Controlling others body by using your body sounds cool! So I decided to build something that allows people to control their friend's arm.
inspiration: I got inspired by this idea after I watched TED talk about controlling others body using brain waves! check it here: https://bit.ly/1dw6sdf
I thought that I can make something similar using variable resistor.
HOW it works?
It is consists of two suits, one for the master (the person who will give order) and the other for the slave (the person who will be controlled).
Salve Suit: Contains 2 high torque 9k servo motors to pull the arm depending on the signal it receives from the master suit.
Master suit: Contains one variable resistor that changes when close or open your arm.
watch this two videos to understand how it works:
what heppens when the variable resistor changes: https://bit.ly/2lvtWIL
final project: https://bit.ly/2lVITEg
The Arduino code:
I chose arduino nano to do this project, feel free to use any other type.
I used the knob library the already exists in arduino example folder. Click File>Exampels>Servo>knob
you will need to add one more servo variable inside the code and duplicate the code.
Connection:
You can find simple connection with project photos. Add more servo and connect it to any digital or analog pin you want and the same for the variable resistor.
I made the connections on a PCB to make sure that it doesn't move.
Design:
To connect parts to each other I used 6mm stainless steel shafts, lengths depending on how long your arm is. epoxy glue to hold the shafts in holes and the variable resistor in place.
Screws: M3.5 and its nuts.
Stainless Steel: 6mm diameter. 30cm and 15cm tall.
infill: 30% for all parts, 100% for joints and movement order file.
supports: only for slave arm ring.
