Chapter 7 Drive Motor System
CHAPTER 7
Drive Motor System
Your robot is provided with two high quality industrial grade drive motors. Each
motor controls a drive wheel-left and right. Steering of the robot is accomplished by varying
the speed and direction of these motors. For example, when the left motor runs faster than
the right, the robot turns to the right.
Each drive motor is connected to its drive wheel via pulleys and 1/2" wide rubber
timing belts. The pulley set screws and bolts should be kept tight.
Trouble-Shooting Drive
Perform the following steps first when trouble-shooting a drive problem:
1.
Do the other radio control functions operate?
Do the other RC features work
such as siren and tape? If they do not, check the fuses on the robot battery and
fuses on the main fuse block in the main electronics box. Especially look at the fuse
labeled 5 Volt Regulator Processor and 5 Volt Regulator Receiver (see the fuse
block detail in the Appendix).
2.
Check drive belts and motor pulley set screws.
Especially if you hear the motors
activate but the robot does not move.
3.
Check connections to motor controls and motor leads.
These are blue and
yellow wires coming from the electronics box and going to the drive motors. There is
a white connector in line. The joystick could be pushed in the on position while the
connector is being checked for an intermittent connection. If there is a bad
connection, the connector and/or pins should be replaced. While doing the test just
explained, have the robot wheels off the ground.
Perform the following depending on the symptoms indicated:
________________________________________________________________________
Note:
The best way to look at what the drive motors and wheels are doing is to put
something under the back of the robot to get the wheels off the ground. You will then be
able to see exactly what motor and wheel is working or not working, and in what direction.
________________________________________________________________________
Neither drive operates:
Check the fuse on the robot battery. One of the fuses supplies
power to the drive.
One drive only does not operate either direction:
Check the specific drive fuse on the
fuse block (left or right). See the fuse block detail to identify the correct fuse, or look for any
blown fuses. The fuse block is located in the main electronics box. If after replacing, the
fuse blows again, the
drive motor
or
drive circuit
could be causing the problem.

- If the drive motor is the problem, you would have likely heard the
motor grinding or scraping before the fuse blew. To test the motor for operation,
swap the motor wires. It is best to have the robot wheels off the ground when doing
