What challenge concerning weather conditions might affect robots outdoors?

Rain can significantly impact the performance and visibility of robots operating outdoors. When robots are exposed to wet conditions, their sensors may struggle to function accurately due to water interference, which can lead to misreading the environment. Additionally, rain can obscure cameras and other visibility aids, making it more challenging for robots to navigate and perform tasks effectively. Wet surfaces can also create traction issues, potentially causing robots to slip or become immobilized. Thus, rain directly affects both the operational efficiency and safety of outdoor robotics systems.

While excessive heat can indeed lead to malfunctions, particularly in sensitive electronic components, rain presents a more immediate and noticeable challenge in outdoor environments, influencing several operational aspects at once.
