A Real-time Motion Tracking Wireless System for Upper Limb Exosuit Based on Inertial Measurement Units and Flex Sensors (TECHNICAL NOTE)
Authors
Abstract:
This paper puts forward a real-time angular tracking (motion capture) system for a low cost upper limb exosuit based on sensor fusion; which is integrated by an elastic sleeve-mitten, two inertial measurement units (IMU), two flex sensors and a wireless communication system. The device can accurately detect the angular position of the shoulder (flexion-extension, abduction-adduction and internal-external rotation), elbow (flexion-extension and forearm supination-pronation), and wrist (flexion-extension) joints. In addition, the state of the hand (opened-closed). Finaly a PID controller is applied to the exosuit in order to replicate the movements performed by the arm into a 6 DOF robot arm.

Survey of Motion Tracking Methods Based on Inertial Sensors: A Focus on Upper Limb Human Motion
Motion tracking based on commercial inertial measurements units (IMUs) has been widely studied in the latter years as it is a cost-effective enabling technology for those applications in which motion tracking based on optical technologies is unsuitable. This measurement method has a high impact in human performance assessment and human-robot interaction. IMU motion tracking systems are indeed s...

Real-time limb motion tracking offers a natural and intuitive way to interact with virtual environment in VR head-mounted displays. In this report, we present an affordable while accurate and lowlatency tracker design using a single IMU plus a flex sensor. A kinematically-constrained model is developed to fuse the 7-degree measurement and reconstruct the state of upper limb. We build a prototyp...

A telemetry system for real-time monitoring of the motions, position, speed and course of a ship at sea is presented in this work. The system, conceived as a subsystem of a radar cross-section measurement unit, could also be used in other applications as ships dynamics characterization, on-board cranes, antenna stabilizers, etc. This system was designed to be stand-alone, reliable, easy to depl...
full textUse of multiple wearable inertial sensors in upper limb motion tracking.
This paper presents a new human motion tracking system using two wearable inertial sensors that are placed near the wrist and elbow joints of the upper limb. Each inertial sensor consists of a tri-axial accelerometer, a tri-axial gyroscope and a tri-axial magnetometer. The turning rates of the gyroscope were utilised for localising the wrist and elbow joints on the assumption that the two upper...

Here an inertial sensor-based monitoring system for measuring and analyzing upper limb movements is presented. The final goal is the integration of this motion-tracking device within a portable rehabilitation system for brain injury patients. A set of four inertial sensors mounted on a special garment worn by the patient provides the quaternions representing the patient upper limb's orientation...
