This robotic toilet might be more useful than a robot that does your chores. China’s Yueban built Xiaoban for people with limited mobility. Call it by voice or remote, and it comes to the bedside to help them use the toilet. It plans its own route, detects obstacles and navigates around them. Once in position, it locks its wheels and deploys supports so users can lean on the armrests as they sit down or stand up. It has a warm-water bidet and a warm-air dryer. Afterward, it heads to the bathroom, pumps waste into the existing toilet and rinses out its tank. No commode bucket for a caregiver to carry, empty or scrub. Yueban says the camera stays off while someone is using Xiaoban. It only turns on to locate the bathroom toilet during emptying. For older adults who struggle to get to the bathroom, especially in the middle of the night, this could be a huge relief.
