Improving Tricycle Biomechanics: Concept Tricycle Biomechanics Team March 22, 2007 Xin He, Katherine Wong, Mario Bollini, Elizabeth Au, Lindsay Todman
Community Partnership Abdullah: tricycles versus wheelchairs Medical, environmental, stigmatic reasons Rory: synchronous versus asynchronous crank Power efficiency, mobility General difficulty in communication
Concept: Modify Current System Provides tangible results for community partners by the end of the term. Will seek to optimize: Gear ratio Crank configuration (synchronous vs. asynchronous) Crank position Steering system
Modules Steering Gears Ratio, derailers, speed, arms Crank Symmetric and Asymmetric Adjustability Position
Next Step: Testing power output Find the maximum power output for different people using the hand crank This power output should be measured for a reasonable period of time to ensure it is sustainable Vary the position of the crank and see how the power output changes
