Formal Language tools for robots.

• Doxygen API Documentation

Message passing IPC implemented over circular buffers in shared memory. Appropriate for real-time control because it does not suffer from head-of line blocking. Library has been verified with a SPIN model. More info on its wiki page.

Includes:

• A linear workspace (Cartesian) controller for robot arms that uses the Jacobian Damped Least Squares.
• Linear Quadratic Gaussian Filtering (Kalman Filter) and Control (LQR) for continuous and discrete time models.
• Trajectory generator for workspace trapezoidal velocity profiles, giving smooth straight-line motion of the arm.

Functions for numerical computation in lisp. Includes bindings for the more useful BLAS/LAPACK functions via CFFI. Unlike some other approaches, I use lisp-native arrays for our storage – on SBCL, allocating a lisp array is 10 times faster than allocating foreign storage. I've also avoided CLOS in an effort to reduce necessary overhead, doing some dynamic dispatching (if you want it) the old-fashioned (etypecase) way, which, with the right inlines and declarations, should be free.
