You could add a onrelay that fires the same bricks relay again, which'd result in any other onrelay events being constantly repeated
It'd look like this (should be right, on mobile atm though so i can't confirm this atm)
OnBotSpawn > Self > fireRelay
OnRelay > Bot > PlayGesture (gesture to play)
(Some delay time) OnRelay > Bot > PlayGesture > root
(Delay time here after previous time to loop again) OnRelay > Self > fireRelay
