Used in good working condition, has all of the parts, tested. Does move forward backward left/right and in circles with the help of r/c remote control. Connects to computer on windows-10 using a new downloaded version "Command Center Lite 1.0.7" from Robotica Website. Had rust on a couple of battery terminals of the robot and remote control due to busted battery cell; which is removed and cleaned. The system takes a total of 12 AA battery cells not included.
