So, it’s been a while since I’ve had the screwdrivers and soldering iron out for fun, so figured I’d start a new project and share it with you guys. What I’m working on this time is a toy hack rather than a scratch build, and for this I’ll be using the R2-D2 Interactive Astromech Droid from Hasbro.
For those of you who don’t know, this was released in 2002 and was fully voice controlled (no smart phone or R/C controllers). I purchased this off eBay a couple of years back and after finding out that the voice recognition wasn’t that great (not for me anyway), I was going to do an EZ-Robot conversion similar to what DJ and a few others did... but, as some of you know, I ended up scratch building a full size droid instead so it got packed away and forgot about it.
Recently my girlfriends granddaughter has shown an interest in robotics so I have started helping her out and introducing her to EZ-Robot. While searching for robot bits and peices, I can across the little droid and have set about giving him a new lease of life and make him better than he ever was using a EZ-B v4/2 dev kit and a few sensors etc.
Here goes. Enjoy.

No problem. I think it would be a great fun project to get you started. I hope you go through with it. It’ll be nice having another K-9 project here. I started with little knowledge of robot building but jumped in head first and built a full size K-9 (link below) as my very first EZ-Robot build. It was a fun build and learned a lot.
Good luck.

long fan DJ Sures knows me slightly as well. I have an R2 unit all he does when you tur him on is a few beeps the dome turns a few times and thats it. tried resetting nothing works. I want to do rebuild the R2 unit using your methods. On a budget I have a ultra sonic sensor, Access to a 3d printer but what is your parts list for others to follow in your foot steps?
Hello @harunobumadarame
When I did my live hack, I used the same thing as DJ: IoTIny, EZ-Robot 7.4V Lipo, and the EZ-Robot L298 H-bridge. I also used a small H-bridge for the head rotation motor.
Here's my live hack video if you're interested
*EDit: Ooops I lied I used an EZ-Bv4, but I could have used an IoTiny!
Hello Steve G, can you share your r2d2 project? Thank you and love what you have done and built.
Where did you get that bi color board red and green?
