ServerVersion serverVersion() const noexcept
Returns the software version reported by the connected server.
bool grasp(double width, double speed, double force, double epsilon_inner=0.005, double epsilon_outer=0.005) const
Grasps an object.
bool stop() const
Stops a currently running gripper move or grasp.
GripperState readOnce() const
Waits for a gripper state update and returns it.
Maintains a network connection to the gripper, provides the current gripper state, and allows the execution of commands.
Definition: gripper.h:27
bool move(double width, double speed) const
Moves the gripper fingers to a specified width.
uint16_t ri_version_
Definition: gripper.h:153
std::unique_ptr< Network > network_
Definition: gripper.h:151
Contains the franka::GripperState type.
uint16_t ServerVersion
Version of the gripper server.
Definition: gripper.h:32
Describes the gripper state.
Definition: gripper_state.h:20
bool homing() const
