Description:

This is our 2nd generation base ATR kit fit up with OmniWheels. As pictured it has double row omni-wheels, but you can also purchase it with single row omni wheels. It is an extremely rugged well built robot. The wheels are axle mounted and are supported using sealed ball bearings. The motors are very powerful. The base is made of aluminum which makes it easy to drill mounting holes for your electronics. The kit provides you with what you need to make a great Omni-Wheel robot.

This robot is ideal for indoor and light duty outdoor activity. The ATRs steer using skid steering (differential steering). By varying the speed or direction of the wheels will allow the robot to turn. With high traction ATR tires this is difficult because the tires have to skid. Using the Omni tires allows easy turns because the wheels allow side slip. This kit should only be used on level ground. While the robot is plenty powerful to climb hills straight on, if the robot is sideways to a hill, it will side slip down the hill. We have loaded these robots up with over 100 lbs and it turned and drove very well. See our general ATR page for videos.

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. The middle wheel is 1/16" lower than the front and back to allow easer pivoting with the ATRs, with the omni wheels this will cause a little rocking if you make this 6WD. 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. With the double omniwheels the total width is about 19.25" by 18.75" long and 4" high (the wheel height). The clearance is a little over an inch.

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.

For full details and descriptions of the ATR and all the items, see our ATR Robot Building Page . Additionally, you can see our general ATR page for videos of the ATR robot in action.

When you purchase this kit you will get access to our assembly manual that contains color images and step by step instructions, or you can opt for us to assemble it for you.

This kit does not include a microcontroller, sensors, or RC unit. See our ATR Robot Building Page for options and links to our controllers, sensors, and controller batteries. Don't forget to get your battery chargers either.
