote control. The robot also has ultrasonic range sensors. The
article includes video of the finished robot hover over a snowfield.
