Contact Robtronics for help.
1. Drive motor pulley loose.
1. Tighten motor pulley set screws.
2. Broken connection at motor connector.
2. Check blue/yellow wires and in line motor
connector at motor
3. Drive circuit not getting power.
3. Check drive motor fuses on fuse block (blue

4. Drive motor damaged.
4. Repair or replace motor.
One drive only does not operate.
Determine first if it is the drive motor or
drive circuit. To do this swap the wires
that go to the motors at white
connector. Same motor still not working
then motor is bad. Problem switches to
other motor, then problem is in main
box possibly the drive circuit itself.
5. Drive Circuit on main board problem.
5. Send main electronics box back to Service
Dept.

1. One motor pulley set screw loose.
1. Tighten set screws.
Robot not driving straight.
2. Straight drive adjustment needs to be
adjusted.
2.Find adjustment on the main circuit board. See
diagram of main board in Appendix.
Character Head Turning System
