Manipulator Algorithm Design

Rigid body tree models, inverse kinematics, dynamics, trajectories

Robotics System Toolbox™ manipulator algorithms support workflows related to rigid body, articulated, and serial-link robots. You can import robot models from URDF files and Simscape™ Multibody™ models using importrobot, or load an existing model with loadrobot. Use these robot models for many different robot tasks:

Define your robot models using a rigidBodyTree object composed of rigid bodies with fixed, revolute, or prismatic joints. Generate joint configurations, define dynamics properties for inertial effects, and use joint- and task-space motion models to simulate robot motion.

Perform inverse kinematics to get joint configurations based on desired end-effector positions. Specify additional robot constraints other than the model parameters, including aiming constraints, Cartesian bounds, or pose targets.

Perform motion planning using your robot models and a rapidly exploring random tree (RRT) path planner.

Generate trajectories based on waypoints and other parameters with trapezoidal velocity profiles, B-splines, or polynomial trajectories.

Check for collisions with obstacles in your environment to ensure safe and effective motion for your robot.

Featured Examples

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 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.

Check for Environmental Collisions with Manipulators

Generate a collision-free trajectory in a constrained workspace. This example shows users how to inspect trajectories for collisions and manually design trajectories. An alternative is to use a motion planner as in Pick and Place Using RRT for Manipulators.
