Package delivery could be about to change, at least for residents of Milton Keynes, as a UK start-up launches the world's first robot package delivery service.

Starship Technologies will unleash hundreds of robots to deliver packages to people's front doors at any time they want using autonomous six-wheel robots.

The start-up has already tested its robots for food delivery on the streets of London and has released them on the campuses of several companies in California to deliver lunches.

Users who sign up to Starship's mobile phone app will receive a "personal address" in place of their home address for their packages. These will be delivered to a Starship sorting hub and then assigned to a delivery robot.

The robot can then be ordered to trundle to their front door at a convenient time, while users can track its progress from the company's app. Deliveries will cost users a subscription fee of £7.99 per month. The company has already been running a fleet of around 20 delivery robots in Milton Keynes for food delivery working with the Cooperative.
