This is our Heavy Duty ATR DB Chassis. It is an extremely rugged well built robot. It features chain driven axles, which are mounted with two sealed ball bearings which takes all of the weight off of the motors. Because of this it has the ability to drive and turn with very heavy loads. Look at our Main ATR support page and our DB ATR support page to learn more about the robot's size and capacity.
Each of the four axles are driven by a large and powerful IG42 Gear motor via a roller chain to yield a very smooth and slip free mode of operation. This robot is designed for loads greater than 25lbs. For loads greater than 40lbs you need to go with lower gear ratio motors and pneumatic tires. The biggest issue with weight is pivot turns on carpet and grass takes a great deal of torque to skid steer. See our ATR page for more details.
This is the chassis and hardware only, for the wheels, motors, etc. see our wheeled robot kits.
The ends of the shafts are exposed on the inside that allowing encoders to be used. Another option is to choose motors with encoders already on them.
There are slots in the side panels that allow easy assembly of the motor and chains and adjustment of the chain tension. The motors and transmission allow this robot to climb walls.
Features and Specifications:
- Dimensions: 12.25" x 16.25"
- Weight: 4.9lbs (just the chassis)
The frame is made of 1/8" thick aircraft grade aluminum. The design uses all laser cut parts with mortise and tenon design for precise alignment and mating of the parts. The chassis is completely welding using TIG and MIG. All the necessary motor mounting hardware, chains, sprockets, etc are provided as part of the chassis. The chains provide a 10:15 reduction motor to wheel shaft.
This item usually ships within 3-5 days depending on volume. Assembly adds a couple more days.
