Found your great video on Makezine today (congrats on that). I've never heard of Houdini, but I was amazed by the video. I just have one question, can the same setup be used to replay a series of claw positions? Rephrased: can you create a rendered animation in Houdini and have each timestep of the servo data sent to the claw in real time? Could it work if it wasn't in real time (I'm thinking maybe a script or really slowed down animation that can just send it frame by frame automagically)?
I'm pretty sure Houdini will be my next software tool to learn because of your video.
Oh wow, didn't realize it was posted on make! In reply to your question, yes, it is definitely possible, simply by either keyframing the values of the parameters (if you need really detailed control) or some procedural input (noise function, or reaction to something etc), it can put the claw into pre-defined positions.
One thing you may want to consider is servo speed/torque versus the speed of the animation - if it's changing too fast the servo may not be able to keep up. Also, what is "animation" and how heavy is this? Many ways to do it - houdini's not a 3d/effect application - it's a 3d operating system :3 You can definitely create animation of all sorts from characters to collapsing bridges and use that data to drive the arduino, and from there, maybe with a little tinkering, a proton canon
. But I digress.
Let me know if I can help further. My next project is using ADXL335 data, however I'm a little stuck at data acquisition - digital filtering, convolution of signals and all that jazz. Houdini is a great package to learn, and the community here is awesome
