With the progress of science and technology, many other forms of robotic products have been developed outside the robotic arm, which have made great progress in sensor, computing ability, planning and control, human-computer interaction, artificial intelligence and so on.

The research and application of humanoid robots has become one of the most active research hotspots in the field of intelligent robots. Robot arm is the most representative and complex component in humanoid robotic systems.

At present, the market of industrial manipulator is very mature. It is mainly used in the production lines of workshop welding, assembly, spraying, polishing and handling, with high precision, heavy load and high speed.

Robot hands often have built-in pressure sensors, which are used to tell the computer the strength of the robot when it grasps a particular object. This keeps the object in the robot’s hand from falling or being crushed. Other end effectors include spray lamps, drills and lacquer sprayers. Industrial robots are designed to perform exactly the same tasks repeatedly in controlled environments.

Robot arm, mainly refers to the joint robot with series structure, the degree of freedom is much lower than that of the five-axis robot, and the range of motion of the output axis of the end is mainly confined to a plane. It is suitable for large batch workpieces with simple structure.

Robots try to assess the hardness of an object by placing it on a flat surface and then poking it lightly. But that’s not the main way humans measure hardness. We judge it by pressing the contact area between the object and the finger. Generally speaking, softer objects tend to flatten and increase the contact area with fingers.
