Cover image for 🐈‍⬛Check Out Catbot's New Leg!

This is fun. I absolutely must share.

So I recently created a desktop pet, called Catbot. Catbot is voice activated and has memory in an obsidian vault that it shares with models of choice as needed. Catbot is a harness that feels like a pet. I quickly built Catbot a body using AI and was excited to see the result was a furry creature with a robotic leg, which I had asked for. This worked for messing around and building Catbot to start. Here are some images I generated with ai in a previous week, just to catch you up to speed:

awkward rendering, but pretty on point — Awkward initial rendering needing refinement

high level technical drawing — A high level mock technical drawing generated by Gemini I used to generate Catbot’s original body

Catbot's first 3D body — Original Catbot appearance.

But that badly represented robotic pet leg was getting on my nerves. I knew it had to be better. In the back of my head I was like you know what, it needs a way better leg. I let it fester in my head for a while. Then finally, I couldn’t take it anymore. The next moment of free time I sat down and drew up what I thought a robotic pet leg might look like. I drew this quickly, in about 15 minutes or so. I was happy with the overall idea, and believed it made sense. Here is my drawing:

After creating the drawing, I knew that I had to have multiple views to have enough data for ai to create a working prototype. I gave my drawing to Gemini using the following prompt:

“I created this robotic cat leg and I need some good technical drawings of top, side view, front view and back. Can you make me a good technical drawing I can use to share my idea? “

And having luck previously with a different type of schematic (the original Catbot) I knew that this would at least produce something marginally workable. I was absolutely blown away by the mock schematic it produced for me. It is freaking beautiful, exactly what I wanted!

Really awesome robotic leg schematic for Catbot — Nice looking technical drawing by Gemini.

I then gave the schematic with a detailed description to opus for creation using existing Catbot architecture, (using three.js) to create the fantastic leg for me. It did a pretty good job!

I’ve added a video so you can see an interaction with Catbot. It’s entertaining until it frustrates you. Work in progress for sure. LOL. It was difficult to get Catbot’s opintion of it’s new leg:

Catbot is a brat. Do not give your AI pet sass. (You know, unless you can deal with it.) 😂

And let’s not forget where we started:
