Few common failure cases in mobile robots
This work addresses failure reduction for mobile robots in hazardous environments, but it is incremental as it offers general advice without new methods or data.
The paper identifies common failure cases in mobile robots used for remote inspection, surveying, or rescue missions, based on real experiences, and provides generic suggestions to reduce these failures, though no concrete numbers are reported.
A mobile robot deployed for remote inspection, surveying or rescue missions can fail due to various possibilities and can be hardware or software related. These failure scenarios necessitate manual recovery (self-rescue) of the robot from the environment. It would bring unforeseen challenges to recover the mobile robot if the environment where it was deployed had hazardous or harmful conditions (e.g. ionizing radiations). While it is not fully possible to predict all the failures in the robot, failures can be reduced by employing certain design/usage considerations. Few example failure cases based on real experiences are presented in this short article along with generic suggestions on overcoming the illustrated failure situations.
