Problems solved by technology

However, the design and manufacture of linear motors is difficult, and its manufacturing process is complex and difficult to control. Therefore, it is not easy to use linear motors as parts of robots. Therefore, a linear motor that is easy to realize robot splicing is needed. This linear motor While being a part of the robot, it also has the attributes of a module
In addition, existing robots generally adopt transmission structures such as servo motors, reducers, and screw rods. There are many structural transmission parts. This method has disadvantages such as cumbersome assembly, difficult precision assembly, large backlash, inertia, friction, and insufficient rigidity.
And the key components of high-precision reducer and screw are imported; the robot's movement speed is limited by the structure, the movement speed and the load strength are limited, the robot is noisy during operation, and the energy consumption is high. Problems also plague the development of robots.

Description

technical field [0001] The invention relates to an automatic control robot, in particular to a robot combination splicing module. Background technique [0002] Existing robots are classified into parallel robots, series robots, and hybrid robots according to the connection mode. Series robots are also called multi-joint robots, which are connected in series through multiple joints and multiple drive shafts; parallel robots can be defined as moving platforms and The fixed platform is connected by at least two independent kinematic chains, the mechanism has two or more degrees of freedom, and is a closed-loop mechanism driven in parallel; the hybrid robot has both serial and parallel modes, and its degree of freedom Many, both series and parallel characteristics. The current robots mostly use rods or plates as the connecting parts of the robot, and use them with drive shafts or drive motors. This combination makes the design and connection of each robot relatively certain, an...
