These days I am so interested in Toio by Sony for my research.

So I want to make something with them.

小さなキューブ型ロボットトイ・toio（トイオ）

Here is an amazing demo by Ryo at CHI conference.

HapticBots: Distributed Encountered-type Haptics for VR with Multiple Shape-changing Mobile Robots

Toio has wheels, 6 axis accelerometer and a magnet sensor.

Here is an example to distinguish stuff by magnet sensor.

My idea

I want to control several Toios with my gesture to describe some shapes with gestures. So I may combine Toio with ESP32 and battery to detect the gesture and to control each Toios.

By voice?

Here is my new sketch for this project.
