Well these new dogs can only be better than their predecessors...probably worth the 1/2 year wait?!

Looks like this guy built his own version of the MIT robot. https://jpieper.com/2020/11/09/mjbots-november-2020-update/  If you watch his November update video and follow along with his blog you can see his journey, he developed his own motor driver controller board and motors as well.

This time around I ordered (I Hope) one of the developer kits from MJ Bots Figured this would be a good place to start.  supports CAN-FD and can run up to 400W.  About $200 US including shipping. Actual Boards are only $84 if someone else wants to get one but I  figured I needed a motor PSU connectors etc and saves me running around finding parts.   https://mjbots.com

Interesting. The moteus r4.5 controller is quite a bit cheaper than my flipskys FOC controller. Let me know how much torque you get with those motors. I was planning on something quite a bit bigger.

Josh is amazing and has really come a long way and is an excellent engineer and developer.

There is a good video on the moteus dev kit config. USB connect to PC and Python app controls.

Is this the same dog you all talking about? I just read this, they say now anyone with a printer ,500 dollars in parts and something like Raspberry Pi,can build it "Chop"... Dog,Spot

Nice find. Looks like a different dog the original one I posted used off the shelf lynxmothion brackets and servo's but 3D printing could be a lot cheaper. The 20kg PWM servo's are cheap but kind of slow , a guy could die of thirst before the beer arrived.
