Canfield Joint Simulation

Forward kinematics: Vary the base angles (thetas) to control the Canfield joint. You can hit the PLAY button next to a constant to change its value.

Inverse kinematics: Drag the center of the top plate around and note the changes in the base angles. Some points have more than one solution; some points have none. Can you find the edges of the workspace?
