After two years of planning, assembly finally began:

 

Laser cut steel:

 

 

Motor characteristics:

 

Assembling the "shell":

 

 

 

 

Lots and lots of screws:

 

 

 

Basic structure with integrated motors:

 

 

Shaft specs:

 

Smaller sprocket (on the left) should be welded on, but only on the left side and not the right side.

The bigger sprocket should be fixed with a pin through the shaft (needed for assembly sequence).

Can you show the drive system? It looks like you might be using tracks. Almost looks like the sand crawler in Star Wars.

Whoaaa, awesomeness level over 9000!

Is there a video?

I am planning on making a video, when the project is finished, it is going to be uploaded to this YouTube channel: Electrical and mechanical engineering projects. This project will also be updated with a video and more information about custom electronics.

 

I also made made a very similar robot with tracks as you did. If you need any information you can contatct me directly, since we are from the same country :)

 

I am so jealous!!! I might have to make my own.

I'm gonna join you on the fanclub @nschreiber0813 !

LOL

I love it.

How much do you think it would cost to reproduce?

How much would it cost to purchase your plans/vendor list/advice while building?

Once again, I love it.

Regards,

Martin

 

The total cost of the build was 1000 EUR + battery (500 EUR, 210 pcs of 18650 cells).

Seems like I need to make a tutorial about it.

I will publish all the files I have and write a tutorial in the next couple of weeks/months (hope I find the time).

I like the design very much.It is very simple, yet it looks like something out of a Science-Fiction movie.
