hello, and welcome to my corner of the internet.
I’m Ziyi Li.
I build little worlds
from the one we live in.
I use reconstruction to preserve places and moments, and to build environments where robots can learn.
Start with a moving scene01 / reconstructing a little movement
Sparse-view 4D reconstruction
I wanted to understand how a few views could hold onto a moving scene.

learning to care, in familiar spaces
More than
reconstruction.
I reconstruct a laboratory and an older adult’s home so robots can practise the everyday tasks of caring for older people.
Real Sim Real
The goal: robots that can offer older people practical, attentive help at home.
01 At the bedside
Everyday care for older people.
G1 takes the cup after a drink and gently draws up the blanket. I’m exploring how robots could help older people with everyday care and comfort.

making time for companionship
A game,
shared.
I want robots to offer older people companionship, too—sharing familiar games and making time for play.
02 A game together
Time spent together.
A relaxed rally with an older player in a wheelchair. G1 returns the ball within reach, making the game a moment of companionship at the player’s own pace.

Keep scrolling to follow the rally.
