A Wearable MYO Gesture Armband Controlling Sphero BB-8 Robot

Abstract

In this paper we present the development and preliminary validation of a wearable system which is combined with an algorithm interfacing the MYO gesture armband with a Sphero BB-8 robotic device. The MYO armband is a wearable device which measures real-time EMG signals of the end user’s forearm muscles as the user is executing a set of upper limb gestures. These gestures are interpreted and transmitted to a computing hardware via a Bluetooth Low Energy IEEE 802.15.1 wireless protocol. The algorithm analyzes and sorts the data and sends a set of commands to the Sphero robotic device while performing navigation movements. After designing and integrating the software and hardware architecture, we have validated the system with two sets of trials involving a series of commands performed in multiple iterations. The consequent reactions of the robots, due to these commands, were recorded and the performance of the system was analyzed in a confusion matrix to obtain an average accuracy of the system outcome vs. the expected and desired actions. Results show that our integrated system can satisfactorily interface with the system in an intuitive way with an accuracy rating of 85.7 % and 92.9 % for the two tests, respectively.

Design of a Biomimetic BLDC Driven Robotic Arm for Teleoperation & Biomedical Applications

“…As this robot is primarily conceived as a test bench for experimenting with concepts such as teleoperation, we built a functional ROS package for it that integrates into ROS RViz, Gazebo, and MoveIt for full simulation, kinematics, and motion planning frameworks. Clearly, other types of interactions between the arm and the end-user could be selected, such as, for example, wearable systems and/or BCI [15][16][17][18][19]. The full 3D model is represented, complete with collisiondetection.…”

IoT data analytics architecture for smart healthcare using RFID and WSN

“…The study investigates the entire end-to-end solution for each application and details the technical aspects required. Chu et al present an armband that measures real-time EMG signals of an end user's forearm muscles in a previous study [10]. They validated the system using two sets of trials involving a series of commands performed in several iterations after creating and integrating the software and hardware architecture.…”

“…In addition, BCIs can be beneficial for people with quadriplegia paralysis (severe disabilities). For people with hemialgia or paraplegia paralysis, an MYO gesture armband (Chu et al, 2020) and video-based human action recognition (Sarabu and Santra, 2021) can be suitable to extend their activity.…”
