IG42-DB4, 4WD All Terrain Heavy Duty Robot Platform Assembly and Operation This is a Heavy Duty All-Terrain Robot platform with 42mm gear motors, built to navigate through rough terrain and over small obstructions. The wheels are chain driven and supported by two bearings, allowing it to support large payloads.

IG42-DB4, 4WD All Terrain Heavy Duty Robot Platform Mechanical Assembly 1. Start by mounting the motors as shown in the figure below, with the motor spacer plate between the motor and the chassis. Make sure to use Loctite on the screws. Once the motor is mounted, the small Dshaft sprockets can be mounted on the motor shaft. The hub should face the motor and they should be pushed all the way against the inside plate with just a small clearance for rotation. 2.

To do this, first make sure that the motor sprocket and the axle sprocket are lined up. It may help to loosen both set screws on the axle sprocket and power the motor so the sprocket spins on the axle but is free to move side to side. Once they are lined up, tighten one of the set screws and remove the other set screw.

Alternatively, clamp the chain in a vise and grind/file the ends of the pins down. Then drive the pin through the chain.

Reference source not found. and tension chain by s liding the motor away from the axle. The chain should be tight enough so there isn’t much slack but loose enough so that it isn’t adding extra strain on the motor shaft. Listen when running the robot to notice if there is an uneven sound coming from the motor. If so, the chain is probably too tight. 10. Repeat for the other four wheels.

Use foam tape on the bracket and underneath the battery to ensure a snug fit. 12. Measure a place on the chassis to mount the switch. Drill a ½” hole. The top of the chassis is a good place for it so that the terminals are protected underneath the chassis and the switch is protected from being accidentally turned off in a collision.

IG42-DB4, 4WD All Terrain Heavy Duty Robot Platform Operation 1. Before powering on the robot make sure it is up on blocks so the wheels can spin freely. Occasionally some or all of the wheels start as soon as the motor controller gets power. In this case the settings of the motor controller need to be changed. 2. Make sure to use the correct DIP switch settings. If using a Sabertooth motor controller in R/C mode switch 1 should be DOWN (closest to the number) and all other switches should be UP.
