Hello Guys!
I am a newbie around here and in the world of micro servos and controllers and robotics in general. I have a small project in mind and I wanted to incorporate servo motors on my project if it's possible enough. I have attached a .pdf file of what I was planning to do. Basically, I need servo motors and a controller to control multiple motors to open and close the panels individually. And I was thinking if using a 3-way rocker switch to open and close the panels is possible? I am doing some research about servo motors since this is the first time that I am interested in using them, I was looking for a micro servo motor that can hold a load of at least 1.5 kgs., when I was doing some research, on the specifications of the motors, there's this mention of kg.-cm./oz.-in. on the motors. I am not quite sure what those stands for.
Sorry about this newbie question! Any help would be much appreciated!
Which controller and servo motors will fit my small project?

Here's another screenshot of it. I didn't realized I can't upload .pdf files. :P

The kg.-cm./oz.-in specifications are a measure of torque. If a servo is rated for 1kg/cm, that means it can exert a force of 1kg at the end of a 1 cm arm attached to the shaft. The basic laws of mechanics apply. If you double the length of the arm, the available force is cut in half.I was looking for a micro servo motor that can hold a load of at least 1.5 kgs., when I was doing some research, on the specifications of the motors, there's this mention of kg.-cm./oz.-in. on the motors.

Thanks Bill!
Oooh. I see. Now it makes sense.

any suggestions for a good controller and servo motors? And is using rocker switch to control the servos possible?

A microcontroller like an Arduino can drive several servos easily. For a small form-factor, there are plenty of Arduino compatible choices such as the Pro Trinket or Metro Mini.
You can hook up the rocker switch to one pair of digital pins for control. Each servo will also require one digital pin.
