We designed a robotic hand that communicates in American Sign Language, alongside a wearable glove controller that operates it wirelessly. The glove integrates a microcontroller to process information, sensors to capture hand positions, and a battery to power all functions. The robotic hand incorporates multiple motors to control each finger individually and receives commands from the glove through Bluetooth connection. We implemented a vibration feedback system in the glove that notified users when the robotic hand interacted with objects.
The project successfully creates a wireless wearable device capable of controlling a robotic hand. The system signs various ASL numbers and letters at an appropriate speed and with accuracy comparable to the user’s signing. The glove is simple enough for anyone to use and effectively capture users’ hand movements.
