func (*URArm) AddToLog

func (ua *URArm) AddToLog(msg string) error

AddToLog TODO.

func (*URArm) Close

func (ua *URArm) Close(ctx context.Context) error

Close TODO.

func (*URArm) CurrentInputs

func (ua *URArm) CurrentInputs(ctx context.Context) ([]referenceframe.Input, error)

CurrentInputs TODO.

func (*URArm) EndPosition

func (ua *URArm) EndPosition(ctx context.Context, extra map[string]interface{}) (*commonpb.Pose, error)

EndPosition computes and returns the current cartesian position.

func (ua *URArm) GoToInputs(ctx context.Context, goal []referenceframe.Input) error

GoToInputs TODO.

func (*URArm) IsMoving

func (ua *URArm) IsMoving(ctx context.Context) (bool, error)

IsMoving returns whether the arm is moving.

func (*URArm) JointPositions

func (ua *URArm) JointPositions(ctx context.Context, extra map[string]interface{}) (*pb.JointPositions, error)

JointPositions TODO.

func (*URArm) ModelFrame

func (ua *URArm) ModelFrame() referenceframe.Model

ModelFrame returns all the information necessary for including the arm in a FrameSystem.

func (*URArm) MoveToJointPositionRadians

func (ua *URArm) MoveToJointPositionRadians(ctx context.Context, radians []float64) error

MoveToJointPositionRadians TODO.

func (*URArm) MoveToJointPositions

func (ua *URArm) MoveToJointPositions(ctx context.Context, joints *pb.JointPositions, extra map[string]interface{}) error

func (ua *URArm) MoveToPosition(
	ctx context.Context,
	pos *commonpb.Pose,

	extra map[string]interface{},
) error

MoveToPosition moves the arm to the specified cartesian position. If the UR arm was configured with "arm_hosted_kinematics = 'true'" or extra["arm_hosted_kinematics"] = true is specified at runtime this command will use the kinematics hosted by the Universal Robots arm. If these are used with obstacles or interaction spaces embedded in the world state an error will be thrown, as the hosted planning does not support these constraints.

func (*URArm) State

func (ua *URArm) State() (RobotState, error)

State TODO.

func (*URArm) Stop

func (ua *URArm) Stop(ctx context.Context, extra map[string]interface{}) error

Stop stops the arm with some deceleration.
