These Robotics System
Toolbox™ algorithms support workflows related to articulated robots. Define
your robot model using the
RigidBodyTree class, which is made
up of rigid bodies as structural elements and joints for attachment and motion. This
robot representation contains kinematic constraints and dynamics properties. You can
perform inverse kinematics and dynamics calculations on this robot model. If you
have a robot description as a URDF file, you can import it using
