Outdoor RC car
I always wanted to make this thing :D :D
It's not big thing, just that I didn't find anywhere an rc car that can pass big obstacles, but in the same time to have speed, so I made one myself.
There are 2 gear boxes, each one for 2 independent motors. I made the wood frame when I was at my grandparents, in a holiday. Unfortunately, I don't have photos of the different components, just the car as one, so it'll be difficult to see some things.
I took the wheels from an rc car. These are the biggest wheels I could find (5/10 cm) The battery holder is from another rc car and the radio receiver from the same car like the battery holder. As you can see I used a lot of hot glue, althought it is not so resistant, I couldn't make holes for screws, just the gearboxes are screwed.
My first thought was to make all to get in the space between the wheels, but I realized that the frame is too big. So the battery holder doesn't fit and, if the car falls over, it stucks :(
The car direction functions on the tank principle, so the radio command is a little tricky. I took it from an old rc car I have hacked.
UPDATE 1: I put another battery holder of 2 batteries, the car couldn't climb a rock, now it can.
As to Chow's suggestion, who I thank again to, I made this radio command, using the old one and 4 push buttons.
This is it, uncovered:
This are the buttons:
Each button controls the direction of one side of the car.
This is the finished radio command, back view:
