US-based robotics company Boston Dynamics teased the commercial launch of its four-legged robot SpotMini on Tuesday (April 16), with a video showing a group of them pulling a truck.
The video published to YouTube showed 10 of the robots tethered together, pulling the truck across the Boston Dynamics car park in Waltham, Massachusetts.
The company has gained popularity on YouTube over the past few years with videos showing its robots walking up hills, up stairs and opening doors.
In May 2018 the company's founder and CEO Marc Raibert told a technology event at the University of California, Berkeley, SpotMini was in pre-production in readiness for a commercial release.
The company has its origins in the Massachusetts Institute of Technology where it developed its first robots which moved like animals, its website says.
It was purchased by Google for an undisclosed amount in December 2013 and sold to Japanese multinational SoftBank Group Corp in June 2017.
The SpotMini weighs 25-30kg (55-66 pounds), is electric-powered and can operate for 90 minutes.
It is fitted with multi-purpose arm used for picking up and handling objects.
It also has multiple sensors that survey the world around it and keep it stable, the company says.
