Abstract: A method includes creating a publisher configured to send messages over a channel having a shared memory. The method includes creating at least one subscriber configured to receive the messages over the channel by sequentially referencing memory slots of the plurality of memory slots. The method includes determining that the next sequential memory slot is currently referenced by a subscriber. The method includes delaying sending the message by the publisher based on determining that the next sequential memory slot is currently referenced by the subscriber. The method includes receiving an event trigger indicative of message reading by the subscriber. The method includes, responsive to receiving the event trigger, determining that the next sequential memory slot is not currently referenced. The method includes sending the message to the next sequential memory slot based on determining that the next sequential memory slot is not currently referenced.

Abstract: Methods, systems, and devices for managing robot resources are described. A robot receives from an application a request to reserve a particular set of physical resources of the robot. The robot then determines that each of the physical resources in the set are available to the application and, based on the determination, allocates exclusive use of the particular set of resources to the application by (i) generating a token corresponding to the set of resources, (ii) providing the token to the application, and (iii) updating token data that associates the token with the set of resources. The robot then controls access to the particular set of resources such that, while token data indicates that the token is valid, commands from applications that involve the set of resources are only executed when provided with the token corresponding to the allocation of access to the particular set of resources.
