4-Legged robot - I don't know where to start

thinklab

Hello! I want to create an animated 3d model of robot-dog, which will contain:

1. 4 legs with 3 DOF (3 servo+accelerometer in each);
2. balancing system based on data from accelerometers;
3. 1 type of walk;
4. walking on hard random terrain;

The only thing I have is STL 3d-models of legs and servo. I can import a STL into example sketch from ToxicLibs and spin it.
I know that I have to solve IK-problem. I found a solution for 2d and want to rewrite it to 3d. Three vectors in space will be formed under the influence of the surface over which they move. How I can to glue an STL of, for example, ankle to appropriate vector?
What I have to do next?

I am confused with most of the language you just used. I have no idea what STL, DOF, servo, STL, ToxicLibs, IK is etc.

For the uneven ground I would use noise() and a unchanging x/z grid. You NEED to use PShapes , otherwise the frameRate is shit. From there you have to rotate/ translate the PShapes into the positions you want at any given time. You need a good graphics card on you computer otherwise it won't run.

This question was from May. Is an answer still needed here? Why post what you did on such an old thread?

because I 1.) Didn't see that it was posted in May and 2.) nobody answered! And I've done almost the same thing so I can help :)

@heyilovepie: Did you do the robot in hardware or "only" virtual on the screen?
