I’ve seen certain toy robots that have a leash function. Basically, a wireless device that the bot can be trained to follow. Ones I’ve played with in the past use IR technology. It would be nice if a similar function was available to the bot through the user’s smartphone since most people will have it with them anyways. Thanks.
