Selfbalancing robot for fun is capable of:
actually, to balance; :)
to ride and turn;
to deviate from obstacles using distance sensors;
all of it are controlled through an access point distributed by the robot itself, which acts, among other things, as a web server, issuing a control page to a standard browser upon request.
