Brief: Nike's B.I.L.L. robot cleans and repairs sneakers; robot dog Loona launches crowdfunding, and more

Nike is testing B.I.L.L., a robot that cleans and repairs worn sneakers, at its flagship retail store in London; processing a pair of Air Force 1s takes about 45 minutes. Loona, the robot dog from Beijing-based KEYiTech, is on Kickstarter, with 1,402 backers and $469,100 raised so far. Tencent Robotics X Lab and a City University of Hong Kong team demonstrated a wearable haptic rendering device that operates at a voltage reduced to below 30 volts.
