A mobile robot is configured for operation in a commercial or industrial setting, such as an office building or retail store. The mobile robot can have a motorized base and a robot body on the motorized base, the robot body including a rotatable ring that rotates horizontally around the robot body. A mechanical arm that can contract and extend relative to the robot body is coupled to the rotatable ring and performs a plurality of actions. A controller of the mobile robot provides instructions to the rotatable ring and the mechanical arm and can cause the mechanical arm to open a door, take an elevator to move to a different floor, and test whether a door is locked properly.

A mechanism is constructed by twelve-axis geometry and controlled by spherical coordinate, so that all torques in twelve axes can be parallelly integrated. Timing belts, pulleys, hollow shafts, and spur gears onto four arc-link sets are included. Via these transmission components, base arc-links can be indirectly but synchronously rotated by base driving modules and terminal arc-links can be indirectly but synchronously rotated by terminal driving modules. The final output torque can be integrated via serial linking and parallel cooperating by the twelve rotating modules. Therefore, four arc-link sets work cooperatively and effectively in group but bear no burden each other. The mechanism can be applied to a multi-axis composite machining center machine or a multi-time element detection measuring bed and shoulder joints or hip joints corresponding to robots.

It also concerns a corresponding robotized positioning assembly and a corresponding method for positioning the tool in the predetermined position and orientation.

A controller of a robot turns over a workpiece into a second state by causing a first end effector to execute a holding operation of holding a first portion in a first state, causing the first robot arm to execute, after the holding operation, a lifting operation of lifting the first end effector such that a second sheet surface separates from a turnover station, causing the first robot arm to execute, after the lifting operation, a lowering operation of lowering the first end effector with a first sheet surface facing downward, and causing the first end effector to execute, before completion of the lowering operation and after the holding operation, a rotary operation of rotating about a first rotation axis in a direction of raising a first end portion.

The present process of controlling an industrial robot includes steps consisting of calculating, in the modules implemented by the central unit, a time-dependent composite setpoint defining articular forces and velocities, according to a target trajectory and to an operating mode; calculating, in modules implemented by the central unit, a behavior matrix which describes a desired behavior of the robot arm, defining directions along which the calculated composite setpoint is to be applied; calculating, in a module implemented by the in auxiliary unit, an articular force setpoint for controlling the axis controller module; and calculating, in the axis controller module implemented by the auxiliary unit, the control setpoints for the power units according to the articular force setpoint.

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.

The processor is configured to operate the multitude of joints in accordance with at least one of the manipulation mode and the various clutch modes.

A method for moving a manipulator arm. The manipulator arm includes a movable distal portion, a proximal portion coupled to a base, and joints between the distal portion and the base. The method involves calculating a first movement of the joints in accordance with a first objective. The method further involves calculating a second movement of the joints in accordance with a second objective. The first and the second movements are in a null-space of a Jacobian of the manipulator arm. The method also involves determining a combined movement of the joints by combining the first and second movements while limiting an overall magnitude of the combined movement without changing a direction of the combined movement, and/or combining the first and second movements while limiting a magnitude of the combined movement degree-of-freedom by degree-of-freedom. The method further involves driving the joints to effect the combined movement of the joints.
