Equipment and Facilities category, third prize:One hundred tiny painters by Dr Edmund Hunt, University of Bristol In the future, large groups of nanoscale robots could work on tasks such as delivering drugs to tumours. Ants lay pheromones on the ground to communicate indirectly. One behaviour is laying territory-marking pheromone so that other ants know the area has already been explored. Tiny, light-sensitive robots could be manipulated under the microscope in such a way in future nanomedicine. Work at Bristol Robotics Laboratory with Sabine Hauert and Jerry Wright
