Abstract: Disclosed is an injection gadget corresponding to an end-effector such as a rescue robot or the like. The injection gadget is configured such that an injection needle is disposed inside an injection assembly, an injection liquid is provided between a cylinder and a piston of the injection assembly, and the piston is moved by an elastic force of a spring previously compressed inside the cylinder so that the injection needle protrudes to the outside of the injection assembly and the injection liquid is ejected, and includes a bracket that replaceably mounts the injection assembly, a main body that is connected to the bracket and includes a first body space portion of which one side surface facing the bracket and the other side surface are open to pass through each other and a second body space portion that is disposed next to the first body space portion, a controller that is mounted in the second body space portion, a linear actuator that moves a transfer shaft in accordance with a control signal of the controller, and a pusher that is disposed between the linear actuator and the injection assembly, and transmits a force of the linear actuator toward the injection assembly so that a locking pin of the bracket is deviated from locking guides of the piston of the injection assembly.

Abstract: Provided are a wedge angle adjusting device and method. A device for adjusting a wedge angle of a variable wedge of an electro wedge brake (EWB) includes a movable wedge including an inclined surface and a counter wedge which includes an inclined surface disposed to face the inclined surface of the movable wedge and is disposed to face the movable wedge. The wedge angle adjusting device includes a frictional coefficient estimate unit configured to estimate a frictional coefficient between a pad and a disc of the EWB, a wedge angle command unit configured to calculate a wedge angle command value, based on a estimation of frictional coefficient estimated by the frictional coefficient estimate unit, and a wedge control unit configured to adjust the wedge angle according to the calculated wedge angle command value.

Abstract: An electro-mechanical brake for increasing a braking force is provided. The electro-mechanical brake for increasing the braking force according to an embodiment of the present invention may include the upper pad together with the inner pad and the outer pad, the inner pad may pressurize the inner side surface of the disk by the movement of the moving block by the rotation of the screw, the outer pad may pressurize the outer side surface of the disk, the upper pad may also pressurize the cylindrical surface of the upper end of the disk, and thus the braking force may be increased since the additional braking force can be further generated by pressurizing the cylindrical surface of the upper end of the disk compared with a case of pressurizing the inner side surface and the outer side surface of the disk.
