| gripper_action_controller::GripperActionController< HardwareInterface >::Commands | Store position and max effort in struct to allow easier realtime buffer usage |
| gripper_action_controller::GripperActionController< HardwareInterface > | Controller for executing a gripper command action for simple single-dof grippers |
| HardwareInterfaceAdapter< hardware_interface::EffortJointInterface > | Adapter for an effort-controlled hardware interface. Maps position and velocity errors to effort commands through a position PID loop |
| HardwareInterfaceAdapter< hardware_interface::PositionJointInterface > | Adapter for a position-controlled hardware interface. Forwards desired positions as commands |
