toppra is a library for computing the time-optimal path parametrization for robots subject to kinematic and dynamic constraints. In general, given the inputs:

1. a geometric path p(s), s in [0, s_end];
2. a list of constraints on joint velocity, joint accelerations, tool Cartesian velocity, et cetera.

toppra returns the time-optimal path parameterization: s_dot (s), from which the fastest trajectory q(t) that satisfies the given constraints can be found.

Documentation and tutorials are available here.

toppra was originally developed by Hung Pham (Eureka Robotics, former CRI Group) and Phạm Quang Cường (Eureka Robotics, CRI Group) with major contributions from talented contributors:

• Joseph Mirabel (C++ API)
• EdsterG (Python3 support).

If you have taken part in developing and supporting the library, feel free to add your name to the list.

The development is also generously supported by Eureka Robotics.
