Cozmo Chat Commands

In addition to the standard chat commands, Cozmo has several specific chat commands available to the owner. You can type these into the chat box on the robot page.

  • .anim NAME this will play the NAME animation.
  • .forward_speed ### this will allow you to adjust how fast Cozmo moves forward / backwards.
  • .turn_speed ### this will adjust how far Cozmo turns left and right.
  • .vol ### This turns Cozmos volume up or down [0...100].
  • `.charge X' If Cozmo is on the dock, force the changin g state. If Cozmo is off the dock, mark the charging state to start as soon as Cozmo docks [on|off].
  • .stay X Set Cozmo to stay locked in the dock, regardless of charge state [on|off].
  • .annotate Enable / Disable the annotated view, to see what Cozmo is seeing.
  • .color or .colour Enable / Disable colour. Colour reduces the resolution of the video.

Note for audio streaming on MacOS:

NOTE : These instructions are out of date. The current method to stream audio involves changing the audio_input_format to avfoundation, video type to ffmpeg and no_camera to true.

The startAudioCaptureLinux function in send_video.py calls ffmpeg with alsa input. If you want to stream audio from your mac use -f avfoundation -i ":0" in place of -f alsa -ar 44100 -ac %d -i hw:%d.

For example:

audioCommandLine = '/usr/local/bin/ffmpeg -f avfoundation -i ":0" -f mpegts -codec:a mp2 -b:a 128k -muxdelay 0.001 http://%s:%s/%s/640/480/' % (audioHost, audioPort, robotSettings.stream_key)
