Manipulator Algorithm Design

Rigid body tree models, inverse kinematics, dynamics, trajectories

These Robotics System Toolbox™ manipulator algorithms support workflows related to articulated, serial-link robots. Define your robot model using a rigidBodyTree object made up of rigid bodies as structural elements and joints for attachment and motion. This robot representation contains kinematic constraints and dynamics properties. Use joint- and task-space motion models to get robot motion given input commands.

If you have a robot description as a URDF file or Simscape™ Multibody™ model, you can import it using importrobot.

Perform inverse kinematics to get joint configurations based on desired end-effector positions. Apply additional external constraints like aiming a camera at your workspace. Generate smooth trajectories for planning and executing planned paths. Detect collisions or calculate clearance to avoid collisions while executing paths.

Plan and Execute Task- and Joint-space Trajectories using KINOVA Gen3 Manipulator

Plan and Execute Task- and Joint-space Trajectories using KINOVA Gen3 Manipulator

Generate and simulate interpolated joint trajectories to move from an initial to a desired end-effector pose. The timing of the trajectories is based on an approximate desired end of arm tool (EOAT) speed.

Plan and Execute Collision-Free Trajectories using KINOVA Gen3 Manipulator

Plan and Execute Collision-Free Trajectories using KINOVA Gen3 Manipulator

Plan closed-loop collision-free robot trajectories from an initial to a desired end-effector pose using nonlinear model predictive control. The resulting trajectories are executed using a joint-space motion model with computed torque control. Obstacles can be static or dynamic, and can be either set as primitives (spheres, cylinders, boxes) or as custom meshes.
