Abstract: A unified electronic control unit (ECU) interface provides a bridge from ECU clients to the ECU. The ECU interface may be implemented on a vehicle's onboard computer, and it may be used by clients executing on the onboard computer and, in some cases, by clients outside the onboard computer. The ECU interface may receive a request from a client in a first messaging format, e.g., a local networking protocol used by processes running on the vehicle. The ECU interface translates the request into a second messaging format and transmits the request to the ECU. The ECU interface receives a response from the ECU and translates the response into the first messaging format for delivery to the client. The ECU interface may further perform authentication of the client and/or the ECU, packet serialization of the response from the ECU, packet diagnostics, and other functionalities associated with communicating with the ECU.

Abstract: Methods and systems are provided for facilitating communications between an internal computing system and vehicle electronic control units. In some aspects, methods and systems are provided and can include receiving data from a plurality of vehicle electronic control units, the data from the plurality of vehicle electronic control units being processed by utilizing a control area network protocol, processing the data received from the plurality of vehicle electronic control units by utilizing a robotic operating system protocol, and providing robotic operating system data based on the data processed by utilizing the robotic operating system protocol to an internal computing system.

Abstract: A rollator having a first side frame and a second side frame; the first side frame comprising a first side frame intervening structural portion; the second rolling side frame comprising a second side frame intervening structural portion; a central platform having a first platform side and a second platform side; and first and second track mechanisms respectively coupling the first and second side portions to the first and second platform sides of the central platform; the first and second track mechanisms permitting independent movement of said first and second side frames relative to said central platform.
