Apparatus and methods are described for performing a procedure using a robotic unit. A sterile drape is placed around a drape plate, such that the sterile drape is sealed with respect to the drape plate and forms an interface between a non-sterile zone and a sterile zone, a tool mount being disposed within the sterile zone, and one or more robotic arms and a linear tool motor being disposed within the non-sterile zone. A tool-actuation arm, disposed within the non-sterile zone, is driven to move linearly to thereby move at least the portion of the tool linearly with respect to the end effector. A portion of the sterile drape that is configured to be disposed at an interface between the tool-actuation arm and the portion of the tool that is pushed has greater rigidity and/or wearability than other portions of the drape. Other applications are also described.

A robot control device includes a generation unit that generates control information for controlling a robot to be controlled for each of a plurality of control cycles for the robot, an acquisition unit that acquires control environment information relevant to the control cycles, a selection unit that selects any one of a plurality of the control information based on the acquired control environment information and a relevance between the control environment information and the control cycles, and a control unit that controls the robot using the selected control information, thereby suitably controlling the robot according to the control environment of the robot in a case where the control cycles of the robot depends on the varying control environment of the robot.

When a predetermined stop condition is satisfied when a movable unit is in contact with an object in force control, a control apparatus stops the movable unit, and, when a predetermined restart condition is satisfied after stoppage of the movable unit, the control apparatus executes separation control to separate the movable unit from the object, and then, executes resetting of the force detection unit and restarts the force control after execution of the resetting. In another aspect, when a predetermined stop condition is satisfied when the movable unit is in contact with an object in the force control, the control apparatus performs separation control to separate the movable unit from the object, and then, stops the movable unit, and, when a predetermined restart condition is satisfied after stoppage of the movable unit, the control apparatus executes resetting of the force control, and then, restarts the force control.

A driving device includes a corrector, an actuator, and a position sensor. The actuator includes a nut connected to a movable part, a ball screw shaft onto which the nut is screwed, and a pulse motor that drives to rotate the ball screw shaft. The corrector includes a correction amount map in which a position correction amount for calibrating a predictable error is mapped for each position of the movable part. The corrector estimates an ideal movement position to which the movable part moves based on a command signal and refers to the correction amount map to calculate the position correction amount corresponding to a present position detected by the position sensor. The corrector generates a correction signal by correcting the command signal so as to reduce the difference between a corrected present position obtained by correcting the present position by the position correction amount and the ideal movement position.
