Study on SMA driven hopper design for planetary exploration
Nihon Kikai Gakkai ronbunshu, 2018 This paper studies the feasibility of a hopper for planetary exploration rovers. The proposed hopper is designed based on shape memory alloy(SMA) actuators, because SMA actuators are light in mass compared with traditional electric motors.

Robotics in Ionizing Radiation Environments: Vulnerabilities, Hardening, and Future Directions
Advanced Robotics Research, EarlyView.Radiation exposure causes cumulative degradation in robotic sensors, actuators, and electronic logic, often leading to undetected failures. This study maps component vulnerabilities, evaluates hardening and shielding strategies, and identifies testing gaps that must be addressed to enable next‐generation radiation‐tolerant robotic systems.

The Dilemma Diagnoser Approach and its Application to the Fault-Tolerant Control of Planetary Exploration Rovers [PDF]
, 2013 Most of the fault-tolerant control strategies found in the literature assume conclusive diagnosis, i.e. the current fault mode of the plant is well-known. Although, speculative diagnosis can be a more realistic approach while noise corrupted measurements

Taxonomy, Systems Review and Performance Metrics of Planetary Exploration Rovers [PDF]
, 2014 A taxonomy of planetary exploration rovers is presented, followed by a review of systems used in missions and in an experimental phase. The baseline design emerges as four or six wheels, rocker-bogie based passive suspension and all wheel driving ...
