Control NAO with a remote control
When ALInfrared receive a remote control button, it raise an event with every information about it. The event name is InfraRedRemoteKeyReceived.
Every information of the event are also keep in memory.
The event array and the separated data are describe in the following table:
| Event / Data | Type | ALMemory | Description |
|---|---|---|---|
| Event | array | "InfraRedRemoteKeyReceived" | Contain the 5 following data |
| Data | string | "Device/SubDeviceList/IR/LIRC/Remote/LircCode/Sensor/Value/" | LIRC hexa code (LIRC documentation online) |
| Data | int | "Device/SubDeviceList/IR/LIRC/Remote/Repeat/Sensor/Value/" | Same frame of the button receive in one shot |
| Data | string | "Device/SubDeviceList/IR/LIRC/Remote/Key/Sensor/Value/" | Name of the button |
| Data | string | "Device/SubDeviceList/IR/LIRC/Remote/Remote/Sensor/Value/" | Name of the remote (device model) |
| Data | int | "Device/SubDeviceList/IR/LIRC/Remote/IrSide/Sensor/Value/" | 0 means received on the left eye, 7 means on the right eye. |
Python example to receive and display remote buttons event:
from naoqi import * import time # create python module class myModule(ALModule): """python class myModule test auto documentation""" def pythondatachanged(self, strVarName, value, strMessage): """callback when data change""" print "----------------------------------------------------------" print "Data changed on", strVarName, ": ", value, " ", strMessage print "----------------------------------------------------------" broker = ALBroker("pythonBroker","127.0.0.1",9999,"127.0.0.1",9559) # call method try: lirc=ALProxy("ALInfrared") repeatThreshold = 10 eventName = "InfraRedRemoteKeyReceived" lirc.initReception(repeatThreshold) pythonModule = myModule("pythonModule") prox = ALProxy("ALMemory") prox.subscribeToEvent(eventName,"pythonModule", "pythondatachanged") except Exception,e: print "error" print e exit(1) time.sleep(10) exit(0)
