Hello my friend!
Here I'll show you how I made a Robotic Arm controlled by Intel Edison and commanded by Leap Motion.
The 3D model used in this project is a very good open source project found here: http://inmoov.fr
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Building the Arm
First of all, you need to print the parts of a right or left hand. I choose a right hand.
The tutorial to build the atm can be found here:
Step 2: Nylon Strings
I'm using nylon strings with 0.4'm of diameter.
To fix the strings on end of fingers I used a connector like the picture attached. This connector I found in a electric bar connectors and cut each one in a half.
Step 3: Fixing Nylon Strings on Servo Motors Wheel
To fix the nylon on servo motor wheel I developed a special pin. Turning this pin you can found the exactly strings position needed.
Step 4: Programming the Intel Edison
To program the Intel Edison you need to merge two Arduino sketches: the servo control and the simple wifi web server.
The simple wifi web server will receive the commands to control the servo motors.
Important: Intel Edison have just four PWM port. You will need to put two servos in the same board pin.
Attached here you can find the my source code.
Step 5: Leap Motion Controller
Install the Leap Motion in your computer and test it.
You can use your favorite leap motion SDK to send to Intel Edison the specifics commands.
Or, just open a web browser in your computer and enter the url from your Intel Edison with the port 8080. Something like this: http://192.168.0.10:8080
To control de Robotic Arm from other device, just call this address http://192.168.0.10:8080/[180,180,180,180]. The number "180" represent each controlled finger and it can be between 0 and 180.
