Video: Creating an ATtiny robot family

A Maker by the name of “shlonkin” has created a number of mini autonomous vehicles capable of perceiving the world with sensors and adjusting their behavior accordingly.

According to HackADay’s Brian Benchoff, all the ‘bots are powered by Atmel’s versatile ATtiny85¬†microcontroller (MCU).

In addition, the uber-mini ‘bots are equipped with a small battery, two motors, at least one phototransistor and an LED.

“One robot has left and right eyes pointing down, and can act as a line follower. Another has a group of LEDs around its body, allowing it to signal other bots in all directions,” Benchoff explained.

“The goal of the project is to create a whole series of these tiny robots capable of interacting with the environment and each other.”
