Overview

Experimental study explores collaboration perception with robots in construction, indicating cognitive workload reduction.

Key Points

  • To investigate how collaboration levels with mobile ground robots affect perceptions of workload and safety in construction tasks.
  • Between-subject experimental study conducted during real-world tasks like material handling and bricklaying
  • Examined three levels of collaboration: coexistence, cooperation, and collaboration
  • Participants evaluated cognitive workload, safety perception, and attitudes toward robots.
  • Collaborating with mobile ground robots significantly reduced perceived physical workload compared to cooperating or coexisting (exact metrics not provided)
  • No significant differences in cognitive workload factors like mental demand, safety perception, or attitudes towards robots across collaboration levels
  • Findings indicate mixed effects on cognitive workload and safety perception.
