Detailed Description

template<class State>
class HardwareInterfaceAdapter< hardware_interface::EffortJointInterface, State >

Adapter for an effort-controlled hardware interface. Maps position and velocity errors to effort commands through a position PID loop.

The following is an example configuration of a controller that uses this adapter. Notice the gains entry:

 head_controller:
   type: "effort_controllers/JointTrajectoryController"
   joints:
     - head_1_joint
     - head_2_joint
   gains:
     head_1_joint: {p: 200, d: 1, i: 5, i_clamp: 1}
     head_2_joint: {p: 200, d: 1, i: 5, i_clamp: 1}
   constraints:
     goal_time: 0.6
     stopped_velocity_tolerance: 0.02
     head_1_joint: {trajectory: 0.05, goal: 0.02}
     head_2_joint: {trajectory: 0.05, goal: 0.02}
   stop_trajectory_duration: 0.5
   state_publish_rate:  25
