Supermarket chain Tesco have completed a trial of a ‘delivery robot’, capable of carrying 2 grocery bags and delivering within five and 30 minutes from the retail outlet. The robots are driven autonomously for 99% of their journey, providing an environmentally-friendly choice for the last mile deliveries.  The robot technology was developed by Starship Technologies, with chief executive Ahti Heinla noting that many retailers had declared interest in working with the company.
