ZenBot is a three wheeled robot that will only move when user concentrates enough.
Concentration is measured using NeuroSky Mindwave headgear and send over radio to computer. Computer is used as a control for concentration threshold (Mindwave measures from 0-100) and as a gateway from headgear to Arduino on ZenBot.
As Mindwave uses RF (not Bluetooth as Mindset also from Neurosky) we used same program that controls threshold to send Mindwave dongles values over bluetooth.
Robot stays inside the black area using three line sensors that see when black ends. And for feedback to user one RGB led is used to indicate how hard is user concentrating.
This is joint build by me, Kimmo Karvinen and Tero Karvinen.
