Mate Arm Controller

Controlling others body by using your own sounds cool, so I decided to build something that lets people control their friend's arm. I got inspired after watching a TED talk about controlling others body using brain waves. Check it out here: https://bit.ly/1dw6sdf. I thought I could make something similar using a variable resistor. Here's how it works: It consists of two suits, one for the master (the person giving orders) and the other for the slave (the person being controlled). Slave Suit: This contains 2 high torque 9k servo motors to pull the arm depending on the signal received from the master suit. Master Suit: This contains one variable resistor that changes when you close or open your arm. Watch these two videos to understand how it works: What happens when the variable resistor changes: https://bit.ly/2lvtWIL Final Project: https://bit.ly/2lVITEg The Arduino Code: I chose an Arduino nano for this project. Feel free to use any other type. I used the knob library that already exists in the Arduino example folder. Click File>Examples>Servo>Knob. You'll need to add one more servo variable inside the code and duplicate it. Connection: You can find simple connections with project photos. Add more servos and connect them to any digital or analog pin you want, as well as the variable resistor. I made the connections on a PCB to keep everything in place. Design: To connect parts together, I used 6mm stainless steel shafts, lengths depending on how long your arm is. I used 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 tall and 15cm wide.
