The American DIY chain Lowe’s is testing LoweBot, a customer service robot that speaks several languages, helps shoppers find items and provides information on products. First trialled as OSHbot two years ago, it is currently being tested in 11 Lowe’s stores. US electricals retailer Best Buy has Chloe, a robot that is a glorified grabber arm for CDs and DVDs, while Aldebaran Robotics, part of the Japanese telecoms firm Softbank, has created Pepper, a humanoid robot which has been deployed in some Nescafé stores in Japan. Some US shopping centres are even adopting robotic security guards – a cross between a CCTV camera and a Dalek that can detect people who may be loitering in the wrong place and read car number plates in car parks. But it’s not all been straightforward: a robot guarding a shopping centre in California recently ran over a toddler after its navigational scanning systems failed to detect the small boy.
