Overview

This package contains a node that can be used to perform forward and inverse kinematics computations for the PR2 robot arms. The node exposes functionality that automatically cycles through the entire redundancy of the 7 DOF arms and provides collision free inverse kinematics solutions.

Services Offered

pr2_arm_kinematics_constraint_aware provides services for FK and IK computation and also services for computing collision free IK solutions. It can be configured using ROS parameters. The ROS API is explained in greater detail below. To get a generic (non-constraint aware) version of this node, check out the pr2_arm_kinematics package.

Services

node_namespace/get_ik (kinematics_msgs/GetPositionIK) node_namespace/get_fk (kinematics_msgs/GetPositionFK) node_namespace/get_ik_solver_info (kinematics_msgs/GetKinematicSolverInfo) node_namespace/get_fk_solver_info (kinematics_msgs/GetKinematicSolverInfo) node_namespace/get_constraint_aware_ik (kinematics_msgs/GetConstraintAwarePositionIK)
