Guess who's the latest to join the robot delivery bandwagon?

It's American headquartered courier delivery services company, Fedex which is testing an autonomous delivery device called 'SameDay' bot.

Retailers can take orders from nearby customers and the bot will deliver it to customers' homes or businesses on the same day.

The 'SameDay' bot uses artificial intelligence and an array of sensors to avoid obstacles and navigate.

An intelligent wheel system allows it to climb stairs and traverse various terrains. The 'SameDay' bot has a top speed of 10 miles/hr and can carry 100 pounds.

FedEx is partnering with companies like Autozone, Lowe's, Pizza hut, Target, Walgreens and Walmart.
