Futurism.com reports that Volkswagen has unveiled a working prototype of a robot that can autonomously charge electric cars. “The Mobile Charging Robot is an adorable squat bot – which, when you get right down to it, is strikingly reminiscent of the R2-D2 droid from ‘Star Wars,’ bleeps and bloops included.” (Futurism.com, 28 December 2020) As a result, the service robot becomes a social robot. This may be a benefit for the video, but whether it is necessary in practice remains to be seen. The basic idea is that the robots move to cars that are parked in large residential complexes – and where there is not necessarily a human in the vicinity (and where therefore no social interaction is needed). But the concept is questionable in other respects as well. A mobile energy storage of this type seems to be inefficient: “basically, you’d have to charge the robot’s battery supply which it then uses to charge electric cars” (Futurism.com, 28 December 2020). Nevertheless, the idea should be pursued. Without a doubt, there are logistical advantages to having a robot drive to and charge cars – fewer charging stations are needed, and you can service two vehicles at once.
