Machines: Problem Solving II

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

    Area of Science:

    • Robotics
    • Biomechanics
    • Rehabilitation Engineering

    Background:

    • Upper limb assistive and rehabilitation robots are crucial for patients with movement disorders.
    • End-effector type robots, like the ARAE, require effective gravity compensation for human upper limbs.
    • Accurate gravity compensation is vital for the practical deployment of these robots.

    Purpose of the Study:

    • To present an adaptive gravity compensation framework for the Assistive Robotic Arm Extender (ARAE).
    • To enable gravity compensation based on real-time estimation of human upper limb posture in 3D space.
    • To enhance the usability and feasibility of 3D end-effector rehabilitation and assistive robots.

    Main Methods:

    • Real-time estimation of human arm joint angles using only robot kinematic data and a human model, without wearable sensors (e.g., IMU).
    • Validation of joint angle estimation accuracy using a motion capture system.
    • Inputting estimated joint angles into a rigid link model to determine the robot's support force profile.

    Main Results:

    • Accurate estimation of human arm joint angles was achieved without external sensors.
    • The developed ARAE robot demonstrated an adaptive support force that adjusts to different human arm postures in 3D space.
    • The adaptive gravity compensation framework was validated for its effectiveness.

    Conclusions:

    • The proposed adaptive gravity compensation framework significantly improves the functionality of the ARAE robot.
    • This sensor-less approach enhances the practicality and deployment of 3D end-effector assistive and rehabilitation robots.
    • The study validates the potential of adaptive gravity compensation for upper limb robotic assistance.
