1. A computer-implemented method for providing contextual instruction to a robotic apparatus, the method being performed by one or more processors configured to execute computer program modules, the method comprising: transmitting a signal using a carrier of first variety, the signal being configured to irradiate an object; and transmitting an indication using a carrier of second variety to the robotic apparatus, the second variety being distinct from the first variety, the indication conveying whether detection of the first variety carrier is to be performed; wherein: the signal and the indication provide the contextual instruction, the contextual instruction being configured to cause the robotic apparatus to commence a task associated with a context; the carrier of the first variety includes one or both of (i) a visible spectrum carrier having a bandwidth associated therewith or (ii) a radio spectrum carrier having a multiple access sub-channel associated therewith; the bandwidth is different from another bandwidth associated with another signal comprising the carrier of the first variety; the another signal and another indication provide another context capable of causing another robotic apparatus to perform another task associated with the another context; and the indication is capable of being provided to the another robotic apparatus.
