Most of the time when you are swapping motor controllers you are under a time crunch (prepping for or at a competition). Hang on to and test the controllers when you have adequate time to fully test and possibly fix them (for off-season use only) ;)
It's surprising how many speed controllers over the years I have found to be operational that were initially deemed "bad".

How is everyone coming along in getting their bots up and running?

Yes, we did try swapping around pwm cables and ports and determined that the PWM was most likely bad. It was reading 0 volts on the output side as well, and blinking instead of solid.

I think we are getting some borrowed Victors today, but I won't be able to be present tonight.

Re: 2015 MRI

Do you have a spare servo that you could connect to the suspect PWM? (after adding the required sidecar 6V jumper of course)

This could help you determine if the PWM is sending out the correct data and identify the victor as an issue.

If you swapped PWMs with another victor on your board already, then this should have determined this already.

Just my $0.02.

Enjoy!

Since we generally do mecanum we decided to do a 6 CIM shifting WCD robot for the summer project to get some experience with that. We did use our spare pickup arm though so our method of ball pickup is the same as our competition bot. We are entering it as a separate robot so yes, it will be in matches.

What!?! Knightkrawler built a robot that doesn't use mecanum drive! I won't believe it until I see it.

Re: 2015 MRI

MRI was awesome this year! Thanks to 1816 and 2052 for being great alliance partners! Also thanks to 2472 for being an awesome fourth robot! As usual thanks to 2175! It seems like we're either with or against each other in elims in every competition we both attend!

Re: 2015 MRI

MRI was indeed intense and fun to watch during eliminations! Thanks to 1816 for choosing us! Thanks to 4607 and 2472 for being excellent alliance partners! MRI was fun and I can't wait till next year! Thanks to all those competed! Congrats to the scholarship winners from 2175! I hope new members on everyone's team got a taste of what competition atmosphere feels like.

Re: 2015 MRI

Our first time attending MRI was incredible! Thanks for being awesome alliance partners 2175 and 4624, we played some very close matches. Congrats to the champs! This season is going to be competitive with so many awesome teams.

Re: 2015 MRI

Thank You Firebears for such a great event. You were great hosts at a great venue!

I love how Aerial Assist shapes up over the course of the qualification rounds and then really comes to life during eliminations! You can feel the excitement build as the competitors play the quals and really feel out the competition and then come into the elims like prize fighters as the alliances battle every second of the matches.

Thank you 1816 for choosing us, it was the first time we were able to play alongside you in an elim situation and my kids were excited to play with you, 2052, and 2472.

3883 played the elims like a beast. I would hate to be on the receiving end of their charges - awesome drive train!

I loved the fact that the 5 remaining teams from the MSHSL State Tourney all made it into the elims - you could feel the energy in the air during each of the rounds.

This was 4607's first off-season event and we were bit by the bug. Hopefully we are able to make it to Minne-Mini (I registered our team as we were driving back to Becker).

Re: 2015 MRI

HELP! I just realized that we left our gamepiece at MRI:yikes: ! It is pretty unmistakable - it is blue and has our CIS 4607 logo plastered on it. If you grabbed it, please PM me and I will figure out how to get it back.

Thanks!

Re: 2015 MRI

Good luck!!! I'm sure someone already has it.

All in all, MRI was crazy in a good way, especially that final match. Awesome. I'd like to congratulate the two scolarship winners on 2175 and all teams for attending and participating! Also, sorry our lead scout walked off the field. She was too nervous to focus on the fact that you stay on the field.

I wanted to ask, how many teams switched out drive teams for matches, and how did that go? I know when I was Human Player it was slightly chaotic and I have a newfound respect for human players now. (I also noticed about 3/4 through matches a team was looking for their drive team... Hopefully they were found in time)

Re: 2015 MRI

Does anybody know if MRI was recorded and if so where the videos can be found?

4536 planned to have 4 new drivers, but none of them showed up, so we used last year's drivers for all but one of our matches. We did switch up our HP almost every match though.

Re: 2015 MRI

2220 was running an 3/4 new drive team. Last year's driver was coaching and the three new members were switching places throughout the day.

Re: 2015 MRI

4778 rotated rookie drivers for the majority of qualifications and a rookie human player through quals & elims. Good way for new members to feel involved straight away!
