The cofounders of Skype are launching a robot that will deliver groceries for £1

The cofounders of Skype, Ahti Heinla and Janus Friis, are building an autonomous, self-driving robot that will deliver up to 20lbs (9kg) of groceries for £1 ($1.50) in under half an hour, $4. 

The $4 and is "leading the revolution in local delivery," an industry that, $4, has UK sales of over £150 billion ($230 billion) per year.

Starship could be up to 15% cheaper than current delivery services, according to the founders, who did not specify how much it would cost them to make each Starship. 

Starship will travel on pavements at around 4mph (6.5kph) and will "only take the last few miles" after a more traditional delivery service - such as a van - does the rest. Due to its size, Starship can get into hard-to-reach places where a van could not. 

The robot can be tracked via a smartphone, making it easy to see where your bananas, apples or oranges are. If Starship runs into trouble it can be commanded by a human - like a drone - but the majority of its movement is self-directed based on mapping data and sensors. 

The first trials of Starship will take place in 2016 Greenwich, London.
