I'm working on the base of a Hover-Bot. It's in the design stages, so only the lift factor has been checked. I have two more ducted fans on order and they'll supply the propulsive force for the Hover-Bot. My goal is to create a two dimensional simulation of satellites.
In traditional robots, when the motors are shut off, the robot stops. Not so for a "nearly" frictionless sliding robot. To get the Hover-Bot to stop, it must apply reverse thrust to counteract the initial thrust that got it moving. There's also the issue of sliding sideways.
Currently I'm investigating the amount of current the lift fan draws based on the supply voltage.
I have a movie clip that I'll post shortly.
