Notable facts about Z1 AIR, its manufacturer and this type of robot
The first commercially sold cobot was a UR5 from Universal Robots, in December 2008.
Source: Universal Robots, company historyA cobot's payload includes the gripper. A 1 kg gripper on a 5 kg cobot leaves 4 kg for the product.
The safety rules for cobots are set out in ISO 10218 and ISO/TS 15066. The latter gives limit values for contact force per body part.
