EMG Exploration

New recruit, software and machine learning specialist, Jerry Xu shows off his first project in the group. EMG-controlled Flappy Bird.

Niko is a differential signal between each MyoWare (two on each arm) to give him 4-directional control, forward, backward, left, and right, using just his arms . This system works by putting the output of the MyoWares against each other. Whichever has the highest output triggers the action.

Up to this point, all EMG projects have been limited to single-channel control per muscle group. Eventually, we want to be able to execute dozens of learned and natural functions on each arm. This is the first working example of this idea.

A Neopixel strip is used to show visually the level of muscle activation as picked up by a single MyoWare. This is a great example and foundation for using gradients for different tasks.

Niko and Colin collaborate to control an RC car in 4 directions. Colin controls forward and backward while Niko steers.

First test using custom conductive fabric electrodes was a success! The signals were weak but consistently present. Using an amplifier, such as the ADS1299 from TI, will boost the signal. These electrodes can then be woven into clothing which will make them reusable and serviceable by the end user.
