servos

Hi everyone.
Im new into this arduino programing and i totaly love it!
Im building a realy simple 3 servo hexapod walker. All the building is completed and im able to program it to do different thing for example walk forward, or turn.

I'm working on a small robot that will be using 2 continuous rotation servos that each require 6v to operate. Now my question is should I hook both up to a single 6v power source OR hook both up to a 12v power source OR hook each servo to its own 6v power source? Hope someone can help me, thanks!

Hello,
At this time, I make a humanoid robot. This one: http://letsmakerobots.com/node/27414 and now it's time to use battery power.

Update:

Well, now that I have time for this robot I've discovered that the SSC32 supports at maximum 9 volts and my PSU is 12 volts. The website for robotshop says 6v to 12 volts but the documentation says 7.2v. Help me please

Cheers

Hi, I'm working on a robotic arm, but I don't know what power source purchase. My servos are the problem:

  Currently I am having problems with object tracking.  My current set up is a Dagu compound eye on a Dagu pan/tilt braket with 2 micro servos in it for turning.  All of that is hooked up to a picaxe 28x1 board correctly, but I run into my problem with my code.  My code kinda worked but was really jerky and will still move when there is nothing there.  Also sometimes it will go like it has a mind of its own.  I thought it was moving when there was nothing there because I made it read the two eyes on opposite sides and jus

I was working on my first robot and it looks like my servo just died.  One works and one doesn't when I swap the two, the "dead" one doesnt work with the "good" hookup.  Are servos that delicate?  Its a GWS continuous rotation servo.  Was working fine, then ran for a while with a wierd ground, then nothing.

 

Thanks for any suggestions.

Edit    Sorry, should have read this first.

Not sure I'll be able to implement fritsl's solution, though.

 

I have a humanoid robot, which has 16 original servos, plus I have added 2 standard servos in claws, and recently 2 more micro servos for the head.

These 2 micro servos occasionally get a bad case of the "jitters", not all the time, but intermittently.

ok. Im trying to build a minature arm to lift and move small things. Ive got it built with 4 servos connected to a picaxe 28X project board but i really have no idea as to how i am going to control it. Ive bought a couple of playstation analog sticks which i want to use to control the robot but i do not know how to connect or encode them.

So can anyone make a suggestion as to how i would go about this. thanks

Hey guys I have a arduino motor shield from adafruit and I want a code for it so that i can control two motors from it. So please could you post a code for it. Also could you tell me that can I connect 2 servos and 2 motors on the shield at one time without having any problem.

Thanks for your help.

Allthough these chips are actually called LED drivers they are apparently capable of controlling servos...up to 16 of them :) There is even an Arduino library available for doing so. Pretty cool stuff. But I was wondering if anyone has any experiences with this? If yes then I'd like to know more about it. If not well then consider this a tip to keep in mind the next time you run out of servo pins ;)

I was just wondering..does anyone have experiences with the 8g microservos from DAGU? I'm talking about item 19 in the PDF found on this page. How do they perform compared to other generic servos of similar size like HXT900 or TowerPro SG90?

in my robot SC-QR-1 i have allready used all 8 servo-ports.

but can i still ad a laser(to see where it looks), a speaker(for it to call hor help or showing some sound-emotions..   etc.) and some leds(like a red to show power, white/bright to help my "primary-back-mounted-not-night-vision-spy-camera") 

and if yes would the servos disturb the lasers, speaker and leds?

and i was also thinking, stuff like the sharp ir sensors have ir leds in them, could i attach an led or laser to those pins??

 

please reply!! :D

I want to hook up 3 servos to some batteries.  Since it show it operate at 4.8v and 6v, that mean I need 6v to get the most out of one.  Does that also mean I just need 6v for altogether to make them all move.  They will all be moving at the same time.  I figure I would need more V then that but maybe it would have to do with mah.  Could someone explain how it able to all three use the same power source.  Also does having more mah mean the battery last longer or make it stronger??? thanks in advance.

Hello LMRers,

I've never used Servo's nor microcontrollers in any of my robot projects, always computers, dc continuous or steppers motors, and solenoids!

So, last Christmas Santa gave me an Arduino Duemilanove (I love Santa).

Now, I'd like to get some steppers.

I was wondering general advice, shops, prices, and other considerations of my nerdy bretherin 

This seemed like pretty good prices .. http://www.hobbypartz.com/servos.html  

I don't know if you guys already knew about these 2 very useful library to drive servo motors from the arduino, basicly you don't need to use analog write with an hexadecimal value to drvie the servo by PWM, you just write in degrees the angle and direction you wish the servo to go and it goes! 

Anyway here it is :

I was wondering whether RC toys are a good source for components. I came across a RC plane with two motors and two servos that only costs €25. This seems like a very good deal to me, or would this be a bad idea?

What are your experiences with demolishing toys for the greater good, or do you have an alternative cheap source of components?

Here ( http://letsmakerobots.com/node/80 ) Frits had mentioned that either Arduino or PICAXE can control such and such number of servos. I'm pretty new to microcontroller world, so maybe my question will sounds a bit stupid... but I don't really get what we mean by saying "can only control X servos"? Does it actually mean, "platform X can have up to N serial outputs"? Because, AFAIK that's what servos are, aren't they?

Now, I can understand that PICAXE has also limitations due to the built-in Basic interpreter; but why Arduino?
