I have recently become interested in hacking toys as is evidenced by the numerous Instructables I have posted about hacking the Spy Video Trakr: I created this Instructable specifically to enter it into the Toy Challenge Contest. Go to and click the vote button (you may have to scroll through a few pages to find it). Please vote for this Instructable, "Make a Grabber Bot Out of Legos, Snap Circuits, and the Spy Video Trakr," in the Toy Challenge Contest. The remote control unit has control levers to drive the robot, a speaker and color video display so you can hear the audio picked up by the microphone and display the video transmitted by the camera, and several function buttons that can be used to control additional program functions of user designed programs. The Spy Video Trakr is a remote controlled robot equipped with a microphone and color video camera, speaker, a near infrared LED for night vision, an SD memory card slot for recording audio/video and 8MB of on board memory for storing downloadable and user designed programs. Finally I'll provide you with the C language code that you can compile and install on the Trakr to operate the remote controlled grabber bot. The Lego grabber arm will need to be mounted on the Trakr so, I'll show you how to attach a payload deck made out of Legos. With the jumper pins installed I'll show you how to tap into the 9 volt power supply of the trakr and make connection cables to connect to Snap Circuits and the Lego motor. Then I will demonstrate how to open up the Trakr, attach jumper pins to the GPIO connections on the circuit board of the Trakr. Next I’ll explain how to compile a simple program and install it on the Trakr and then run this simple program. ![]() I will demonstrate how to download and install the C language compiler for the Trakr. In this instructable I will demonstrate how to use Legos, Snap Circuits, and the Spy Video Trakr to create a remote controlled grabber bot.
