Position Input/Output robot arms with Arduino UNO

Hey everyone!

This will be my first project using an Arduino, and I admit it is a little ambitious;

I plan to use an input robot arm made up of rotary potentiometers, to control another output arm made up of servo-motors. The end of the output robotic arm will be an electromagnet, operated by a simple pushbutton on the input arm. I plan to also have a 'store position' button on the input arm, to store the current position of the POTs, which can be saved and looped at a later time to allow the output arm to serve many different purposes.

To provide easier understanding, here is a video link of a great project which inspired me to try this myself:

I plan to use an Adafruit Servo-shield I2C for my PWM outputs, instead of using up outputs on the Arduino, and saving them for feedback from the potentiometers.

I would love to hear any positive or negative feedback and thoughts on this project!

It would be great to see if anyone has any experience in such a project, advice, obstacles, or tips and tricks to accomplish this task in the simplest way possible.

Thanks

Ok, that is just unwatchable. Would have been better if a schematic had just been posted.

Why don't you figure out how to control one of these with an Arduino to start, then add electromagnet, then add pots for the arduino to read to translate into position, then add another robot arm to control the pots.

Hack the controls on the remote box to start.

What an awful video! I'm still dizzy.
