Abstract
This paper details the design and construction of a biologically inspired nanorover prototype for exploring Mars. Although all Martian exploration vehicles to date have been wheeled, a six legged design was selected for this rover so as to improve its trafficability across rough terrains, since the main focus of this project was miniaturisation, with a goal of building a rover which weighed less than 1kg. To this end, shape memory alloy actuators were used instead of conventional rotary motors, due to their small size and mass, and carbon fibre was used as the main construction material. The rover was analysed using a combination of empirical results and computer simulation, in particular a simulation tool being developed at the University of Surrey called the Legged Performance and Traction Predicting Tool (LPTPT), with results suggesting that the design could be the basis of a successful planetary exploration vehicle.
