Choosing how to use the Picaxe-28X
May 20, 2008
Hey, I'm new to this site - obviously. I created a rather beautiful robot in high school in the FIRST robotics league and worked with the programming, wiring, and mechanics of the robot attached. plus I was the leader of the team. I have also worked with soldering and circuitry in the past but am not perfect at it and I can use a breadbord rather well.
Now you know what I have done so you can help with my decisio. I am planning to get the Picaxe-28X. I have decided I can handle an Non-OOP language (I like Java) and will go with the cheap and easy to start with. I have been looking at three different versions though: The IC, The Project Board, or The Experimenter?
The Project board seems easier to add things like motor controllers because of the additional slot, but I am not sure which is better the Pololu or the L293D. Also I am not sure if the extra, pre-attached tidbits on the Experimenter will be helpful enough to warent the extra money. I would like to keep this as cheap as possible without getting in over my head.
Lastly and leastly, serial or USB. which is better for modern computers. there is like a 10$ diff. but is it at all important.
Finally, am I just going about this the wrong way entirly and need to re-think things (Suggestions required if so)
2004 – Ragnar:
This robot is designed to cap the goals with the 36” diameter to multiply scores. Our robot was also capable of pushing small goals into the scoring areas.
|Weight:||130lbs (after 4hrs of work on practice day)|
|Dimensions:||32” x 28” x 60”|
|Drive System:||2 wheel drive (Bosch Drill motors) with casters|
|Manipulators :||Scissor lift with pneumatics claws attached|
|Strength & Weaknesses:||Our robot did not break or burned any component on the field. The scissor lift was very slow. It took 30s to reach the maximum height. Caster wheels made the robot difficult to control.|
|Autonomous Strategy:||Grab the multiplier ball ASAP.|
Programmed with some varriant of C-script. controlled with 3 joysticks: tank style with the third for extra functions like the scissor-lift and the arm (controlled by a different person then the driver). back had caster wheels and the arms were opened and closed by Pnematics.
the main motors were rather powerful drill motors attached to a gearbox designed for torque and control.
This robot was in the San Jose Competition in 2004 and came in 42nd. not bad for my schools Virgin year and for our first robot.
