Biomorphic wind sensing

Integrating MEMS and aVLSI into robotics

This EPSRC funded project combines microelectromechanical systems (MEMS), analogue very large scale integration electronic circuit design (aVLSI), and neural simulation for controlling robots to develop a wind-sensing system based on insect hair cells. It will be implemented in a fully integrated MEMS/aVLSI chip and interfaced to a robot to test in controlling behaviours such as course stabilisation and upwind flight. Important issues to be addressed include: the most effective mechanical designs and the optimal sensor layouts for the task; the use of short-term synaptic plasticity in hardware neural circuits as a means of adaptive preprocessing of MEMS sensor output; development of hardware and software interfaces between aVLSI chips and digital circuits and neural simulations; and the design of insect inspired neural controllers for combining different sensory inputs and responding robustly in complex environments such as turbulent windflow.
