Abstract: An automatic fluid replacement device is adapted to be mounted on an opening of a storage barrel. The automatic fluid replacement device includes a robotic arm, at least one fluid convey joint and a controller. The robotic arm has a gripper. The fluid convey joint includes a convey pipe, a sleeve and a sealing bag. The convey pipe is configured to deliver a fluid. The sleeve is sleeved on the convey pipe. The gripper clamps the sleeve. The sealing bag is sleeved on the sleeve. The controller is configured for automatically controlling the robotic arm to move the fluid convey joint into the opening and controlling the sealing bag to be inflated to seal the opening.

Abstract: A power transmission mechanism and a robot arm using the same are described. The power transmission mechanism at least includes a first power source, a second power source, a plurality of steel ropes, a support arm component, a stopping component and a joint component. The stopping component is disposed in the support arm component and includes a first stopping unit and a second stopping unit that rotate coaxially. The first and second power sources and the joint component are disposed at two ends of the support arm component. The first and second power sources transmit power via the first stopping unit and the second stopping unit through the plurality of steel ropes to drive the joint component to perform a two-degree-of-freedom motion. The support arm component and the joint component can be applied in an upper arm and an elbow of a robot arm, thereby constituting a multi-degree-of-freedom robot arm.
