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

Servo Speed
by Synthiam
Adjust servo/PWM speed (0-20) between two positions to quickly experiment and tune motion; select board/port; settings aren't saved.
Just had to throw this one in here...its so well filmed, sometimes you'd almost think it is CGI!!
Wow. I want one. Just think owning a dog like this and not needing a pooper scooper.
I want one as well, I just lack the $70,000 needed to buy it.
@Nink, sell the house to pay for it. You'd be one of the coolest homeless guys around. LOL.
If I didn’t have a wife and kids... Maybe we should just short GameStop. You go first.
Adding battery info, because if we order motors to test with, we need them to run!
If your project is large like a dog..make sure you pay attention to the voltage requirements for that motor because you will get better performance with max volts. As an example...drone motors are using standard hobby lipo batteries..but depending on the size of the motor voltage can go way up. Try to match the battery for your motors.
Standard lipo battery voltage for drone motors: 3S is 11V 6S is 22V 12S is 44.4 V 14S is 48V
How long your robot runs will depend on how many amps you can feed it. Remember If you have a 1 amp/hour battery (1000mil/amps) you can run a 1 amp motor (no load) for about an hour. If you put that motor under load and it pulls 2 amps, the battery would only last for 1/2 hour and so on. On a dog if you had 12 motors, pulling 1 amp at idle, that's 12 amps/hr. So if you had a 12 amp/hr battery you could run it for an hour. But we know the dog will be jumping running and the current draw will be different every time you take it out. Just get the max Amp battery you can afford...they get pricey the larger you go!
You can also get 2 batteries and combine them in parallel or in series for more volts/or more amps whichever you need.
Something to consider is a voltage step down to get more amps out of a high voltage battery. It's usually easier to find a high voltage battery than high amp batter. If you need 12v but use a 24v battery, you'll double the amperage and runtime. But be sure to find a digital switching power supply that can do it.
Here's a 10amp 24 to 12 one: https://www.daygreen.com/collections/24v-to-12v-13-8v/products/24v-to-12v-10a-120w-dc-dc-step-down-converter-voltage-regulator
And 30 amp: https://www.daygreen.com/collections/24v-to-12v-13-8v/products/24v-to-13-8v-30a-414w-dc-dc-step-down-converter-voltage-regulator-1
What? 30A ?That is awesome, I was always putting 3 or 4 12 volt batteries together in Parallel to get higher Amps, longer run time on large wheeled bot,what a wasting of batteries and trying to charge them all, I should have just asked you last year how to do this easier!
