DJEMY 3.0 by UBAYA - Snow Fighter Robot '99

This robot is called "Snow Fighter" as the default name given by the 
organizing committee of ROBOCON 1999 held in Japan on March
2000.
We didn't go to international contest in Japan because we lose in regional 
selection held by POLTEK ELKA ITS, although we know that our fail was not 
my false but the judges'.  Nevermind, we still feel happy because we were 
able to build that robot as well as the rule book requirements.
The size of this robot is 120cm x 120cm x 120 cm with a weight only 35 kg. 
This robot can be ridden by a student and driven using a joy stick. We use 
some relays and electronic control system here. This robot can move back 
and forward, pivot on one wheel and spinning. It has a velocity up to 5 m/s. 
The good point of this robot is in it's shooter (used to throw the ball away 
to the destination). The speed of the ball leaving this shooter is up to 
60 km/hr.  You can shot the target easily with this robot because you can 
adjust the shooter frame to reach the desired destination. We use the 
baseball balls (similar with tennis ball) as the missiles. You can view the 
construction of this shooter from our pictures. They constructed of two 20 cm 
bicycle wheels driven by one dc 24-V motor. We use round belt as a power 
distributor and to get opposite wheel direction.  It use two 24-V batteries 
as a main power supply. We use belt conveyer made from PVC as a ball picker 
with 232 cm diameter. It's driven by one dc motor (second hand motor from
copying machine). It can pick 2 balls in a second. As a ball shooter controller, 
we use solenoide and one small motor dc to put the ball to the shooter. We can 
release the ball one by one or 5 balls in one moment using this controller. We 
hope that next year the organizing committee of ROBOCON 2000 will invite us 
directly to join their 2000 robot contest. Because if we still have to go to
regional contest, we pesimistic that we can do that.  Our team consist of three 
students and one teacher. But we did it with the help of so many students. So in 
this forum I want to say thank you for your support. We also give thank to our 
university that has provided us with their funding and full support. Thank
you, we all love you.  If you have any question about this machine, mail me at
