In this Instructable, I will attempt to show you how I converted a 1980's Tonka push toy into a working RC robot. Since the robot was assembled prior to the thought of creating an instructable, I hope this serves as a guideline when thinking of creating your own.
Step 1: Parts
When converting a Tonka truck, getting parts isn't the difficult task but locating the actual metal truck will definitely be a challenge. I had the best luck on Craigslist. I got four for a deal and started with the front loader.
Step 2: My Part List
Tires- the rear tires are bigger than the front because the batteries are held in the back.
The rear tires

The front tires at Traxxas tires.

Motor driver- sabretooth dial 12a driver for rc
Battery- I'm using two six volt maintenance free rechargeable sealed lead acid batteries. That i ran in series to create twelve volts. You can find them at Home Depot.
Motor- there is one motor in each wheel.

Actuators- I am using Firgelli actuators. www.firgelli.com
I'm using two-100mm actuators and one 50mm actuators all 100:1 gear ratio.
Step 3: Solar Hood
I made this cover out of regular steel. Attached two six volt solar panels (ran in series to create 12 volts), connected to a 12 volt battery minder with desulfator. Note: the solar panels does not keep the batteries fully charged during use but does increase run time significantly).
Step 4: Ending
Sorry I couldn't provide step-by-step instructions. But honestly the object to making a robot is creating your own. So hopefully this can be of use as a guideline to creating your own robot. I hope this really does help someone and you guys like it. Also I have a few YouTube videos of me running them... I hope you enjoy!
