Problem

A central focus in the research area of human-robot cooperation (HRC) is the mobility of robot systems. The mobility of an HRC-capable robot system is defined as the rapid expansion of the robot workspace, as well as the rapid setup of such systems. The systems available on the market up to now each have specific disadvantages with regard to these aspects. This is especially true for linear axis systems, which are often also heavily oversized and associated with high acquisition costs.

Objectives

As part of the Robotix-Academy, ZeMA has built an HRC robot with a 7th axis that meets the criteria of rapid sequential expansion of the robot workspace and easy restart of the system by using additional sensor technology.

Approach

Roller conveyor, linear axis as well as the robot were implemented in the control unit. Subsequently, the safety for collaborating robots was validated using the Machinery Directive and the relevant standards. Part of this validation was the measurement of pressure and collision forces between human and robot.

Areas of application

This technology is used in the areas of special machine construction as well as in contract manufacturing.
