As briefly mentioned in my last post, my next project is an autonomous quadcopter. That is, a four-rotored flying robot.

After a couple of weeks of waiting around, I've got all the parts I've ordered so far: a basic aluminium chasis from MikroKopter, four 1040Kv/14A brushless motors ...

I found an old RC car - the kind of thing you get for £5 from Argos - lying in my cupboard, mostly untouched since I got it as a birthday present. Still, it has wheels and motors, what more could you ask for?

I proceeded to rip out all its electronics ...

I've finally got around to writing up this project! What you see above is a small robot with a gooey ARM Cortex-M3 STM32 core, a teensy embedded camera from SparkFun, an OLED and an LCD screen, three LiPo batteries, some modified servos and a one-piece (unibody!) aluminium case. The ...

This is my first prototype robot. A friend and I got together and he taped stuff to cardboard while I connected wires up and then we wrote a basic program and the prototype drove!

This version literally just drives forward until the ultrasonic sensor detects an obstacle, then it turns ...

I've finished the lightbar controller!

This device analyses the music it picks up via the electret microphone, then flashes the LEDs in time to the music. It's encased in the box SparkFun sent me the microphones in, since the box was just begging to be used as a ...

I'm having a play with robotics stuff now, and one of the first steps was to get something moving.

I ordered some cheapo servos from ServoShop UK and had a play, they work fine.

However, to use them as easy-to-drive motors for wheels and stuff, you need to modify ...
