HoverBot Kit

Nearly frictionless, hovercraft make challenging robot platforms. Robots with wheels travel in the direction they are headed and stop when commanded. Hovercraft on the other hand coast and twist as they travel, requiring new ways of thinking and procedures for controlling them. This characteristic gives the NearSys HoverBot the ability to simulate a two-dimensional spacecraft and the issues involved with controlling it.
The HoverBot kit contains the parts to construct a robotic hovercraft, all you need to add is a robot controller. The HoverBot kit costs $85.00 plus $11.00 shipping (the larger box increases the cost of shipping this kit). A CheapBot-14 and CheapBot-18 works well as the robot controller and if purchased with a HoverBot kit, will be shipped at no extra charge.
