Real-Time Geometric-Registration-Based Precision Localization for Autonomous Docking in Unstructured Factory Environment

Sebastian Fernando Chinchilla Gutierrez, Manaru Watanabe, Masahiro Ooyama, Takayuki Yamada, Tomoaki Yamada, Naoto Toshiki +4
ICRA 2026poster

In factory distribution processes, autonomous mobile robots must dock precisely at base stations. However, this task is challenging due to the dynamic and unstructured nature of factory environments, as well as the sparse point clouds caused by sensor occlusions and distance limitations. To address …

Concept and Prototype Development of Adaptive Touch Walking Support Robot for Maximizing Human Physical Potential

Junya Terayama, Ankit A. Ravankar, Jose Victorio Salazar Luces, Seyed Amir Tafrishi, Yasuhisa Hirata
RA-L 2024

We propose a new walking support robot concept, “Nimbus Guardian,” designed to enhance the mobility of both healthy and frail elderly individuals who can walk independently. The proposed robot differs from traditional walker-type or cane-type aids by offering adaptive, minimal touch support based on

A Novel Assistive Controller Based on Differential Geometry for Users of the Differential-Drive Wheeled Mobile Robots

Seyed Amir Tafrishi, Ankit A. Ravankar, Jose Victorio Salazar Luces, Yasuhisa Hirata
ICRA 2022poster

Certain wheeled mobile robots e.g., electric wheelchairs, can operate through indirect joystick controls from users. Correct steering angle becomes essential when the user should determine the vehicle direction and velocity, in particular for differential wheeled vehicles since the vehicle velocity…
