Background technique

It is known that an instrument panel is often provided on a vehicle, and therefore a robotic hand is required to carry the instrument panel assembly. Conventional instrument panels are typically configured to be clamped on both sides by a robot, that is, conventional instrument panels are configured to be bilaterally stressed, such as by providing structural components such as stiffeners on the instrument panel. For this type of instrument panel, a robot held on both sides of the instrument panel can be used for handling.

However, with the improvement in the design of the dashboard, a half-armed dashboard has emerged. Among them, the new instrument panel design can not withstand bilateral forces, and only one side of the instrument panel can be stressed. For example, the left side of the instrument panel may include a metal beam that can be stressed, while the right side is formed of a non-stressed non-metallic structure.
