adding realistic car controls. This isn’t difficult. It involves removing
the circuit and potentiometers from the radio transmitter control
and making a mock-up steering wheel for one potentiometer and a
foot pedal throttle control for the other potentiometer.
Improving the telepresence system
Golem I is a basic telepresence system that can be improved upon
with a little thought. Improvements will add cost to the system.
However, these subsystem improvements can be added over a time.
Stereo-vision
Implementing high-fidelity stereo-vision on the Golem I is a worth-
while endeavor. There are great benefits to be derived from this
experimentation, namely, depth perception. This is still an area
