Robots are already being used in business environments to get things done. The Panasonic Assist Robot is a wearable solution that uses advanced control and sensor technologies to help people lift heavy objects. Such a technology could also be used to make life easier for the elderly.
The AWN-03 provides lower back support and automatically senses when the wearer is lifting and holding heavy objects to activate its motors. It can reduce stress on the user’s lower back by 15 kg. The above video provides more information on this idea.
