That is really cool. How did you make it? I’m pretty sure that part doesn’t come in the FLL kits or does it now?
Either way, that is a very slick drivetrain for an FLL bot.
I forgotten to mention that the wheel was purchased by our trainer and could be found online at here:
oh and i forgotten to mention that we are from singapore and so we dun know how is FLL played, can give us some info??
FIRST LEGO League (FLL) is a competition for middle school students (6th-8th grade or so) to build LEGO robots to complete a challenge. Teams of 10 or fewer students build a robot to complete the challenges, while simultaneously researching topics related to the theme for the year and making a presentation on one particular topic. FLL is international; I seem to remember there being teams in Singapore, but I don’t know where. Also note that the theme (and therefore the game the robots play) changes every year.
See http://usfirst.org/roboticsprograms/fll/default.aspx?id=970 for further information, including how to join in the fun.
By the way, should you decide to get into FLL, I’m 90% sure that those wheels would not be legal on a competition robot; however, presentations have few, if any, restrictions on robots used as props.
