SapoBot

SapoBot is a robot that wonders through spaces avoiding obstacles, follow walls and lines. To change between behaviours one only need to press the shell, and when the bot detects a collision triggers a frog sound. This project was commissioned by Sapo (frog in Portuguese).

This bots were made with a Farrusco chassis and Motoruino and once again with the great IDMind hardware and electronics skills, all the credits for the eyes mechanics and all the rest of the hardware upgrade goes to them.

The shell was made by Fernando and Margarida Antunes, don’t forget to check their amazing art work at http://margaridantunes.weebly.com.

This is a Farrusco on steroids!! Only the pins 0 and 1 for serial communication are free, all the other pins are taken for a considerable amount of sensors and actuators: 3 infrared sensors to measure distances on the front, 3 infra red sensors facing the ground, a speaker, 1 RGB LED, 1 servo motor, 2 dc motors and 2 bumper micro-switches to detect collisions.

The eyes are meant to give some human expression to the bot, they turn organically to both sides according the direction that the robot takes.

We coded an application in Processing to check all the sensors and actuators, allowing to save settings on the microcontroller EEPROM. This code will be available on Artica’s github soon.

Time to drink some juice :]

And the result is a happy family!
