  Design and Performance Evaluation of PLA-based Umbrella Wheels for Stair-Climbing Robotic Applications

  By Penta Srinivas, G.Yedukondalu, Bondili Harshith Singh

  Abstract: Staircase climbing robots require a complex design capable of navigating various stair configurations. A crucial component of such robots is the wheel mechanism. This paper focuses on the umbrella wheel mechanism and its application in staircase climbing robots. In this study, a PLA–based umbrella wheel structure is developed and fabricated using fused deposition modeling (FDM) for application in stair-climbing robots. The umbrella wheel geometry enables transformation from a circular rolling …
