There are two main types of limiting the movement of robots: mechanical and non-mechanical limits.

Restricted method of movement of the robot – Kawasaki robot

Restricted method of movement of the robot – Kawasaki robot

(1) Mechanical limit

Mechanical hard limits are used to physically restrain the robot beyond specified limits. Since this type of limit will have a physical touch with the robot, special attention needs to be paid to the use of such a limit method to ensure that the limit part does not physically deform after the collision.

(2) Non-mechanical limit: the safe soft limit of the shaft and space

This is a non-mechanical soft limit in which the built-in software determines the robot's motion limit. The axis limit can bind the trajectory of the robot; Spatial limits determine the geometry of proprietary areas.

Since this type of limit is set by the software, the permission to modify the parameters should also be strictly maintained by the password.

(3) Non-mechanical limiting: an external limiting device combined with a sensor

Another type of non-mechanical limit is the use of external sensors, such as safe proximity switches, non-touch coded switches, and even a virtual barrier formed by a safety light curtain, which actively activates the robot's safety abort signal when these external sensors receive a logical response that exceeds the limit.

The above two non-mechanical limit equipment, because they are controlled by a logic system in principle, need to consider the abort response distance of the robot.

	Industrial robots replace manual labor and improve economy - Kawasaki Robot The driving force is the replacement of human labor by machines. The reasons mainly come from two aspects: one is the lack of low-end labor supply. The post-80s and post-90s generations have become the main force of the labor market, compared with the post-60s and 70s, they have more demands, and one of the obvious changes is that fewer and fewer people are willing to engage in salary.
