A friend gave me his old Lego Spybotics robot, however, the programming environment that goes along with it is a bit too orientated to the younger user.

So why not control it using an Arduino?

Step 1: Open Up!

In order to get this robot moving, we need to borrow its motors.

There are two DC motors in the robot. This is great, because we can control them independently, allowing forward, backwards and turning motion.

Start by unscrewing the lid off the top of the robot. The screws are located on the bottom. Four by the battery bay and two in the front.

Locate the two DC motors near the back, then switch on your soldering iron.

De-solder the motors from the contact points. This can be done by simply applying a little upwards pressure on the motor whilst heating the solder - the contact should come unstuck.

Once detached, remove the motors by just wiggling them out. Solder some wire (about 10cm or more) onto the contacts, taking care not to damage the rather fragile motor contacts.

Before putting the motors back, cover the original contacts with some electrician's tape,  just to isolate the old board from any current we send the motors' way. Then just slot the motors back in.

There are two buttons on the top of the lid. Pull them out. This will create two holes. Route the cables through those holes and affix the lid back on.
I've still got my one, those have light sensors and even a bump sensor normaly in the front those could be used with arduino also, maybe I should mod my one! hmmm where did I leave it....
