Wall-E

Not really but that's how i like calling it :)

Soooo, clearly this robot thing is inspired by the cute one in WAll-E film but without the same body, hands or wheels. In fact, the only common thing is the 2 big eyes

My initial idea was to make a cool toy for "deskers" ( office workers), imagine having something keeps on running on your work desk in random directions, sounds cool !! doesn't it ?

What this Wall E can really do ?

I also integrated a Nrf24l01 so it's able to be controlled wirelessly.

Obstacle avoidance

It can "see" if there is any thing standing on its way by continuously checking the Ultra sonic sensor

Table edge detection

Same thing happens here, :)) Wall-e is able to go around the table without falling off. Here i used a infrared sensor, so instead of generating sound wave and measure the time it bounces back, this sensor uses infrared light.

Radio control

I also integrated a Nrf24l01 so it's able to be controlled wirelessly.

Light sensor

There was still a plenty of space on the Pcb, so i decided to add a Photoresistor and a RGB led, who knows maybe that will be helpfull !!

Pcb base

To keep things as small as posible, i made a good use of the Pcb, not just to place traces but also make it the frame to attach other components onto.
