How to "size" a servo motor? Answered

I have a 28lb solar panel that I'd like to position with servo motors, but not having worked with Servos I'm having a tough time trying to understand how to size the servos that I'll need. I'm finding a ton of "hobby"/"toy" servos that are rated at 25/30KG but am I under/over-thinking that would equate to the ability of those servos handle the full weight, if centrally positioned, of a 28lb array? I get that if they weren't centrally positioned I'd need to figure in leverage weight multiplication, etc., but if they were positioned in the center of the array to form 2 axises would a 30KG servo be able to handle the weight of the array?

How can you increase the range of a servo without losing the positioning feedback system?

I am trying to use them for the joints of a robotic arm. I have the Towerpro mg996r servo. Also the servo won't attain full ranged that can be reached when turning it by hand. By hand I can turn it about 240 degrees but through a micro-controller (arduino mega 2560) it only turns about 180 degrees. If it can get the range that I can get by hand that would also be enough. I might be using the incorrect code or something, not sure exactly what the problem is. I would greatly appreciate any help or ideas.

Controlling two servos with one pin and a NOT-gate

Here's an interesting idea. It may be possible to control two servos independently with only one output pin and an inverter/NOT-gate. Normally, a servo is at its 'center' position when a pulse is 1.5 ms & its angle (or speed for continuous servos) is based on the difference between the length of time of the pulse it received & the base-time of 1.5ms. The servo itself does not react to the time BETWEEN pulses however. If the signal was inverted, the result would be a pulse with a time being that of the time between pulses of the initial signal. If the width of a pulse and the time between pulses can be independently controlled, then it would be possible to control one servo with the signal directly, and another servo using the inverted signal. I found something similar here [http://www.diyrc.com/reversers.htm] but it seems to be intended for 'reversing' the signal used to control one of the servos.

Transform a Servo into stepper?

Hi, I'm wondering if it is possible to transform, with mecanisms like in watchmaking, a sigle servo into a stepper. When the servo turns left, a crank will turn of a fixed amount of degree in the clockwise direction. When the servo turns right, a crank will turn of a fixed amount of degree in the anti-clockwise direction. The main advantage of this is that we can have a stepper motor created with a servo. I'm searching such projects without results... Am I the first one to think about this ? How can I imagine such a mecanical project ? Thank you

How to fix a servo with a burned out green circuit board?

I have a Hitec HS -805BB servo that seems to have a burned out component on the green pcb circuit board (the component looks like a H- bridge of some sort). For this reason the servo won't work. I tested the potentiometer, gears, and DC motor inside this servo and they work great. I was wondering if I could somehow get this servo working again since it was really expensive. Could I cut out the current burned out green circuit board and wire the other working components through an arduino? So pretty much use an arduino as a replacement circuit board for the servo. If this is possible how would I wire it and what would the code look like.

Is there a way to calculate how much weight a servo can lift? Answered

It says they are rated 3.9kg - cm so for 1 cm pole, its 3.9kg, and how can I convert that to see how much weight it can hold? the servo's that move the legs I'm not worried about but the ones that lift the chassis, make me have second thoughts.. The chassis is less than 1 pound, so at the point of the servo is about an inch and a half away, will it be able to lift.. Also, 6 servos will be lifting, so does this add all the torque together for a total product?

Servo Help!

First of all, I'm not the best with Technology projects, just putting it out there in case its an obvious answer. Anyway, I have an arduino project that im working on. All it is is a servo that spins after 24 hours, I thought it would be a simple project (I've worked with arduino a little bit) and I wired it up correctly, I'm sure of that, but after I coded the program, the servo wouldn't spin! It just made a dull buzzing sound. At first  I thought it was my program, so i tried just about every basic "sweep" program i could find online about servos. Every program had the same result, a faint buzzing sound and no spinning. Next i thought, maybe the 5v wasn't enough to power the microservo, so i used a external 9v and ended with the same result, buzzing, no movement. Can Anyone Help me?! Please! Is it just a simple solution? Or is my arduino micro controller not working! Please help me because i would like to enter the project in a contest that ends soon! Thank You!
