I really hate to be “that guy” complaining and cutting down team’s work - but please post some disclaimer or warning about the rapid flashing / strobing throughout the video. People are sensitive to that sort of thing, whether it’s as serious as epilepsy or even as mild as getting headaches, and it comes off as a surprise.
In general I didn’t really think the flashing effect added much - just made it harder to see - but I respect the stylistic choice and just hope that you can add a warning or disclaimer to the video or post.
I would like to apologize on the behalf of my team for anyone who’s sensitivity to strobe lighting may have been triggered by this video. It was reviewed by mentors and leads before posting and it was an oversight on our part. Our student Director of Media did a great job of editing is possibly working on a less flashy update today that we will post that if it gets is done. We still wanted people to see our reveal in the mean time, so a warning has been added to the YouTube title and in the original post. Thank you all for your feedback and kind words!
@anihtA Awesome video! I notice your robot is using similar pistons for the climb from last year. Could you send me a link to the pistons FRC2910 used? I am very intrigued by their strength in lifting 125lbs!
We are using impact-resistant 1-1/2" bore cylinders from McMaster-Carr. This year’s are 23" stroke and last year we used 20" stroke. The cylinders alone do have enough strength to lift the whole robot at full pressure, but we added constant-force springs to help keep it consistent.
I don’t think we ever weighed the cylinders separately from the rest of the robot. I can say they weigh substantially more than standard Bimba cylinders of the same bore and stroke.
I would assume single solenoids, which have a default position. This would mean that they would retract whenever the robot is disabled. We use them on out intakes and on our climb to save PCM slots.
