# mdl_ball

Create model of a ball manipulator

MDL_BALL creates the workspace variable ball which describes the kinematic characteristics of a serial link manipulator that folds into a ball shape. By default has 50 joints.

mdl_ball(n) as above but creates a manipulator with n joints.

Also define the workspace vectors:

q joint angle vector for default ball configuration

## Notes

- Unlike most other mdl_xxx scripts this one is actually a function that behaves like a script and writes to the global workspace.
