Leg Subsystem Animation

To lighten the weight, this project choses 6061 Alloy pipes as the initial material to manufacture.
This material is cheap, light and fairly strong to support the weight of the whole product as well as an adult human.
Starting from choosing the proper size of the pipe on the market:
Considering the force and overall size of this project, 1/2″ S40 6061 Alloy Pipe is chosen.
Detail size: OD .840”, ID .522”, Thickness.109”, Length available on market: 1’, 3’, 6’
The manufacturing processes of the leg part will be 3 steps:
– Squeeze the pipe’s both ends
– Cut the flattened area with a round feature on each side
– Drill a clearance hole for the connecting shaft on each side
The sequence of manufacturing procedures is also applied in 3D-modeling in the software.
To reuse this file for all leg pipes, Design Table and Equations are used in SOLIDWORKS.
