Carnegie Mellon Builds Wearable Robotic Arm to Assist Workers
Carnegie Mellon researchers create a modular robotic arm that attaches to a backpack to give users an extra limb for complex assembly tasks.
Researchers at Carnegie Mellon’s Biorobotics Lab repurpose their modular snake robot technology to create a wearable robotic arm. The system attaches to a backpack-style frame and acts as an extra limb rather than a traditional exoskeleton. This self-directed student project shows how mixing and matching existing robotic modules leads to entirely new research directions.
The wearable arm targets industrial tasks that typically require two people to complete, such as holding a heavy part against a ceiling while another worker fastens it. By wearing the robotic limb, a single worker holds the piece in place overhead using a game pad or voice commands. This setup drastically reduces the need for extra manpower in automotive and airplane assembly lines.
Currently, the system supports just one extra limb due to the challenges of user control, though the hardware physically allows for multiple arms like a comic book villain. The creator admits that managing additional limbs quickly overwhelms the user's ability to operate buttons or voice commands. The team continues to explore how to make this extra helping hand more intuitive for everyday workers.
