I just have a quick question. What kind of AC/DC adapter should I use? I just want to be sure not to break anything. Right now I am just working off of battery which dies off quickly some times. Thanks!
Wow he's so awesome! I'm fond of robots in fur for some freudian reason I'm sure.
My answer for power supply is quite complicated but simple - I encourage direct battery power. BUT, if you need a power supply, there are digital switching options to choose. Make sure it's enough amperage according to that tutorial I linked to.
Motors are unpredictable for power consumption because they are electro-magnetic and there's a pile of variables that are pretty much unpredictable without a degree in physics
So pick a real high amperage digital switching supply for 6-7v and use it
So for this project that you have a 7.4v 20amp power supply will work just fine... You could probably get away with 10amps, however you should get the 20amp version in case you want to add more servos or use it for another project that does use more servos....
Actually I would go with what @DJ suggests... Grab a bigger 7.4v LIPO from ebay... there are lots rated at 3000mah ~ 5000mah... Servos need power and you can't beat Lipos for being able to supply it...
Ok. Ill go look them up! Thanks so much for everyone's help!
Thanks so much Dj and Richard.
No worries... We don't want to turn your bear into Smokey the Bear.... Have fun....
Lol thanks. I did try a DC 6 volt adapter that I had. It made the servos move a little, but it didn't turn on the actual ez v4.
6V will work if the power supply is rated above 10amps or more.... Remember you need amps to run servos.... voltage between 6V and 8.4V should be ok.... 7.4V is ideal however...
