Take my lead: A scientist wearing a blindfold starts opposite some stairs at the developer's lab in JapanIt might be some time before one of these is bounding through the local park but a new 'robo-dog' could make life easier for blind people.
The robot was created by Japanese developer NSK, along with the University of Electro-Communications, and uses a Microsoft Kinect image and distance sensor to create a 3-D visualisation of obstacles ahead.
A video showed the robotic dog leading a blindfolded scientist up and down a flight of stairs at a little slower than walking pace.
Sit boy: The 'dog' bends its legs with the help of robotic hinges as it starts to negotiate the flight of stairs Last week, car manufacturer Toyota unveiled plans for a high-tech robot nurse that is able to lift disabled patients out of bed and can help them walk.
The Independent Walk Assist robot - a computerised metallic leg brace was designed to help with rehabilitation - and the Patient Transfer Assist, which can transport the bed-ridden to the toilet, were unveiled during a press conference in Tokyo.
The second gadget - the patient transfer machine - showed how the bed-ridden could be taken from the ward to the bathroom, easing the physical burden on nurses moving patients.
Toyota hopes to introduce the devices sometime in 2013 and believe it has great potential in Japan, one of the world's most rapidly-ageing nations.
