Servo Actuation- Proof of Concept
Apr. 9, 2019—Servo Motor Actuation with a Continuous Force-Based Control System The below video serves as a partial proof of concept demonstrating the effectiveness of our EMG acquisition, pre-processing, processing, and actuation output in accurately controlling and maintaining the posture of a servo.
Logistics Classifier Machine Learning Training
Apr. 3, 2019—Logistics Classifier Machine Learning Training Collect pre-processed training data across subjects with varying gender, musculature, and EMG data Calculate MAV of extensor and flexor using a 200 ms sliding window every 50 ms Calculate the differential between the extensor and flexor MAV for each subject Average all subjects’ MAV values and varying contraction levels Fit...

Progress Report 3 (11/15/18)
Nov. 15, 2018—Previous Goals This past week, one of our goals was to continue our literature review, which was extended to include a patent search, to continue to build a base of knowledge on the relevant subjects and begin brainstorming possible design routes. Another goal was to complete block diagrams to layout the hardware, software, and...
Patent Landscape
Nov. 7, 2018—Patent Landscape- Force Based Controller for Myoelectric Prostheses Novelty of Device: Force-based controller Biomimetic muscle activity to hand posture coupling Dynamic, continuous proportional control Overview: A preliminary patent search yielded a fairly open patent landscape for this device. Among the patents found and considered relevant, the claims used were specific to the mechanical hardware of...
Progress Report 2 (11/06/18)
Nov. 6, 2018—Previous Goals This past week, our goals were to schedule and have a phone call with our main point of contact to figure out shipping details for the prosthesis as well as a weekly check-in time. We also aimed to learn background information about our project both broadly and specifically—the larger scope of our project...
