Pioneer 2TM, 3TM manual Getting Inside, Removing the Nose

ActivMedia Robotics

Remove the small plastic plug which is near the hinge on the top plate and near the edge by the wheel. Under it, you will see the head of a large hex bolt. This bolt tightens (clockwise) or loosens (counter-clockwise) the drive belt for that side of the robot. Turn it using a 5mm hex key probably not more than 1 full rotation. Avoid over tightening.

Test to make sure that it is tight enough by holding the wheel while running the self test. When adjusted satisfactorily, re-tighten the screws on the side and replace the plug.

GETTING INSIDE

We normally discourage you from opening up your robot. However, on occasion, you may need to get inside, for instance to access the user power connections on the Motor- Power board and attach your custom electronics. Or you may need to get to your onboard computer and its accessories.

Open the robot AT YOUR OWN RISK, unless explicitly authorized by the factory.

REMOVE THE BATTERIES FIRST!

We describe here how to remove your robot’s nose to get at the onboard computer. And we describe how to access the contents of the body of your Pioneer 3 and 2 DX or AT robot.

Removing the Nose

The Pioneer 3- and 2-DX and –AT onboard computer sits just behind the robot’s nose. And you may have to remove the nose to access the front sonar array’s gain adjustment pot. Two screws hold the nose to the front sonar (or blank) array. The AT also has a screw at the bottom of the nose that attaches to the body; the DX’s nose is hinged at the bottom.

Figure 21. Remove indicated screws to access front plate of Pioneer 2- and 3-DX and -AT robots.

Remove all nose retaining screws with the 3mm hex wrench supplied with your robot. Unlike earlier Pioneer 2 models, you do not have to remove the Gripper or the front Bump Ring accessories.

Once loosened, the DX nose pivots down on a hinge. For the AT model, four pins along the nose’s back edges guide it onto the front of the robot. Simply pry the nose out and away from the body.
