Topsie is the dog robot (quadruped) that anyone can build. Building it takes no special skills. No 3D printing needed either. No soldering. Just a few hand tools actually. I put it together in about a week. I named it Topsie as a nod to Boston Dynamics Spot. ("Tops" is "Spot" spelled backwards.) Using an EZ-B with Synthiam, I was able to code a walking gate in a couple of hours. It cost me about $300 for the motors (60kg/cm "robot" servos from Amazon) and another $200 for the extruded aluminum. If you were to use PVC pipes instead of aluminum, you would bring the price down to about $300 for the robot. 

Now anyone can build and have his own dog robot!

I will be publishing the build process to YouTube in a few weeks. 

Here is an early photo of Topsie on her stand. Kind of looks like a walking table! l still may print some covers for the legs and torso. Better photos are coming.

Cool, love it. Is that 12 servos in total (3 per leg)?
