Saturday 11/30/19 Thankful for Mentors and Coaches helping us get back on track!

Date: Saturday, November 30th, 2019
Agenda: Engineering Schedule/ Priority List
In Attendance: Coach Chad, Coach Cynde, Mentor Chris, Mentor Aidan, Connie, Sean, Hayden, Liam, Tristan and Kairon
Note Taker: Connie
Tasks: Priority List and Engineering Schedule, Review of robot issues and Meet strategy
Reflection: We started the meeting by creating a list of priorities and creating an Engineering Schedule for the next 2 weeks leading up to Meet #2 & #3. Chris helped us create a timeline and make the Engineering Schedule on the whiteboard.

Aidan arrived and we took the robot to the mats to show him the issues we were having like straffing.
We found out that we had 2 of our mecanum wheels on backwards. This was our first fix. Once the wheel placement was corrected, the straffing worked! Thank you Aidan!
Aidan worked with Sean and Kairon on programming limits and corrections for the motors. Liam and Tristan worked on how to correct the arm motors so that the stop points worked better and decided to switch out the core hex motor that controls the grabber with one of the new REV Ultraplanetary Gearbox HD Hex motors. Liam, Tristan and Connie worked to change out the grabber motor Sean worked on setting the new limits for the motor. When we tried to run the motor, it didn't work. We checked connections, programming, and tried the alternate HD Hex motor, then another motor. The regular motor worked properly, which meant the HD Hex motor encoders were failing to work. Sean scanned the internet and Reddit and found other teams with the same problem. He found a YouTube post by FIRST Global Team UK titled "How to fix the encoders on REV HD 20:1 motors 2019". The team stated that they had contacted REV and received the fix from them. We watched the video and decided to try it. It worked! The encoders now function properly with our controller! Just in time to end the meeting! We will add an additional meeting Tuesday after school for testing and adjustments, but at least we know it works. Changing to this motor will give us more power to stop the arm in the positions we need it to stop to grab and move the stones! Thank you Aidan and Chris for helping us troubleshoot and find the answers we needed!
