University competiotion... This will be there I hope... suggenstions needed and are welcome...
Just for fun, don't know the prizes, but :) I decided to enter. After reading a lot about robotics, and I love it anyway... I'm at University of Oradea, first year but I think that this would be a good starting point for me...
So...
- Wheels
All I want is a line following robot. I want it verry cheap... First time I got on working on the gear... After disansambling some LEGO toys, I got on some wheels... from LEGO Tehnics I got two 68.8x40mm wheels which I think are too large but another 30.4x14 will do the work... I won't use any gear ratio just the direct power of the motor...
- The gear motors
I stop thinking about where to buy some gear motors... I saw solarbotics Gm8 but I thought that are expensive for this project... After some thinking, I found under my bad two old CD-ROMs... Man... those has gear motor for the doors and for the CD spinning... I disansambled them and :D voila... 4 motors... 2 were the same... 1 was flat motor... and another a horizontal cubic motor... so got two same type motors... The only problem was the axis... it was 2mm... my wheels had round 6mm holes... so I got a gear motor... heated up until it was red and started to make a hole in an adapter from LEGO Tehniks :P now those wheels fully funcional... not the stable one :) but I think it will do the trick
More later... after buying some parts
