A tiny prototype robot that functions like a living creature is being developed which one day could be safely used to pinpoint diseases within the human body.
Called ‘Cyberplasm’, it will combine advanced microelectronics with latest research in biomimicry (technology inspired by nature). The aim is for Cyberplasm to have an electronic nervous system, ‘eye’ and ‘nose’ sensors derived from mammalian cells, as well as artificial muscles that use glucose as an energy source to propel it.
The intention is to engineer and integrate robot components that respond to light and chemicals in the same way as biological systems. This is a completely innovative way of pushing robotics forward.
Cyberplasm is being developed over the next few years as part of an international collaboration funded by the Engineering and Physical Sciences Research Council (EPSRC) in the UK and the National Science Foundation (NSF) in the USA. The UK-based work is taking place at Newcastle University. The project originated from a ‘sandpit’ (idea gathering session) on synthetic biology jointly funded by the two organisations.
Cyberplasm will be designed to mimic key functions of the sea lamprey, a creature found mainly in the Atlantic Ocean. It is believed this approach will enable the micro-robot to be extremely sensitive and responsive to the environment it is put into. Future uses could include the ability to swim unobtrusively through the human body to detect a whole range of diseases.
The sea lamprey has a very primitive nervous system, which is easier to mimic than more sophisticated nervous systems. This, together with the fact that it swims, made the sea lamprey the best candidate for the project team to base Cyberplasm on.
Once it is developed the Cyberplasm prototype will be less than 1cm long. Future versions could potentially be less than 1mm long or even built on a nanoscale.
“Nothing matches a living creature’s natural ability to see and smell its environment and therefore to collect data on what’s going on around it,” says bioengineer Dr Daniel Frankel of Newcastle University, who is leading the UK-based work.
Cyberplasm’s sensors are being developed to respond to external stimuli by converting them into electronic impulses that are sent to an electronic ‘brain’ equipped with sophisticated microchips. This brain will then send electronic messages to artificial muscles telling them how to contract and relax, enabling the robot to navigate its way safely using an undulating motion.
Similarly, data on the chemical make-up of the robot’s surroundings can be collected and stored via these systems for later recovery by the robot’s operators.
Cyberplasm could also represent the first step on the road to important advances in, for example, advanced prosthetics where living muscle tissue might be engineered to contract and relax in response to stimulation from light waves or electronic signals.
“We’re currently developing and testing Cyberplasm’s individual components,” says Daniel Frankel. “We hope to get to the assembly stage within a couple of years. We believe Cyberplasm could start being used in real-world situations within five years”.

EPSRC is the main UK government agency for funding research and training in engineering and the physical sciences, investing more than £800 million a year in a broad range of subjects – from mathematics to materials science, and from information technology to structural engineering.
National Science Foundation (NSF)
NSF is an independent federal agency created by the US Congress in 1950. With an annual budget of about $6.9 billion (FY 2010), it is the funding source for approximately 20 per cent of all federally-supported basic research conducted by America's colleges and universities. In many fields, such as mathematics, computer science and the social sciences, NSF is the major source of federal backing.
