As future planetary missions evolve from local exploration in the vicinity of the lander (up to a few km) to more regional operations (with a reach beyond tens of km), the need for a safe and efficient traverse will be greater than ever. To address these challenges, the EU FP7 FASTER project [1] has tackled for the past 4 years the Forward Acquisition of(More)
When designing a legged robot a small change in one variable can have a significant effect on a number of the robot's characteristics, meaning that making tradeoffs can be difficult. The algorithm presented in this paper uses biologically inspired optimization techniques to identify the effects of changing various robot design variables and determine if(More)
Despite the increase in autonomous capabilities of mobile robots, planetary exploration rovers are severely limited in their operational paradigms. Current rover operations, especially the traverse operations, involve day to day planning and simulation with human involvement for the estimation of potential dangers faced by the rover. Additionally, due to(More)
Space systems are similar to their terrestrial counterparts in many respects but the main distinction that makes space system unique are due to the harsh and low gravity environment that space systems needs to survive, requirements of system redundancy due to lack of on orbit maintenance or parts replacement and costs associated with those. These put extra(More)
This paper details some of the various robotics projects which have been inspired by the natural world, and which the authors believe will have an impact on the future of robotic space exploration. This includes both hardware-centric projects such as RiSE, and projects which concentrate more on software and control such as Swarm-bots. The authors outline(More)
