The new robot was developed by Skype co-founders Ahti Heinla and Janus Friis. The self driving delivery machine drives on pavements at a pace of 4mph, and uses proprietary mapping and navigation technology to avoid crashing into obstacles.

The Starship is now going through testing periods, but plans to launch pilot services in the UK in 2016. Mr Heinla said the robots are primarily intended for use in suburban areas.

Each robot is designed to carry the equivalent of two grocery bags (20lbs). They will operate out of hubs – shipping containers that are specially built or co-located within grocery stores or warehouses. The robots will return to their hubs between deliveries to recharge and be cleaned if necessary.
