Anyone building a robot dog? I am looking for Servo's to build one that will work with ARC...

If you get a prototype working - I’d recommend reaching out to ezrobot and see if they’d take on manufacturing. Last I spoke with them, they’re starting to focus on diy market a bit
I guess the one off the self D435 on the A1 doesn’t compete with the 5 stereo cameras on BD
what amazes me is you can buy a cheap TOF laser sensor for $10 so putting 1 on each leg isn’t exactly going to break the budget of a $10K dog.
I'm guessing the Spot's front maps a wide area with much more detail (2 depth sensors).
Spot can climb down using a single 3d sensor so I believe the difference is their software and expertise. You can cut corners and costs but in the end the software is the key.
I am watching this project at the moment as it uses the Moteus controller but uses cheap 8308 BLDC's That puts the project in more of the grasp of the general consumer. If we don't use the expensive and heavy motors and go with 12 8308 ($67 on Aliexpress = 804), 12 moteus ($84 =1008) FOC, a canbus usb ($110) a PDU ($150)and use a lightweight X86 computer ($100) we should be able to come in around 3K with a couple of sensors. https://hackaday.io/project/176726-stanley-the-capstan-based-quadruped
Damian Lickindorf is awesome...I really dig his robots!!
Robin Fjord Dog is a MIT clone and this is very cool. Also uses Moteus controller and AK10-9 Motors but at $700 each ummm https://hackaday.io/project/176487-k3lso-quadruped
Yap...pretty awesome but also super high end!!
