A measurement lab working on balloon robots, tactile displays, and fluctuation analysis.

AboutAbout the lab
Using a variety of measurement technologies to make people's lives more comfortable
The Uchida Lab researches and develops tools for a comfortable life by applying a variety of measurement technologies.
Its research themes are balloon robots that swim through the air, fluctuation analysis to assess proficiency in a movement, and biological measurement developed from tactile display technology.
On the lab's website, it invites interested students to come and visit the lab.
Key terms
- Balloon robot
- A robot with a helium-filled balloon body that floats and swims through the air. In this lab, it is shaped like a fish.
- Tactile display
- Technology that conveys information to people through the sense of touch rather than vision or hearing.
- Fluctuation analysis
- An analysis that examines how time-series data obtained during movement varies, and uses it to evaluate things such as proficiency in a movement.
- Deep reinforcement learning
- A learning method in which a computer finds good actions on its own through repeated trials.
ResearchResearch themes
This lab's theme is using measurement technology to create tools that let people live comfortably. Its research is divided among groups for balloon robots, fluctuation analysis, and biological measurement.
*Illustrative imageFish-shaped balloon robots that swim through the air
The lab makes fish-shaped robots that float on helium gas swim through the air by imitating the movements of a fish's fins. Because the robots are easily affected by air currents, the lab is trying a control method in which they acquire swimming motions autonomously through deep reinforcement learning.
*Illustrative imageMeasuring proficiency in a movement through fluctuations
The lab applies fluctuation analysis to time-series data from experiments that combine a synchronized tapping task with a pen-stroke task, and uses it to evaluate proficiency in pen-stroke movements. It is also considering how to evaluate proficiency in pick-and-place movements.
*Illustrative imageBiological measurement that conveys information through touch
Building on tactile display technology, the lab studies new ways of conveying information that do not rely on vision or hearing. It applies vibration stimuli to the neck and upper limbs to intervene in the information entering the central nervous system, aiming to solve physical problems.
