CAD SubassembliesSwing Arm - Assembly Views
• Swing arm is assembled primarily along the two swing axles. Swing arms are connected to a central gear motor, and through a dual chain and sprocket design rotate together 180 degrees out of phase.
• The encoder and encoder gears ensure that the microcontroller knows the location of the swing arms at all times.
• Exploded View to left shows logical assembly of swing arms.

CAD SubassembliesDrive Train - Bottom and Angle Views
• Drive Train Subassembly includes drive motors, sprokets, chains, tread pulleys, motor mounts, treads, traction wheels, axles, bushings, and several other components.
• The drive train assembly is the backbone of the entire chassis design.
• Drive train is designed to be perfectly symmetric in size and weight.

CAD SubassembliesRice Container Assembly
• Rice container design is based around carrying maximum rice volume within the ASME total vehicle dimension constraints (explains odd geometry).
• Rice door mechanism is assembled half to the rice container and half to the rice container door. When the solenoid raises the lock pins the door revolves downward and the force of gravity empties the bin.

CAD Full Vehicle AssemblyFull View and Size Constraint • The additional clear rectangular box
surrounding the vehicle represents the ASME dimension constraints• Team Burja is just within these requirements on all sides
• This is a full view with a good look at electronic components including microcontroller and H-bridges
