Let's Make Robots!


Sky dives

Skydiver can move on the ground or be lifted on a weather balloon. During its whole mission the robot measures the background  resp. cosmic radiation and capture videos, which are stored on a micro SD card.

The body is a plastic lunch box, quite stabile and easy to drill. I have replaced the previous track platform by a RC buggy chassis:

The Geiger counter clicks will be transmitted by a hacked 0.5W walkie-talkie:

On its top of the robot will be a release mechanism mounted to seperate the robot from the weather ballon when the required altitude is reached (timer):

The parachute is made from Nylon and has a diameter of 1.5m:

The camera is mounted above the ping. The ultrasonic sensor and camera point downward during descent. I am planning to use two retrorockets, mounted on the robot, to decelerate the fall at the last few meters. The rockets are triggered by the ping. If the surface is reached (and the robot still not damaged), the parachute will be decoupled and ping and camera horizontal aligned before the robot continue its journey on the ground.

A few km without buildings between :)

Sweeet! Where do you get that epoxy sheet? 

I get the epoxy sheet from a local store at the Beijing Road :)

That's a brave little bot. I hope the parachute will open when he makes his first jump.


Maybe some test runs with a crash test lunchbox. You could fill it with something that will indicate how much force is received on landing. Something cool and high-tech. Like eggs. ; j

Agreed, nuumio! May I suggest redundant parachutes for the stalwart Skydiver? I'd hate to see that pretty carbon fiber panel turn to pencil lead dust.
