Hasbro R2d2 Hacked With Iotiny

DJ Sures

Skip to comments

This build was in two parts. The original build was hacked live at Comic Expo in Calgary Alberta with an EZ-B v3 in 2012. It was a fun hack, because I performed the hack live, where people could watch on a stage. The second hack was in 2017, where we replaced the EZ-B v3 with an IoTiny. 

The recent hack now has the following...

- Powered by an EZ-B IoTiny
- Video and vision recognition with a EZ-B v4 Camera
- Extended the camera cable with a EZ-B v4 Camera Extension Cable (60cm)
- LED animation using a 18 RGB LED PCB
- Reusing the existing motors with a 2.5 Amp Motor Controller
- Powered by a LiPo Robot Battery 7.4v 1300mAh and a LiPo Battery Harness
- Servos for the camera and dome are HDD Servo

Here's the video of the original hack from 2012 with the EZ-B v3 at Comic Expo...

Upgrade to ARC Pro

Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.

That looks like fun, I'm going to have to watch those vids!
I am planning this hack.  Do you have any internal pics of the hack?  Did you remove the existing control board?  How did you attach the servo for the dome?  Would you mind posting any photos?
Hi @mstephens_42,

I'm not DJ but I can certainly provide my personal experience with this R2D2 toy robot. I'm certain there are a few others that can provide some info as well, as a few of us here in the community have tackled this hack.

I have some pics of the internals but I'll have to create a "Robot" project on here soon to share them. I believe all of us have gutted the control board in order to fit our own control electronics. I actually kept the existing motor in the dome and controlled it with an H-Bridge. In order to get the position you can read the on board infrared encoder sensors.

An alternate method is to steal some servo electronics to attach to the motor but you will have to replace the potentiometer with resistors or find a clever way to mount it to get the head position. 

Otherwise, I'm sure DJ will share how he did it.

If you'd like to see the raw footage of me hacking my R2D2 interactive toy, check out the live hack I did a few months ago:

Thanks so much.  I will be watching this and hacking tonight!   Can you post the project code?
