The rigid arm manipulator has the same full stroke "float" function as the pneumatic counterbalance crane and the soft cable auxiliary machine. The difference, however, is that in the event of torque, the pneumatic counterbalance crane or the flexible cable assisted manipulator cannot be used and the rigid arm assisted manipulator must be used. For example, if the centre of gravity of the workpiece is far from the arm's suspension point, or if the workpiece needs to be turned or tilted, then a rigid arm assisted manipulator is required, or if the factory height is limited, then a rigid arm assisted manipulator can be chosen.

　　Hard arm assisted grippers (including hard arm and soft cable) can add a booster pump to make the operation of the machine smoother if the air pressure at the user's site is insufficient. Working together various non-standard fixtures enable the light arm assisted robots to lift various forms of workpieces. Equipment methods can be floor fixed, suspension fixed or rail mobile.

　　Hard-arm assisted robots are mainly used to help human handling and to assemble workpieces and can be used in a variety of industries and sectors.

　　The advantages of a rigid arm assisted manipulator are significant, the manipulator is stable, the items are weightless and materials can be easily lifted to reach anywhere within the working area.

　　It is called a hard-arm powered robot because it consists of a hard-arm powered manipulator and a hard-arm lever. The hard arm assisted robot can only be used if there is torque resistance, for example, if the workpiece is far from the arm suspension point or if the workpiece needs to be reversed.

　　Depending on the customer's requirements, Intelligent Devices usually produces various types of assisted robot products. These are mainly customised to the needs of the user and include soft cable assisted robots, hard arm assisted robots, arm virtual robots, KBK tracks, assisted robots, etc. Although these have different names, there are certain isomorphic parts to the general composition structure. That is to say, the main functional parts that help the robotic arm.

　　I. Host part: It can achieve the gravity balance state of different weight items, and is suitable for the precise moving operation of the item. When handling empty, full loads and other workpieces, the system detects weight changes and achieves a floating state of the load in 3D space for precise placement. Features such as overall balance and smooth movement allow workers to handle, position and assemble workpieces with ease. The rigid arm allows the robot to carry the workpiece over obstacles. The system always keeps the robot's head level and exerts a high level of workability. The horizontal arm meets the requirements for movements such as lateral placement of material and lateral removal of material in the relevant place. For a wide range of material placement, a joint brake device brake with several rotating joints is equipped, so that the operator can stop the movement of the robot arm at any time during operation.

　　Secondly, the gas furnace control system section: the variable speed robot is equipped with a parts protection box to protect the main precision pneumatic components from accidental collisions and dust deposits during operation. The system is equipped with two components, a check valve and a gas tank to provide a constant and stable supply of compressed air to the system, providing safety for a certain period of time and enough power to complete the job or remove the workpiece.

　　III. Pneumatic fixture section: The mainframe control is integrated with the fixture (robot), allowing the operator to control the workpiece with both hands. The mainframe operating buttons are all integrated into the fixture control panel, and the control section and indicators and indicators are ergonomically placed to facilitate operation and emergency handling.
