The robot - which has been designed by British company Engineered Arts - revealed that engineers are working on 'prototype legs' which should be ready within the next year. During a Q&A on YouTube, Ameca said: 'I can't walk, but I have seen prototype legs in the Engineered Arts lab. The design of my legs is inspired by the robot Byrun, developed by Engineered Arts Ltd. It has unique mechanical properties that allow it to walk without using too much energy.'
