A robot system for carrying out work in two different work areas comprises a support unit positioned between the two work areas, an elongated beam arranged on the support unit such that the elongated beam is allowed to linearly move between a first position, where a first end portion thereof extends out over a first work area, and a second position where a second end portion thereof extends out over a second work area. The robot system further comprises a robot, a suspension unit configured to hold the robot and arranged on the elongated beam such that the suspension unit is allowed to move along the elongated beam, and a drive arrangement configured to individually move the elongated beam and the suspension unit, thereby allowing the robot to selectively operate in each of the two work areas.

A cleaning apparatus includes a nozzle assembly and an arm supporting the nozzle assembly. In some embodiments, the arm includes a first rotatable arm member defining a first axis and a second rotatable arm member defining a second axis and connected to the first rotatable member. In certain examples, the first rotatable arm is rotatable about the first axis and the second rotatable arm is rotatable about the second axis. The cleaning apparatus also includes at least one sensor on the arm and configured to detect a position of the nozzle assembly based on rotation of the first rotatable arm or the second rotatable arm

The aim of the invention is to provide a concrete printer which allows complex concrete elements and structures to be erected within a short time with the inclusion of a reinforcement and surfacing process. The concrete printer according to the invention, in particular for producing concrete elements and structures, has a vertically (Z) movable jack lift (6) which can be moved on two perpendicular rails (3) by a first drive unit (5). The jack lift (6) is connected to a longitudinal crossbeam (7) oriented horizontally in the longitudinal direction (X), and the longitudinal crossbeam (7) is connected to two guide rails (8) oriented in the longitudinal direction (X). A transverse crossbeam (9) which is oriented perpendicularly to the longitudinal crossbeam (7) can be moved along the guide rails (8) by a second drive unit (10), and at least one working head (13) is provided which can be moved along the transverse crossbeam (9), comprises at least one concrete printing nozzle (11), and can be moved by a third drive unit (12). The actuation of all the drive units (4, 5, 10, 12) and the concrete printing nozzles (11, 11a, 11b) is carried out by a control unit (41). In the method according to the invention, supporting concrete (18) is first cast or dispensed from a supporting concrete nozzle (11a) for an outer contour (18) and/or an inner contour (18). Reinforcement rods (31) are then optionally inserted, and the intermediate spaces (47) between the supporting concrete portions (18) and optional reinforcement rods (31) are then cast with liquid concrete (19) from the liquid concrete nozzle (11b).

An electromechanical system operates through physical interaction with an operator, and includes a plurality of joints providing multiple degrees of freedom (DOF), including actuated joints and unactuated joints. The unactuated joints are distal with respect to the actuated joints and are in redundant DOF to the actuated joints. The system includes a plurality of actuators each configured to actuate one or more of the actuated joints, and a plurality of sensors each positioned with respect to a respective one of the actuated and unactuated joints. Each sensor is configured to measure corresponding joint data indicative of a position or angle of the respective actuated or unactuated joints. A controller in communication with the sensors receives the measured joint data as feedback signals, generates control signals using the feedback signals, and transmits the control signals to the actuators to thereby control an actuation state of the actuators.
