4WD ATR Base Kit with 42mm motors

This is our 2nd generation base ATR kit. It is an extremely rugged well built robot. The wheels are axle mounted and are supported using sealed ball bearings. The motors allow this robot to climb walls. The base is made of aluminum that is easy to drill for mounting holes for your electronics. The kit provides you with what you need to make a great All-Terrain robot.

This is a rugged frame made of 1/8" thick aluminum to accept our IG42 gear motors. This is our 2nd generation ATR frame and wheel housing. We took our previous design that had separate motor housings that mounted to a base and made it all one piece. We also stretched it slightly, adding the ability to make it 6WD. The aluminum frame is fully gusseted adding greater rigidity. The aluminum is all laser cut for an exact fit-up and then hand welded and polished. Later if you want to make this robot 6WD, just add the middle set of wheels and motors. See our ATR page for more details.

The base is 14.25" wide x 17.25" long. The sides are 2.125" high (bottom edge to top surface). Note, these dimensions do not include weld filler, which adds a little to the overall dimensions. As configured it has a ground clearance of about 2 5/16". The width with the wheels is about 23" and the length is about 21.5". The overall height is just the wheel diameter of 6.75".

There are a lot of options and additions you can select, the links of all the items are included below. Follow the links for details of each item and option.
