Disclosed is a robot including a variable length unit coupled to one section of at least one arm unit, wherein the variable length unit may include a motor, a first cam having at least one slit having a specific inclination in one area thereof, and a second cam, at least a portion of which is disposed in an interior of the first cam, and having at least one first boss that passes through the at least one slit of the first cam, wherein the first cam may be rotated through driving of the motor, the second cam may be linearly moved while the at least one first boss is guided by the at least one slit in correspondence to rotation of the first cam, and a length of the at least one arm unit may vary in correspondence to linear motion of the second cam.

This disclosure relates generally to a mobile robotic manipulator with telepresence system which includes a chassis assembly, a tilting arm assembly, and a rotary gripper assembly. The chassis assembly includes a chassis plate which mounts plurality of drive motors coupled with plurality of omni wheels through plurality of L mounting brackets; plurality of anti-toppling arms includes a plurality of linear guides which is mounted on a C mount plate; and plurality of linear actuators is mounted to expand or retract the plurality of anti-toppling arms. The tilting arm assembly includes a bottom fixed end of a front long actuator is mounted to a large rotating plate through plurality of C clamps. The rotary gripper assembly includes a top plate of a gripper is mounted and separated by gap with a bottom plate of the gripper to place a gripper actuator on top surface of the bottom plate of the gripper.

An extensible mast device allows a payload to be supported at a controllable distance from a supporting device. A motor driving a flexible strip provides a force through the flexible strip to extend the mast. The extended strip may have a curved cross section that provides some rigidity. A set of telescoping sections may enclose the strip. One or more of the sections may be flexible. In the event of an impact between the extensible mast and an object, such as a user, the flexible section and the strip yield to the impact and collapse. The extensible mast may be easily reset by lifting it back to a vertical position, with the flexible strip reasserting the curved cross section and the flexible sections resuming substantially the same shape as before the impact. A robot may use the extensible mast to elevate cameras or other sensors to a higher vantage point.

An apparatus includes a plurality of connector track elements, each extending substantially perpendicularly from a coupling plane, wherein a particular connector track element of the plurality of connector track elements includes a distribution of at least two magnets adjacent unattached end thereof, a polarity of the magnets on the particular connector track element being selected to provide magnetic repulsion as to at least one adjacent connector track element.

In a multi-part refueling device for refueling an electric drive battery or a fluid tank of a movable vehicle, simplified, reproducible refueling is to be achieved. The object is achieved in that the vehicle-side coupling device carried on the vehicle has connecting means designed as at least one charging coil, charging contacts or as a loading nozzle and also has a manipulator arm for descending, displacing and lowering the contact plate in a center of the stationary ground coupling device, wherein the manipulator arm comprises an upper arm segment pivotally and rotatably mounted on the vehicle side, a joint, a lower arm segment and a further joint for mounting the contact plate and is automatically controlled by the computer and control unit.

The present disclosure provides a smart grabbing device including: a controller, a container configured to accommodate articles, a grabber configured to grab the articles, and a movable mover. The mover is at a bottom of the container; the grabber is on the container; and both of the grabber and the mover are electrically coupled with the controller. The controller is configured to, control the mover to drive the smart grabbing device to move to a target position, and control the grabber to grab a target article and place the target article in the container.

In one example there is disclosed, an apparatus (10) for vacuum cleaning a tank (11). The apparatus (10) includes a main body (12) coupled to a working arm (14) and a plurality of support legs (16) coupled to the main body (12). The main body (12) includes a main conduit (40) extending lengthwise therethrough and a common central actuator (32) fitted about by the main conduit (40). The working arm (14) includes a vacuum conduit (50) in fluid communication with the main conduit (40). The plurality of support legs (16) are operatively coupled to the common central actuator (32) so as to be simultaneously moveable at least between a collapsed condition so as to fit through an opening 18 of the tank 11, and an extended condition in which the plurality of support legs (16) are moved relatively outwardly so as to be telescopically extendable within the tank (11) to engage a side wall (20) of the tank to support the main body (12). Other examples of the apparatus, a system and related methods are also disclosed.

The invention relates to a sorting system (100) for a machine tool for separating parts, in particular a laser cutting machine (200), having a gripper (110) that can be moved over a workpiece region (30) and is configured to receive cut parts (10) from the workpiece region (30), and an intermediate store (120) that can be moved over the workpiece region (30) and is configured to receive cut parts (10) from the gripper (110) and to unload the cut parts (10) into a store (40).

A magnetic pick-up tool, including a handle, a magnetic attraction head, and a telescopic rod. The magnetic attraction head is disposed in front of the handle. A first magnet is disposed on the magnetic attraction head. A front end of the telescopic rod is connected to a rear end of the magnetic attraction head. A rear end of the telescopic rod is connected to the handle. An illuminating lamp device capable of emitting light forwards is disposed on the magnetic attraction head. The illuminating lamp device capable of emitting light forwards is disposed on the magnetic attraction head and may be turned on as required for achieving free switching of auxiliary illumination, which have a wider illumination range on sides in a dark environment, so that users may pick up objects well and convenience is brought to the users.

The present disclosure provides a retractable pickup device. A chuck subassembly of the retractable pickup device includes: a control handle subassembly, a driving subassembly that is in driving connection with the control handle subassembly, and a chuck subassembly that is in driving connection with the driving subassembly. The control handle subassembly drives the chuck subassembly to be closed and opened through the driving subassembly, so as to achieve picking and placement of an object. The present disclosure has the beneficial effects that in the actual operation, the control handle subassembly is operated to drive the chuck subassembly to be closed and opened through the driving subassembly, so as to achieve picking and placement of the object. Therefore, the retractable pickup device after the improvement is simpler in both structure and operation, which further improves the operation experience of a user.
