| ros::Duration pr2_hardware_interface::ActuatorState::sample_timestamp_ |
The time at which actuator state was measured, relative to the time the ethercat process was started. Timestamp value is not synchronised with wall time and may be different for different actuators. For Willow Garage motor controllers, timestamp is made when actuator data is sampled. sample_timestamp_ will provide better accuracy than ros::Time::now() or robot->getTime() when using a time difference in calculations based on actuator variables.
Definition at line 78 of file hardware_interface.h.
The time at which this actuator state was measured (in seconds). This value should be same as sample_timestamp_.toSec() for Willow Garage devices. The timestamp_ variable is being kept around for backwards compatibility, new controllers should use sample_timestamp_ instead.
Definition at line 85 of file hardware_interface.h.
The velocity in radians per second.
Definition at line 92 of file hardware_interface.h.
A bias applied to the position value when reported. This value is written once after calibration. The reported position is the hardware's actual position minus the zero offset.
