PlaCo: Rhoban Planning and Control

Planning & Control

PlaCo is Rhoban's planning and control library. It is built on the top of pinocchio, eiquadprog QP solver, and fully written in C++ with Python bindings, allowing fast prototyping with good runtime performances. It features task-space inverse kinematics and dynamics (see below) high-level API for whole-body control tasks.

Task-Space Inverse Kinematics

High-level API to specify tasks for constrained inverse kinematics (IK).

• See documentation
• Examples

Task-Space Inverse Dynamics

High-level API to specify tasks for constrained inverse dynamics (ID).

• See documentation
• Examples

Installing

PlaCo can be installed from pip

pip install placo

Or built from sources
