Area of Science:

  • Robotics
  • Biomechanics
  • Assistive Technology

Background:

  • Tripping is a prevalent issue, particularly affecting individuals with joint weakness and the elderly.
  • Existing solutions often rely on complex sensing systems like cameras or map reconstruction.
  • There is a need for intuitive and effective assistive devices to mitigate tripping hazards.

Purpose of the Study:

  • To develop and evaluate a lower limb exoskeleton system designed to prevent tripping.
  • To enable individuals with joint weakness to navigate obstacles and stairs safely.
  • To create a system that does not require advanced environmental perception for obstacle avoidance.

Main Methods:

  • Implementation of a lower limb exoskeleton controlled by an impedance controller.
  • Utilization of a virtual potential field to regulate the user's motion and avoid obstacles.
  • Testing through simulations and physical experiments to validate the system's effectiveness.

Main Results:

  • The exoskeleton successfully assisted users in avoiding trips when encountering obstacles.
  • The impedance controller effectively synchronized with the pilot's movements.
  • The virtual potential field method proved effective in obstacle negotiation without external sensors.

Conclusions:

  • The developed lower limb exoskeleton offers a promising solution for preventing trips in individuals with joint weakness.
  • The sensor-free approach simplifies the system and enhances its applicability.
  • This technology has the potential to improve mobility and reduce fall-related injuries in vulnerable populations.
