Abstract
Construction workers often rely on stilts to perform tasks at elevated heights, such as drywall installation and ceiling work. However, traditional stilts offer no active support, requiring significant skill and balance, which can lead to falls and workplace injuries. To address these challenges, this research focuses on developing an advanced haptic force feedback system for stilts, aimed at creating a safer working environment on construction sites. The system integrates two linear actuators per leg and a Raspberry Pi 5 with 9-axis inertial measurement units (IMUs) to provide real-time balance and feedback control. By enhancing stability during movement, this technology offers workers an intuitive self-balancing mechanism. The haptic feedback system is designed to improve the learning curve for stilt users by offering precise force adjustments, thereby reducing strain and improving overall usability in dynamic construction settings. Key components of this system include the Raspberry Pi 5 for processing, IMUs for motion sensing, and various electrical components that enable real-time adjustments. These innovations in stilt design represent a significant advancement in personal protective equipment, with the potential to transform construction safety standards by making stilts more accessible, functional, and user-friendly. This work lays the groundwork for future advancements in wearable robotic assistance, aimed at reducing workplace injuries and enhancing productivity.
