Sketch Review Page: Concept generation
Austin:
- uses second stage belt reductions mainly everywhere
- for the base uses cycloid
- has a bit past 180 degree rotation a the base
- get the arm to go back to 300 degrees
- mentioned 300pound limit for the linear actuator
- use belt to rotate the arm as well
- can move up and down about 4.5 feet
Mathieu:
Concept 1
- uses cycloid base
- uses linear actuator rotate link connected to axis 2
- double end effector design, with allen key and claw shifted 90 degreesseveral designs
Concept 2
- cycloids on pretty much all joints, with allen key fixed inside claw
Concept 3 - SKELETOR
- uses extra links attached on all joints to keep part of axis 4 parallel to ground at all times
- Differential drive is used to rotate the claw up and down
- In theory would have a greater lifting strength than it's alternatives
Ethan:
- 3 coaxial shafts (sheathed) are used to power axis 4,5 and 6
- concentric hypoid gears are powered by separate shafts to move axis 5 and 6 (complex gearing)
