Polite ActivityBot Variation

Don’t like cats? Or perhaps you just want to try out some different sounds?

The Polite ActivityBot is a variation of the same code base, with different WAV files for the three behaviors. Instead of meowing, purring, and hissing, Polite ActivityBot uses its words to nicely request that you move out of its way.

So Polite!

The behavior code itself is exactly the same, so if you want an explanation of how Polite ActivityBot works just look back one page to “How KittyBot Works”. The code download above already has the new WAV file names in it, you just need to upload the included WAV files to your sd Card. To check out Polite ActivityBot in action, watch the short video below.

  Polite ActivityBot.c

  Version 1.0, 10/31/2013

  https://learn.parallax.com/activitybot

  Requires abdrive version 0.5.5 and wavplayer 0.9 or above

  Drive forward until object detected with PING))) sensor on P8, within 20 cm.
  Stop and play 1st audio response from SD, then recheck for object. If it moved,
  play 2nd audio response and continue. If it did not move, play 3rd audio response,
  rotate left or right at random until clear path is detected, then drive forward.
