Figure 52 - Hills and rough terrain are no problem for the huge drive motors
The only time Goober could not cross an obstacle is when it was too tall to fit under the frame. Going down a curb was no problem, but Goober could not roll up a curb like his brother Oberon thanks to smaller diameter wheels and a frame in front of the tires. For the most part, any urban terrain was no problem for Goober and any place a power chair could go, so could the robot.

The two large gel batteries would run all day long on a single charge, so I had no need to replace the bank. To charge the batteries, I just plugged in the 24 volt charger at the end of the day and Goober was ready for another run the next day. I also added a few new functions that would allow me to shut down all visible lighting systems so that Goober could find a dark corner to just sit and hide at night, spying on the surrounding area using only night vision. This made for a very stealthy security mode.
