Spring by VersatileRobot



Dear Sir,


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

Best regards,




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. 😆

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 ;-)

  • Hey Comrades, So I figured out how to use GoPro with OpenCV. Now my plan is to put the GoPro on the Cat and make it do stuff. However, I can't figure out how to put it properly. In the video below I have just tied it up with a string to observe how the new weight distribution affects the physical behavior of the cat with the current motion planning algorithms. The cat always falls over while walking and trotting, but works reasonably well with crawling-the lower center of gravity while crawling probably makes it more stable. Is there any genius friend out there who could help me design a GoPro mount for a Nybble? Regards, Zaigham Abbas
  • Hey comrades, So you ever wanted to control your cat like a puppet? Well I developed something that might be of some interest to you. Right now I am tracing my fingers and measuring the angle with respect to my thumb. Pose-estimation is too much computationally complex, however, there are definitely some lite-models for pose-estimation that could help. Is anyone familiar with google's media-pipe?
