One of my momumental moment when our musculoskeletal legs successfully operated for the first time. He has about 50 motors and motor drivers.
Life long goal
- Make robots safe for both people and robots themselves. Both soft hardware and the compliant controller are necessary.
- I want life-assistant robots to fold laundry, clean the bathtub, change the sheets and do other tedious tasks for me at home...
- Housework needed varies from household to household. The ability of robots to learn from people is necessary.
Preferred Networks
- I reimplemented the Deepmind paper results.
https://tech.preferred.jp/ja/blog/replication-of-emergence-of-locomotion-behaviors-in-rich-environment/ - Tackled Sim-to-Real problem in bipedal locomotion of Table-top sized Humanoid. It turned out to be a very tough problem, especially with high-gear ratio motors. My coworker recently published a paper after 4 years(!).
JSK robotics labratory
- I was sooooo happy that many many humanoid robots surrounded me.
- Did research on the learning-based control on musculoskeletal Humanoid.
Technical Detail of My research
-
I added a hip-soft sensor to Musculoskeletal Legs(MusashiOLegs).
- FSR + soft-foam
- This enables soft contact- with environments. Most humanoids cannot even sit down on a chair with their own body. (There are motors in hip joints.)
Technical Detail of My research
- Self-supervised learning of dynamics model of highly nonlinear robots. And designed its controller using the learned model.
\bm{y}_t = \{\bm{F}_{loadcell},\bm{F}_{hip},\bm{\theta}\}
\bm{u} = \{\Delta\bm{\theta}\}
\bm{y}_{t+1} = f(\bm{x}_t,\bm{u}_t)
\bm{L} = h_{loss}(\bm{y}^{est}, \bm{y}^{ref})\\
\bm{g} = \partial L/\partial \bm{u}^{opt}\\
\bm{u}^{opt} \gets \bm{u}^{opt} - \alpha \bm{g}/\|\bm{g}\|_2
Technical Detail of My research
- Musculoskeletal legs did sit back experiment using learned dynamics model.

TRI
second dream
- I always dream of a future where I go to a restaurant with my favorite cay, drink my favorite wines, and go back to my home with my favorite car in self-driving mode.
- The Audi skysphere concept was the realization of my dream.
skysphere can transform from a sports car to a luxury car.
