The general trend of composite mobile robots

Internationally, the composite mobile robot is called Moma (Mobile Manipulator), which is mainly composed of an AMR chassis, a collaborative robotic arm, vision, and corresponding end effectors. The AMR chassis gives the composite mobile robot the ability to move flexibly, and vision gives eye perception. The robot arm and the corresponding end effector give the compound mobile robot the ability to operate.

In Xu Zhen's view, the most essential point of the composite mobile robot is that it is closest to the human state. The lidar and vision modules built into the chassis and robotic arm constitute its "eyes", and the robotic arm allows it to have The general operating ability of the "hand", the chassis makes it move like a "leg", which directly leads to the result that traditional mobile robots generally have only 3 degrees of freedom, while composite mobile robots with different end tools can have 9 The above degrees of freedom.

In fact, the composite mobile robot greatly enhances the reach of the robot's work range by means of mechanical arm + vision, compared with a single mobile chassis and mechanical arm, and can be applied to more occasions.

At present, the main application scenarios of composite mobile robots are divided into two categories, the industrial manufacturing field and the intelligent inspection operation and maintenance field.

In the production process of precision electronic manufacturing represented by semiconductors, materials are circulating. The composite mobile robot mainly uses small, light-loaded collaborative robotic arms, which have high efficiency, continuity, accuracy, flexibility and Safety, it can work with people in the workshop to become an intelligent solution that integrates the functions of material caching, handling, loading and unloading. In this scenario, the composite mobile robot can replace most of the boring tasks such as transportation and loading and unloading.
