Tutorial to make a bluetooth remote controlled 1980's retro robot, that I named Master Blaster!

I found this robot shell for cheap in china town the other day. It is plastic and cost me $9.99. Its original motion was to walk forward and flash its eyes. Not very exciting...

I added the EZ-B Robot Controller Board and some servos. The DIY robot is now remote control from my computer. You can modify a similar robot to do the same. Here are the steps :)

What You Need
1 x Plastic Robot Shell
1 x EZ-B Robot Controller (www.ez-robot.com)
1 x EZ-Builder software (www.ez-robot.com)
3 x Standard Servos (http://www.hvwtech.com/products_view.asp?ProductID=878)
2 x Modified Servos (http://www.hvwtech.com/products_view.asp?ProductID=877)
1 x Battery Pack (http://www.hvwtech.com/products_view.asp?ProductID=1206)

Tools
Hot Glue Gun
Small Screw Driver Set
Soldering Iron
Dremel

Video
I suggest watching the video first, before looking at the slide show. This will give you an idea of the order of steps. Your robot may be in a different shell, so watching how I build this robot will give you an idea of how to plan ahead. Take your time :)

Step 1: Dismantle Robot Shell

Take robot apart. Use a small screw driver set and dismantle the robot. Be sure to keep screws and all the peices seperate. You'll never know what you may need, so don't throw anything out until you are done.

Step 2: Start Modifying Shell

This shell had a walking motion, so the feed would slide. In order for the feet to slide, there are little hingest at the ankles.

I put screws at the hinge points to hold the feet steady. My robot will be driven by wheels, so i don't want the legs moving at all.

Step 3: Modify Shell With Dremel

The dremel is my favourite tool when building robots.

You'll need to modify the original shell to fit your servos. I use straight cutting bits on my dremel.

I removed the battery holder. And that exposes the insides so i can fit the EZ-B board and batteries after.

Where can i get a cheaper ez-b
djsures (author)  firepup1043 years ago
The ez-b is already priced way below any comparable robot controllers. The project cares more about building robots than making money :)
That stinks cause i am just a 11 year old boy with no money :(

Tell you what! Huge props for being an 11 year old boy wanting to build robots! That is real cool. The expensive part with robotics are the servos actually. Because the robot controller you can re-use. When you get into robot controllers and circuit boards and need servos, then look up the as-12 acoms servo. they are the cheapest around and pretty good quality. it is what i use because i buy them bulk from ebay.
but stll is there a cheaper one from sparkfun

spark fun has a bluetooth robot controller with 9 adc, 14 servo, 20 uart, 20 digital i/o, voice recognition, color recognition, motion recognition, sdk, graphical development gui, and a more?
thanx
