• Robots learning to walk by the use of genetic algorithms

• Algorithms for machine learning
  
  Incremental evolution: In most practical applications the search space for a genetic algorithm is very large. For realtime hardware evolution time is therefore a mayor limitation in the search for advanced solutions. We are exploring incremental techniques to reduce the size of the search space in an optimal way. We are using different hardware walking machines to verify our results.

• "Mono"

• Mono is a one-legged pneumatic foot. 2 pneumatic cylinders. Electrically (binary) controlled by PC. Learns to jump fast forward by evolution in less than 3min. Feedback: angle sensor.
  Mono has demonstrated realtime evolution in a stage show seen by 4600 students at the NFR "ungforsk" science fair, Blindern, Oslo, Oct. 2004. Mono has also performed outdoor at NFR "forskningstorget" science fair 2004.

• The bionic arm project

• Bionic arm: How close to biology can we make an arm prosthesis? Will a future arm prosthesis be a complete replacement of the original biologic arm? We believe that a future arm prosthesis will be directly controlled by the nerves is the remaining limb. We also believe that the user will "feel" the arm in a way that resembles the feeling from the original biological arm. This can be made possible by the use of sieve microelectrodes which are operated in to the nerve of the remaining limb. The sieve electrode can both receive signals from the nervous system, and at the same time send artificial generated sensory signals back to the nervous system.
  
  
  Activity A: We are investigating the possibility of using artificial muscle fibers to actuate the 5 fingers and the wrist of the prosthesis.
  The output control signal from the sieve electrode will consist of hundreds of channels with information from the nervous system. These signals must be sorted and adapted to control the artificial muscle fibers.
  
  Activity B: We are currently testing artificial neural networks used for signal sorting and muscle control (simulated control signals).
