TRAKR mod ideas #Ideas #Hacking #Hardware
possible trakr mods:
* Add a gyro for more accurate turning
* Add recharging capability for NiMH batteries
* Add proximity sensors
* Make the camera tilt controlled by a servo
* Modify the controls on the remote to be analog instead of on/off
* Add a wide-angle lens.
* use USB port on remote for computer control of the robot
* Make a recharging "base station" that the robot can drive into

the remote is powered up. It is hoped that this information will
be useful for reverse engineering the radio protocol being used.
