Cozmo's lift remains perpendicular to the ground no matter how high it's raised.
What mechanism accomplishes this? Model it in SolidWorks and produce a
motion study.
Note: to demonstrate that the lift doesn't rotate:
- Click on plots/reports, select
Displacement/Velocity/Acceleration, then select Angular
Displacement and Magnitude. Click on the inner face of one of the holes in the
lift. Then click on the inner face of one of the holes in the body. You
should see a plot with a flat line.
- Create a second report of the same type, but this time click on the inner face of one of the holes
in a lift arm, and an inner face of a hole in the body. You should see a
diagonal line.
