Frame information
- drive base dimensions: 25" wide x 37" long
- Front is straight across
- Rear is 16" straight
- Both ends are chamfered 4.5" width x 5" length
- 6 wheel design with pneumatic tires, wheel spacing is 9.5" between wheels
- Wheel axles are 9 inches from each end
- Center wheel dropped 1/4 inch
- Frame construction is "c-channel" and 1.125 wide x 1.250 tall and will be a welded construction
- We tested a frame mock up over all the defenses. The comment is the Frise will require a belly pan
- The moat will require a chamfer on the bottom edge of the rear and front members
Transmission
- CIMple box from Andy Mark 12 x 56 tooth (4.167:1 reduction)
- Speed sensor will be mounted on the Cimplebox ecoder take-off
- The secondary reduction will be 12 x 36 tooth for a 14:1 overall reduction
- the design wheel speed is 10.29 ft/s loaded
- (We are considering mounting the drive chains on the outboard side of the wheel channel to create more space in the center of the robot)
- The chain from the 36T front wheel sprockets will be routed around a high idler to keep it away from obstacles between the wheels.
Bumpers
- Scaling team requested bottom edge of bumper height to be 5 1/4" off the floor
Gyro
- Analog Devices ADW22307 1-axis Analog Gyroscope
Battery Box
- Battery box design is forthcoming. Placement may be able to help tune the robot CG, depending on the placement of the other robot mechanisms/systems.
