First of all this is not really a hardware topic, but I love it anyway.
The brain is always way beyond my possibilities at creating.
Very accurate drawing? Maybe, but let’s not go into details!
The guy inside me is very excited. He considered.
How big should it be?
Should I be able to ride it?
Well, this was about 1 year ago.
Now i have made a big step ahead. I finished a second leg. Outta 6.
OK OK, now we’re getting serious.
Here are some wires visible, which the Arduino should evaluate. Maybe too much “skin points”.
I tried a few “skin” types:
The goal was something like, very light, easy to build, but no less inferior, precise and so on.
A try with a zip ties and copper foil / spring.
The best solution was this soft skin made out of foam.
The first idea was something like a robot which is cleaning my photovoltaic panels on the roof.
This giant thing on a 32° tiled roof? Would look impressive.
Now the project is more inspired by the mars rover.
- The aimed velocity is about 4 cm per second.
- Dimensions are almost like Curiosity.
- But I think that legs would be better. (Sure, nothing is easier than 6 wheels, but i try it the natural way. Do you have ever seen an animal with wheels?)
- Photovoltaic panels will be the power source. (Maybe with a wind turbine)
- Every leg has 4 security layers, like end-switches, current sensors, position sensors and a software monitoring.
- A little AI because I would love to delay the signals by 6 min. (One direction)

Some of the ball-bearings with aluminium flanges.
Here we have a prototype of a leg control board with 3 current sensors and 3 H-bridges.

20th of Mai:
I installed three PV panels on the robot as an extra power source. They can be folded up.
Here on earth is a bit more difficult to fold the panels than in space.
I tried to push the panales, but this system is higher and definitly not nice to look at.
Some helping hands 😀
