With shifts in Mars Sample Return planning, in-situ sampling and analysis on the Martian surface has become a key near-term pathway for planetary geoscience, making advanced robotic sampling capabilities ever more critical. Hot spring silica sinters \u2014 among the highest-priority astrobiological targets for preserving biosignatures of ancient microbial life \u2014 are inherently fragile: brittle, layered, and texturally complex. Excessive gripping force crushes delicate laminae and destroys critical contextual information and biosignatures, while insufficient force drops and shatters samples. Gentle robotic manipulation \u2014 achieving both an appropriate grasp configuration and a suitable force \u2014 is therefore essential. Yet no existing robotic system or manipulation algorithm has been designed for gentle handling of geological samples, let alone under planetary-surface conditions of vacuum, thermal cycling, and communication delays that preclude real-time teleoperation.<br>This PhD project will develop robotic manipulation systems and learning-based autonomy for gentle, low-damage handling of fragile geological samples toward planetary exploration. The project spans three complementary directions \u2014 sensorised end-effectors with tactile sensing; integration into a mobile, rover-style sampling system with the perception and approach this requires; and learning-based control and autonomy \u2014 and the precise focus will be scoped with the supervisors to suit the candidate&#8217;s background and interests. It brings together emerging robotics and tactile-sensing expertise in the School of Electrical Engineering, Computing and Mathematical Sciences (EECMS) with world-leading planetary sample science, astrobiology, and space-engineering expertise in the School of Earth and Planetary Sciences (EPS) and its Space Science and Technology Centre (SSTC) \u2014 the largest planetary research group in the Southern Hemisphere. The project aligns with Curtin&#8217;s LifeSpringsMars initiative, which connects Western Australia&#8217;s Pilbara geology to Mars exploration with robotics as a key enabling technology.<\/p>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Aim\u00a0\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This project aims to develop robotic manipulation systems and learning-based autonomy for gentle, low-damage geological sampling under planetary-surface conditions \u2014 from sensorised end-effectors through to autonomous sampling behaviour.<\/p>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Objectives&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project spans complementary directions across sensing hardware, the robotic sampling system, and learning-based autonomy;
