Introduction: Lego Robot

Picture of Lego Robot

What I tried to create was a fully functional robot with all the needed sensors for autonomous control and movement. The main body is the structural core housing the two main control boxes and the four bases for the legs.

The main body has and ample amount of protection to enable movement on rough terrain with out fear of damage.

The legs can be adjusted to different ground clearance for the body from belly dragging to all the way up to 6 inches.

Each leg can move a little more than 180 degrees around the body.

This looks really awesome! What program did you use to design this?

tdorning (author)3ddementor2014-08-10

Lego digital design it's a free program from Lego you can get it on the Lego website

Cool! Did you build one yourself?

No, I don't have all the pieces needed, its quit a large design. I plan on making a custom fabbed bot with my cnc and an arduino based off this design. The only thing that needs to be finished with a prototype is the gear ratios to the legs so they lift and come down correctly.
