At the 18th China-ASEAN Expo, Chinese companies unveiled their self-developed delivery robots.

These robots are adorable and can walk as fast as human beings.

"Xiaojin" is a wet wipe vending robot, equipped with autonomous driving technology. It can sell wet wipes autonomously. The robot "Xiaoben" can take the elevator on its own. Each layer of it is enclosed separately, so the delivery process is safe and clean.

These robots have been in trail run at some catering companies, and are expected to be put into full use in the future.
