Read how Teams 1540, 2517 & 2542are using Science, Technology, Engineering and Mathematics (S.T.E.M.) as they build this year’s robots:
Robotics fever is running high in FRC 1540’s lab. Because of Martin Luther King Jr. Day followed by teacher report-writing days leading up to the second semester, we had a five-day weekend at our disposal. Several members have spent time in the lab for all of the last 14 days! Last Saturday and Sunday marked the final days to prototype our ideas. On Monday morning, we held a design meeting, confirming a final robot design that achieves the goals we put forth, and still remains simple enough to finish on time.
Our design prioritizes shooting, especially in autonomous. We plan to ignore upside-down frisbees, as our testing showed they almost never fell upside down. We will also hang on the first level of the pyramid, and have a potential second level climbing method that we will implement if we have the time. As has been our custom for the last four years, we are once again making a “prototype” robot along with the more polished competition robot – once the latter is in the bag, we can keep the former for more software work and drive practice.
This game is unlike anything we have ever experienced, and offers a whole new slew of challenges. Still, we drew considerably on previous years of experience, prototype subsystems, and feature feasibility to decide on a final design. The ability to choose a well-considered path is an integral part of applied science. FIRST is the primary way for students at Catlin Gabel School to get hands on experience with the applied sciences, and especially engineering. Thanks, FIRST!
Once upon a time the Green Wrenches had to learn to use a new electrical communication system called CAN bus. After we tried to figure it out alone over about five meetings. We realized we needed help, while discussing our issues, one of our mentors mentioned another team’s mentor that may be able to help us. We contacted him.
After an hour and half on the phone and him coming in and helping us for a meeting, we are now fully functional! We wouldn’t have been able to accomplish this without the help Steve Error Code Xero! And electronics lived happily ever after.
During the third week of the FRC, team 2542 has had very little problems. Our first and foremost problem is getting the frisbee launcher to send the disks flying high enough to go through the goals. According the mentor Don of Microchip, there aren’t many problems at all. The mechanics team just needs to figure out the launching angle, as well as the type of motors that will work best for our design. Mentor Eric from Boeing has also added that the problem was being solved by using physics to calculate the amount of force the motors need to exert to properly shoot the frisbees. He has also added the mechanics team had to use four bars to stabilize the angle of the shooter. Both mentors agree that it was essential geometry to calculate the shooting angle. Team members Abner V. and Alex M. both agree that the major problem was the shooting and angle, as well as design. However, they both added that it was a bit difficult to plan the electrical board out without all the essential parts placed on the robot. Our mechanics team has also been using the web as a way to collect ideas for the shooter.
By using the physics, online resources, engineering ideas and math, team 2542 has managed to almost fully solve all our build issues as the third week finishes.
