Various arrangements for remote control battery compartment cover removal systems and methods are presented. A sensor may measure the distance from the sensor to a remote control that is inserted into a housing. An extendable arm may have a compressible impact component, such that when the extendable arm is extended from an unextended position and the remote control is inserted into the housing, the compressible impact component actuates a latching mechanism of the remote control's battery compartment cover.

A robotic joint that includes a hydraulic actuator. The hydraulic actuator includes a hollow tube that has a first opening at a first end of the hollow tube and that has a second opening at a second end of the hollow tube. The hollow tube contains hydraulic fluid. A moveable magnet moves within hollow tube as a result of a magnetic field within the hollow tube. A magnetic field source located outside the hollow tube creates the magnetic field within the hollow tube. When the moveable magnet moves to the first end of the hollow tube, a first piston pushes hydraulic fluid out of the first opening. When the moveable magnet moves to the second end of the hollow tube a second piston pushes hydraulic fluid out of the second opening.

An end manipulator for picking packages is provided. An example end manipulator includes a vacuum plate coupled to a machine where the vacuum plate includes a first set of vacuum cups. Further, the end manipulator includes a grasper plate movably coupled to the machine. The grasper plate moves between a retracted position and an extended position. In the retracted position, the grasper plate aligns with the vacuum plate such that the grasper plate abuts the vacuum plate. In the extended position, the grasper plate extends out from the vacuum plate. In some examples, when the grasper plate is in the retracted position, the end manipulator is configured to pick and place a first type of package. Further, in some examples, when the grasper plate is in extended position, the end manipulator is configured to pick and place a second type of package.

Manual, automated, or semi-automated articulating arm programmable tank cleaning nozzle systems, devices and methods for providing safe and efficient methods for removing paint, rust, scale, debris, and contaminants as well as methods to apply new coatings to tanks. A hydraulically controlled articulating arm can have up to 11 or more degrees of freedom and a working envelope ranging from approximately 10approximately 10approximately 10 up to approximately 50approximately 50approximately 50. Modularity and light weight components allow quick setup with minimal manpower, and therefore, make relocation in confined tanks feasible. Simplified programming with scanning methods can aide in quick generation of toolpaths. Dust free blasting techniques can be employed, making the operation safer, cleaner, and more efficient. Surface coatings can be applied with the same device further increasing efficiencies. The systems, devices and methods can work in the presence of flammable vapors and dust.

A compliance mechanism for holding a robotic finishing tool implements passive force control and compliance using one or more double-acting pneumatic pistons. A desired application force is set and maintained by controlling pneumatic pressure in chambers both fore and aft of the one or more double-acting pneumatic pistons. The pressures in the fore and aft chambers are dynamically controlled, e.g., in response to changes in spatial orientation of the robot arm and tool, to maintain a desired compliance force applied by the robotic finishing tool to a workpiece. An external regulator maintains the fore and aft chamber pressures, for a given spatial orientation, throughout the holder's range of compliance motion. The compliance mechanism includes a plurality of piston bores; the number of active pistons may be adjusted for a given operation, e.g., in response to the finishing tool weight.

A head for a swing arm assembly is provided for a spot welding machine. The head can accommodate a tip dresser or a tip exchanger.

The present disclosure provides a base robot. The robot includes a base; a multi-piece housing movably mounted on the base covering a part of the base when the housing is closed, and exposing the base when the housing is opened; and a driving assembly connecting the base and the housing, and driving the housing to move relative to the base, and opening or closing the housing.

A bionic robot and a spine apparatus thereof. Magnetorheological fluids are filled in the cavity, the first tube and the second tube to actuate the first end of the piston rod, so that the piston rod is actuated to move along the axial direction of the cavity. The excitation coil is wound around the first tube. When the controller provides a variable current for the excitation coil, the excitation coil produces a variable magnetic field at the first tube, thereby causing a magnetorheological effect that the magnetorheological fluid is in low liquidity and high viscosity. Then, the transmission speed of the piston rod is changed, which is presented as a damping characteristic, reducing the pause and transition in the spine apparatus, and improving the flexibility and the bionic performance of the robot.

Various example embodiments described herein relates, to an item manipulation system that can include a control system and an end effector. The end effector can include a tube defining a channel between a first end and a second end. The tube can include, a flexible suction cup that can be disposed within the channel of the tube. In some examples, the flexible suction cup can engage a surface of the item based on suction force generated through the flexible suction cup. The end effector also includes a linear actuator that can be mechanically coupled to the flexible suction cup. The end effector can be configured to: extend, the flexible suction cup towards the second end of the channel to position at least a portion of the flexible suction cup outside the tube and retract, the flexible suction cup within the channel to position the flexible suction cup within the tube.

The present disclosure provides a wheel hub carrying manipulator which comprises a stand column, a forearm driving device and a claw hand device, wherein the stand column is fixed in the vertical direction, the claw hand device can drive a claw hand assembly to clamp and release a wheel hub through a connecting rod, by the manipulator, assembly line operation can be realized, the production efficiency can be greatly improved, the structure is simple, and the maintenance cost is low.
