»View Product Info

Owning Palette: Dynamics VIs

Requires: Robotics Module

Calculates the joint torques that result from inertia given the joint accelerations you specify. Wire data to the joint positions input to determine the polymorphic instance to use or manually select the instance.

Use the pull-down menu to select an instance of this VI.

Manipulator Inertia Torque (Point)

Use this instance to calculate values at a single point.

serial arm in is a reference to a serial robotics arm. Use the Initialize Serial Arm VI to generate this LabVIEW class object.
joint positions specifies the joint angles that make up the robotic arm pose for which you want to calculate the solution.
joint accelerations specifies the acceleration of each joint in joint positions.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
serial arm out is a reference to a serial robotic arm. You can wire this output to other Robotic Arm VIs.
torques contains the amount of torque from inertia that each element of joint accelerations applies to the corresponding element of joint positions.
error out contains error information. This output provides standard error out functionality.

Manipulator Inertia Torque (Trajectory)

Use this instance to calculate values at points along a trajectory.

serial arm in is a reference to a serial robotics arm. Use the Initialize Serial Arm VI to generate this LabVIEW class object.
joint position trajectory specifies the joint angles of the robotic arm pose at points along a trajectory where each row represents a pose at a particular time and each column represents a particular joint.
joint acceleration trajectory specifies the acceleration of each joint in joint position trajectory.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
serial arm out is a reference to a serial robotic arm. You can wire this output to other Robotic Arm VIs.
torque trajectory contains the amount of torque from inertia that each element of joint acceleration trajectory applies to the corresponding element of joint position trajectory.
error out contains error information. This output provides standard error out functionality.
