Investigating the application, benefits and challenges of an exoskeleton system in the final assembly of automotive production

Abstract

Abstract When it comes to manual assembly tasks, work related injuries due to poor ergonomics is a major concern in today’s automotive industries. To approach this challenge, several automotive industries have started using new technologies such as Exoskeletons to make the assembly task easier. This research study is focused on investigating the application, potential impact and challenges of the exoskeleton technology at the final assembly in the automotive industry. This was made possible by performing subjective and objective data collection of the exoskeleton in a factory and lab setting. Factory tests were performed with a focus on above shoulder work tasks at Volvo Cars and Volvo Trucks in Swedish plants. Lab tests were performed with the same focus at Chalmers University of Technology. The data was captured through interviews, observations and electromyography. Based on the valuable feedback from the participants, the equipment had positive effects on the shoulder and back while working above shoulders but there were negative effects regarding movability and resistance while working at a lower height. Based on lab testing, there was a reduction in muscle effort with the exoskeletons when compared to muscle activity without the exoskeleton. In addition, further recommendation has been made to investigate the technology for a longer time period in order to evaluate long term effects.
