A Dumper May Be the Best Way to Go…

As we have been going through the brainstorm process, we have realized that you might not need a launcher to get stars and cubes to the far zone. Like many teams, we started out going in the direction of a launcher because of it’s ability to get the objects in the far zone. However, after going through many not so good designs such as a choo-choo, a cut gear launcher, and a launcher with rubber bands, we realized that a launcher may not be the best way to go. Our doubts were confirmed after seeing this design from Singapore:

Notice how at 1:10 one robot dumps a cube over and gets it in the far zone! This has got us thinking. Since there is not that much space in between the far zone and the near zone, you could make a dumper that gets things in the far zone. This would be the best option because dumpers allow you to get more than one star over at once, plus you could get cubes over. This has lead us to another thought. If the opposing team dumps over lots of stars in the last few seconds, you may be helpless because you have a launcher that can only get 1 star over at a time. It really doesn’t make a difference if you can get to the far zone or not, just if you can get objects over and fast. This just goes to show that this game isn’t about strength, but about efficiency.

Intake Makover (February 20, Afternoon)

We really would like to get the intake working by by next Tuesday ( February 23), which will leave us a few days for driving practice and calibrating before states. However, in the morning, Coach Leslie and Elizabeth found that the conveyor was too far forward. This was squishing the ball down, as it was being forced outward. This made the outer layer of the ball flake off a lot when it was forced through the spinner. We couldn’t move the conveyor backwards, because this would require moving the motor, which can’t be done. We decided to put a mini intake connected by chain to the main one, which would move back. The mini intake has flaps, which have more give than the tank tread. This worked great, but the motor that turns the main intake also had to turn the churro and the mini intake. This is too much force for 1 motor. We broke it up so that the big intake and the churro is controlled by one motor, the X-tractor™ is controlled by its own motor, and so is the mini intake.  We spent the rest of the time fixing that. We also made great progress on the churro. Before, the flaps weren’t long enough to push the ball. We changed the churro to chain with big flaps. We also had to take off one to the X-tractor™ flaps, and cut part of the side wall of the ramp because they were hitting.  Overall, today was productive.

Online Challenges! (February 20)
