Chemical Processing by Swarm Robotics
Start date: Jun 1, 2008,
End date: May 31, 2013
The aim of the project is to develop chemical processing systems based on the principle of swarm robotics. The inspiration for swarm robotics comes from the behaviour of collective organisms – such as bees or ants – that can perform complex tasks by the combined actions of a large number of relatively simple, identical agents. The main scientific challenge of the project will be the design and synthesis of chemical swarm robots (“chobots”), which we envisage as internally structured particulate entities in the 10-100 µm size range that can move in their environment, selectively exchange molecules with their surrounding in response to a local change in temperature or concentration, chemically process those molecules and either accumulate or release the product. Such chemically active autonomous entities can be viewed as very simple pre-biotic life forms, although without the ability to self-replicate or evolve. In the course of the project, the following topics will be explored in detail: (i) the synthesis of suitable shells for chemically active swarm robots, both soft (with a flexible membrane) and hard (porous solid shells); (ii) the mechanisms of molecular transport into and out of such shells and means of its active control; (iii) chemical reaction kinetics in spatially complex compartmental structures within the shells; (iv) collective behaviour of chemical swarm robots and their response to external stimuli. The project will be carried out by a multi-disciplinary team of enthusiastic young researchers and the concepts and technologies developed in course of the project, as well as the advancements in the fundamental understanding of the behaviour of “chemical robots” and their functional sub-systems, will open up new opportunities in diverse areas including next-generation distributed chemical processing, synthesis and delivery of personalised medicines, recovery of valuable chemicals from dilute resources, environmental clean-up, and others.
