In order to create the perfect robotic hand, scientists in Portsmouth and Shanghai are working on software that uses artificial intelligence to learn and copy human hand movements.
They hope to replicate this in a robotic device which will be able to perform the dexterous actions only capable today by the human hand. It also has the potential to revolutionise the manufacturing industry and medicine and, they anticipate, could lead to a better artificial limb.
Dr Honghai Liu, senior lecturer at the University of Portsmouth’s Institute of Industrial Research, and Professor Xiangyang Zhu from the Robotics Institute at Jiao Tong University in Shanghai, were awarded a Royal Society grant to further their research.
“A robotic hand which can perform tasks with the dexterity of a human hand is one of the holy grails of science,” said Dr Honghai Liu, who lectures in artificial intelligence at the University’s Institute of Industrial Research. The Institute specialises in artificial intelligence including intelligent robotics, image processing and intelligent data analysis.
High level of control
“We are talking about having super high level control of a robotic device. Nothing which exists today even comes close” he added:
Dr Liu used a cyberglove covered in tiny sensors to capture data about how the human hand moves. It was filmed in a motion capture suite by eight high-resolution charge coupled-device (CCD) cameras with infrared illumination and measurement accuracy up to a few millimetres.
Professor Xiangyang Zhu from The Robotics Institute at the Jiao Tong University in Shanghai said that the research partnership would strengthen the interface between artificial intelligence techniques and robotics and pave the way for a new chapter in robotics technology.
“Humans move efficiently and effectively in a continuous flowing motion, something we have perfected over generations of evolution and which we all learn to do as babies. Developments in science mean we will teach robots to move in the same way.”

Left leg in, left leg out: robot learns a few dance steps
Scientists in Japan have taught a human-sized robot to imitate the steps of a dancer. They say the prancing "dancebot" could be used to record the movements of traditional dances that are being lost as their performers die off.
