3) Kinematic Analysis & Synthesis

Position analysis and mobility calculations were mostly conducted experimentally. Given the scenario of a single motor driven mechanism with clear, linear outputs, we were able to conclude that the system maintained a singular degree of freedom. Position analysis was performed with the design of the scissor lift. The original expectation for the theoretical bounding box was defined through the maximum height allowed from the lift (10 in). Next, the minimum height was determined through the design of the retractable shaft since the bottom position of the shaft was the physical limit of the lift platform. Velocity analysis was performed on the lift as we set requirements for the lifting motion to take no more than 10 seconds. 10 seconds was determined to reduce the observer’s idling time and maximize satisfaction.
