Abstract: A system for monitoring railcars includes a memory operable to store data associated with monitoring a location of a train. The system also includes a processor communicatively coupled to the memory and operable to receive location signals from a plurality of location devices. Each location device is associated with a respective railcar of a plurality of railcars. The plurality of railcars form the train. The processor is further operable to monitor the location of the train based on received location signals from one or more of the plurality of location devices.

Abstract: Examples and implementations of various robotic mechanisms, devices, components, systems and techniques are provided, including multimodal robotic devices and systems. For example, a multimodal robot can be configured to autonomously reconfigure between two or more primary modes of operation. Such robots may be used in a wide range of applications, including reconnaissance, exploration, search and rescue, military, sports, personal assistance, education, and entertainment and toys. Described examples of multimodal robots can be wheeled robots that use two or more drive wheels to perform various motions and operations.
