We don’t know if [Hanna Yatco] has a good sense of balance or not, but we do know her Arduino does. Her build uses the ubiquitous HC-SR04 SONAR sensor and a servo.

The device turns out to be made of fairly simple items, including a MaxBotix MB7066 sonar sensor, an Arduino Pro Mini, and three small motors encased in silicone.

As it turns out, IrukaTact was constructed using off-the-shelf items like an Arduino Pro Mini hobby board and a sonar sensor from MaxBotix.

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door.
