Abstract: A process for controlling a plurality of mobile-radio equipped robots in a talkgroup includes receiving, at a mobile-radio equipped robot via a wireless communications interface comprising one of an infrastructure wireless communication interface for communicating with an infrastructure radio access network (RAN) and an ad-hoc wireless communication interface for communicating with an ad-hoc network, a group voice call containing a voice-command. The mobile-radio equipped robot determines that it is a target of the group voice call, and responsively text-converts the voice-command into an actionable text-based command. The mobile-radio equipped robot subsequently operates a mechanical drive element in accordance with the actionable text-based command.

Abstract: A push-to-talk (PTT)-enabled communication device with an interface for selecting a talkgroup and initiating a PTT communication with the talkgroup is disclosed. The interface includes a component configured to (1) select the talkgroup in response to the component receiving a first input that causes a rotation of the component, and (2) initiate the PTT communication with the talkgroup in response to the component receiving a second input that is different from the first input. In one example, the interface may comprise a physical PTT button that is rotatable. In another example, the interface may comprise an apparatus with a graphical user interface (GUI) including a PTT-button area that visually rotates.
