I followed your development steps and wanted congrats for your works and sharing’s. When you published the repository about CatMini I decided to test and made my own 3D printed frame and electronics because the biomimetics of cat appeared to me a good model too. Here is a short video of my version “Spring”, hope you will enjoy.
My hobby is also link to robotic applications and I did some robots of my own mainly focusing on alternative way of moving / interacting https://www.facebook.com/versatilerobot and try to share this passion to young's by involve into a robotic French association "Caliban" https://www.facebook.com/AssoCaliban/
I look forward seeing your next developments
Because it looks hard find servo output shaft tooth dimensions I extrapolated by measurements. Attached is a drawing I did in case it would interest some of you. However, it may be good to distort it a little to get a best printing quality.
Here is a small improvement done on the thighs made by 3D printing including the splines of the Servo output shaft MG91 and wire attachment. It is replacing the cut PCB, servo horn, screws and cable ties.
Looks good and more esthetic.
I also admire the springs and I love the clickity-clack of the feet.
Yes indeed there is some problem with the shape of the ultrasonic ranger SR04 when you want hide the electronics.. I had to deal with this constraint and it made the head more square . Thus i worked on the design to make it more cute. It is printed in SLS. Thank you for your kind words ;-)
Hi, Congrats on your build!
I didn't expect a square head can be so cute. It's like a model jumping out from MineCraft. It's also smart to add springs on the feet to achieve similar shock absorption effect. I'm going to share it on my Twitter. 😆
