About
Ryosuke Tokoi is a robotics researcher focused on bio-inspired mechanisms for extreme environment exploration, particularly for lunar and under-ice applications. His primary research areas include earthworm-type locomotion, flexible propulsion units, and autonomous drilling systems for planetary and polar subsurface investigation. Tokoi’s major contribution lies in developing novel braid-based propulsion units that can both propel and grasp, enabling robots to drill into ice and regolith while maintaining stability in low-gravity or submerged conditions. His 2021 paper on a propulsion unit control method for visualizing the grasping state of an earthworm-type lunar excavation robot has garnered 10 citations, reflecting its foundational role in this niche field. He has also advanced ice-drilling technology for under-sea-ice surveys, with experimental validations in actual Arctic-like conditions. Tokoi’s work addresses critical gaps in autonomous exploration—enabling longer-range, more adaptable robots for climate research and planetary science. His achievements include the development of a flexible propulsion unit using a braid mechanism, which demonstrates improved grasping characteristics for lunar exploration robots. Tokoi’s research is paving the way for next-generation robots that can autonomously penetrate and sample some of the most inaccessible environments on Earth and beyond.
