Reply to comment by jjayzx in Carnegie Mellon researchers claim they have used new AI techniques to train much cheaper robot dogs (approx $6,000 cost) to reproduce the advanced functionality of the Boston Dynamics Spot robot. by lughnasadh

SpotMicro isn’t very… agile. But it’s like $15 per hobby actuator and relatively a good start for people who want to get into robotics.

I think once BDLC actuators get cheaper then there will be much more adoption in the space. BDLCs cost like 200-400 per each and these dogs have 12. SpotMicro and it’s variations can be anywhere from 500-1000 while a larger DIY BD size dog with more advanced sensors and jetson nano can cost $10,000+

Can get the servos for $20 for a 4 pack and under $30 for 6, when I was checking earlier. Hoping better software or something comes along and makes them better in the mean time. If not, still something to tinker with for the time being.

Which ones are you looking it? There’s some spot micro variations too.

I haven't chosen the specific circuitry yet and have been just printing the body but none of the board mounts. The body is the one with reinforced shoulders, seems to be a newer build and fixes some issues.

Yea I have the one made by Adham and Maurice which actually uses ROS. Got pretty far but still stuck on debugging serial communication with the Rpi and teensy controller.

I have rpi and esp32 sitting around, I just didn't deep dive yet to see what route I wanna go. I was just getting most of body printed for now as I still have to finish another project I've been working on.

There’s one with the ESP 32 that seems much easier to build tho

Way cheaper to buy a unitree and go from there

Yea unitree is. But if you’re learning, unitree is just a shortcut.

Haha yeah it is. But their hardware is just so damn cheap and great quality!
