Held from Nov 5 to 10 in Shanghai, the third China International Import Expo (CIIE) became “a perfect platform for promoting international innovation and cooperation”, People’s Daily noted. Let’s take a look at two of them.
Portable kayak
Lightweight equipment is what all sport lovers desire. At the CIIE, the French sporting goods company Decathlon launched its portable kayak ITIWIT X500. According to the company, the kayak measures 380 cm in length and 65 cm in width when inflated (充气). When not in use, it can be folded up to the size of a backpack. It consists of five independent air chambers. Even if two of them don’t work, the kayak floats are enough for sports enthusiasts to return to the shore safely.
Mind-reading ping-pong robot
Like ping-pong but afraid of criticism from your coach? The sixth generation of the Forpheus ping-pong robot from Japanese tech company Omron may help you. The robot has a robotic arm that can imitate humans. It can actually live up to the feeling of playing against a real opponent. At the same time, it can use sensors and five cameras to work out where you are and how you’re moving. After analyzing your abilities, it can adjust its own playing level to match yours. The robot “pursues harmony of humans and machines by patiently teaching us how to play ping-pong”, noted The Verge.
