A robotics lab that studies operation assistance for electric wheelchairs and the search for radiation sources.
AboutAbout the lab
Operation assistance for riders and the search for radiation sources
The lab of Associate Professor Yusuke Tamura at the Graduate School of Engineering has studied operation assistance for personal mobility such as electric wheelchairs, and the search for radiation sources by mobile robots.
In personal mobility, the lab aimed to achieve operation assistance that estimates the rider's intent without undermining the rider's sense of agency.
In its radiation source research, the lab developed a method that uses a mobile robot equipped with a gamma-ray detector to estimate the locations of concealed radiation sources.
Key terms
- Personal mobility
- Small vehicles that people ride to get around, including electric wheelchairs
- Sense of agency
- The feeling that one is moving one's own body or a machine by one's own will
- Inverse reinforcement learning
- A machine learning method that estimates the reward function underlying an expert's behavior from records of the expert's operations
ResearchResearch themes
The lab has studied personal mobility vehicles that people ride, and mobile robots that move around within an environment. So far, it has studied operation assistance that follows the rider's intent, and the estimation of the locations of radiation sources that are hidden from view.
*Illustrative imageOperation Assistance for Personal Mobility
The lab aimed at operation assistance that generates motions in line with the rider's intent without undermining the sense of agency. It developed a system that estimates a reward function by inverse reinforcement learning from the driving histories of expert users operating electric wheelchairs, and then generates optimal motions by Q-learning.
*Illustrative imageSearching for Concealed Radiation Sources
The lab developed a method that uses a mobile robot equipped with a gamma-ray detector to estimate regions where a radiation source is likely to be present. By correcting the measurement results to account for the shielding effect of structures, it made it possible to estimate the location of a radiation source even when shielding objects are present.
