NIBObee auf Linie

[Christian Strasser]

Hallo Zusammen,
habe zu Weihnachten meinen ersten Roboter geschenkt bekommen. Habe jetzt den NIBObee mit meinem ersten wirklich selbstgemachten Programm beschrieben. Hier geht es um das verfolgen einer schwarzen Linie. Es klappt schon ganz gut. :p

Gruß
Christian

Hi,
I appreciate your work.But can you send the picture and more information about your robot.
Thanks in advance.

Hello judith222,

my robot is a construction kit NIBObee from nicai-systems. NIBObee is an autonomous robot particularly developed for pupils and students. It can be programmed in C, C++, Java and assembler. It's my first one! At the video, you see my first self made programm at C. For more information see at http://www.nicai-systems.com/en/nibobee.html.
