Presentation Transcript

  1. Structural Design Considerations • Small or 0° turn radius • Given size restriction and ground clearance • Friction • Type of drive-train • Weight and center of gravity location

  2. Wheels • First considered to determine range of chassis size to work with • Quantity and type which help with finalizing drive-train • Explored track style, multi-directional and standard hobbyist rubber wheels • Size to provide enough ground clearance

  3. Chassis and Drive-train • Shapes and sizes • Square, triangular and rectangular • Material • Lightweight and easy to machine • Deck quantity • Quantity, speed and torque of motors • Steering mechanism

  4. Wheels-Current Design • Multi-directional • Rubber coated to provide enough friction • (4) 4” diameter wheels • Assembled 90° apart • Provides 0° turn radius

  5. Chassis and Drive-train/Current Design • Octagonal shape keeping wheels 90° apart • Aluminum chassis • Two decks • Four modified servos to drive • No steering required

  6. Rough Assembly Sketch
