How our mechanism works
á Structure built to bring servo close to the 1 lb weight.
á Mechanism uses lever arm to transform rotational work done by servo into upwards translational work to lift the weight.
á Use of a counterweight to achieve higher lift
Smaller fraction was used due to uncertainties in actual torque produced by servo, as well as imperfections such as resistive frictional torque.
Our actual height was 3 in, due to the counterweight hitting the ground before maximum lift was achieved.
Interesting and original features (Things we are most proud of)
á Very sturdy and stable structure
á Use of L- and U-beams, 60 degree angle trusses
á Double bolt design on base gives extra stability
á Supports calculated and placed to give optimal results
á Well planned and designed: each part was carefully calculated, measured, and cut out
á CAD modeling using Solidworks to give conceptual idea of design
