IG42-SB2 2WD Tube Mount Robot Platform Assembly and Operation The IG42 2WD tube mount platform is a simple robot that can support high payloads. It consists of the 2WD robot chassis and provides all the necessary parts to turn the robot chassis into an operational robot. It supports our IG42 planetary gear motors.

IG42-SB2 2WD Tube Mount Robot Platform Mechanical Assembly 1. Start by mounting the motors to the motor plates using the provided M4 screws. Use Loctite to keep the screws from vibrating out. 2. Next mount the motor plate to the motor tube, again using Loctite or nyloc nuts. 3. Mount the motor tubes to the chassis plate using the provided #4-40 hardware.

The shaft collar inside the tube is used to mount the shaft to the motor. Make sure to use the longer set screw provided (1/4-20 x .375”) here and tighten it down through the hole in the side of the shaft and onto the flat part of the motor shaft.

Mount the caster to the caster plate with the provided hardware, then mount the caster plate to the chassis making sure to use the spacers as shown below. The configuration shown below is for the 6” wheels. If assembling with 10” wheels the spacers will go on the bottom of the chassis so the caster plate hangs below the chassis.

Use the battery bracket to mark the necessary mounting holes to be drilled (typically these will be 1/8” holes). Drill the holes in the chassis and mount the battery bracket using the included hardware and, if necessary, foam tape to ensure a tight fit. Also included in the battery bracket hardware kit are some plastic spacers.

Mark and drill holes (1/8” for motor controller, ½” for switch). Optionally, switch mounting brackets are available for purchase for easier switch mounting (see link below).

IG42-SB2 2WD Tube Mount Robot Platform Inflating the tires Before running the robot on the ground, make sure the tires have been inflated. Running the robot with a flat tire can cause the tube to spin inside of the tire and damage the valve stem. For this reason it is a good idea to check the tires periodically to make sure they are inflated.

The joystick is calibrated once a connection is made and will remember the position of the joystick as the center position. This will cause the robot to move erratically. 7. If the wheel aren’t moving as desired, it may be necessary to swap the Alieron and Elevator plugs or to reverse the channels on the transmitter. To reverse channels see the instructions for “Servo Reversing” in the Spektrum documentation. General Terms 1.
