Tri-Colored Mech Robot

This is my tri-colored mech robot! His name is Oscar. I've been inspired by photos of other rendered robots, and I figured to give it a try using Inventor!

As someone who as used Inventor for two years, this project led me to discover more features of the Inventor program. Overall, this project has been one of my personal favorites.

Here, I'll walk you through the steps I took into making Oscar.

I used Inventor CAD for this project.

I started with Oscar's legs. I used reference from toys and my own imagination for the structure, millimeters for units. I then made the hip structure while considering joint space for the previously made legs. The feet were the simplest of all to make - only took one sketch, it was just a matter of extruding correctly. I opened a blank assembly and place all the parts together using a basic opposing mate - no joints just yet.

I showcase the arms and torso in line with the hip hinge. I eyeballed some measurements for the torso as I wanted to have fun with it. The arms have a bit of detail, so I had more opportunity for coloring.

I added rotational ball joints on Oscar's legs and some other constraints for his arms. Here, I display the leg moving in response of pulling one of the feet.

I decided to go with vivid colors. Out of the variety of color schemes I tried, I felt the following best represented Oscar: pink, yellow, and cyan/blue.

Oscar is now finished and ready to 3D print!
