Robotic shorts have been developed by researchers at the Technical University of Munich (TUM) to assist limited mobility in older adults and individuals with physical disabilities. These smart robotic shorts are designed to make walking and jogging easier for users, with an 18% reduction in energy consumption compared to unaided walking. The system adapts to the speed at which a person is moving, providing individualized support without the need for pre-settings.
The WalkON system, a pair of soft robotic shorts, is designed to enhance walking efficiency by assisting hip flexion. The compact and lightweight design uses a controller based on natural leg movements to autonomously assist leg propagation. In a study published in Nature Machine Intelligence, researchers found that participants experienced a significant reduction in metabolic cost while using WalkON during walking activities. Young adults walking uphill saw a reduction of 18% in energy consumption, while older adults walking on level ground experienced a 10.48% decrease.
The system is user-friendly and does not require extensive setup, allowing users to put on the robotic shorts and start using them within minutes. The technology has the potential to improve overall mobility and independence for users, leading to a positive impact on their quality of life. Professor Lorenzio Masia emphasized the benefits of walking for improving metabolism and overall well-being, particularly in the later stages of life.
When a user transitions from standing to walking, artificial tendons in the WalkON system extend from the thigh to a waist belt, providing support to the hip flexors and reducing the load on them. A measuring device attached to the tendons determines the hip angle and velocity, sending signals to the motors for precise assistance during the walking process. This innovative technology aims to promote physical well-being and advance mobility for individuals with limited mobility.
Overall, the development of robotic shorts like WalkON shows promising implications for improving efficiency in outdoor walking and enhancing overall physical well-being. By providing individualized support and reducing energy consumption, these smart robotic shorts have the potential to transform the way older adults and individuals with physical disabilities engage in physical activities. As technology continues to advance, wearable assistive devices like WalkON are expected to play a significant role in promoting mobility and independence for users of all ages.
