Fun with Rovio
Note that RoboRealm runs on your PC and communicates to the Rovio over the 802.11 wireless protocol. This means that you
will see what the Rovio sees on your PC screen.
What can you do once RoboRealm is installed with the Rovio Robot? Here's a couple possibilities that you can load and run in RoboRealm:
One of the issues that plagues the Rovio (as also remedied via hardware in this Hackaday article) is the high lighting requirements needed in order to see anything through the camera. During
the daytime the image works well, but towards the evening or in artificially lighted rooms the camera image
produced is of very low contrast and lighting. Simply using the Rovio module with the "Enhance" checkbox selected
improves the image quite a bit!
Keyboard Driving Want
to just drive your Rovio around using your PC keyboard? Try this robofile out to understand how to trigger movements
based on keypresses in RoboRealm.
Joystick Driving If
the keyboard is not your desired interface try the joystick control instead. The joystick is superior to the keyboard
driver as it can specify different speeds based on the tilt/pan of the joystick. This allows finer control over your
Rovio than just using keypresses.
Chasing Light A natural
behavior of most animals is to avoid or target light. For example, after a pigeon accidentally flew into our building it kept trying to
fly up towards the ceiling and bumping into the overhead fluorescent lights. It would determine that the way was blocked
and would try the next light in an effort to fly towards the light (assumed sunlight) and escape the confines of the building.
The Rovio has a built in Radar or otherwise known as an IR (Infrared) Distance sensor that will trigger when an object
gets close to the front of the robot. Using this simple sensor you can implement a nice obstacle avoidance
routine that steers the Rovio away from harm.
Laser Steering A fun
way to steer the Rovio using a laser pointer. Point the laser within view of the Rovio's camera and it will attempt
to move towards the laser.
Chasing Movement Detecting
movement is also a useful behavior for a robot to have. The issue with mobile robots is how to remove the movement
caused by the robot versus what it moving independently.
Finding a Bullseye Target
Thinking about an indicator for a homebase for the Rovio? A bullseye has some nice properties that can easily be
exploited to extract it out from a scene even when moving.
