Wing Project

by akirose_volk on Mon Jun 29, 2020 6:10 pm


I'm currently working on a project where I want to make giant mechanical wings. My plan is to use an Arduino UNO with two servo motors and 2 linear actuators. Can I connect all 4 components so the Arduino UNO?

Each wing weighs approximately 5-7 pounds.

I need the wing function to move like so
-The Servo motors rotate out 90 degrees
-The linear actuators then compress
-The servo motors rotate 90 degrees again and return to the original position
-The linear actuators then extend

I'm not so worried about the coding right now as much as making sure that this is possible and what products are needed. What type or servo to buy, is the Arduino UNO the best choice, will I need other products to supplement the Arduino UNO, and etc.

I'm a complete beginner and having trouble figuring out which parts will work best for the project.

What you want to do is most likely possible. But you will need some rather powerful servos.

Servos will have a torque rating - usually in ounce-inches or kilogram-centimeters. For example, the most powerful servo we carry is rated for 8.5 kg-cm / 120 oz-in at 4.8v.

120 oz-inches, means that it can create a force of 120 ounces at the end of an arm that is 1 inch long. If you increase the arm to 10 inches, the force drops proportionally to 12 ounces. If you have a 40" wing, the force you could generate at the wing-tip would be just 3 oz.

There are higher torque servos available from other sources. But to start with, you will need to come up with a realistic estimate for the torque required to operate your wings. Not just the force required to open and close them - but also sufficient to maintain position while moving around with the wings extended.
