Meet the RODEM robot: a smart chair that moves you around without you having to break a sweat. It can work as a wheelchair or a simple electric chair for people with disabilities and mobility issues. The robot has a height adjustable seat. The 4 wheels are controlled separately to allow RODEM to turn on a dime.
The robot can be remotely controlled and summoned from a smartphone. It has a max speed of 6km/h and can handle slopes of 10 degrees. More info is available here.
