NSK has developed a four legged, wheeled robot equipped with drive wheels on each of its legs which is capable of manoeuvring over flat and stepped terrain.
The robot is capable of autonomously recognising stairs through independent processing of external information detected through image and distance sensors, and then guiding the user up and down staircases. This resulted from the development of technology aimed at achieving an autonomous robot capable of assisting human eyesight, and has potential application as an alternative to wheelchairs, guide dogs and service dogs.
