Otherwise this is going to be a tough choice.

Will be recorded again if I don't make it to this session?

As OP said, the sessions will be recorded this year - I'm planning on watching one of the two as well :p

And the great news is that all Championship Conference talks will be recorded this year, so you don't need to choose between this session and Karthik's...you can have both!

Our main problem is how long it takes to process an image. By the time you process the image. The robot is somewhere else.\

Do you know if the speaker will be fitted with an on-person mic that feeds electronically into the recorder? Audio quality from acoustic pickup from an on-camera mic at the back of the room is close to inaudible for those of us with aging ears.

One question that I hope you will cover is:

When to use vision and when to not use vision. Last year, we had a mentor work on tracking the yellow totes for a couple of weeks and we didn't end up using it at all. :/

However, this year you need vision tracking if you have any hope of shooting a high goal in autonomous.

Thanks,
Drew

While this is not a strategy talk first and foremost, we will most certainly discuss this. In particular, we will look back at the history of vision in FRC and you will quickly notice how often the vision challenge is a diversion for the majority of teams.

I thought I'd share a clip we took today prepping for this conference presentation. We will definitely be going through all the pieces it takes to get a robot tracking like this!

I think it will be addressed, but I would be curious to hear exactly how much control on 254 is done by drivers vs with vision. What are your failsafes if the vision board suddenly crashes/shorts/explodes?

The operator holds a button saying they want to auto aim, and the driver holds a button saying that it's okay to shoot. Everything else is autonomous.

Hmm - including sensing on the intake and ball pre-positioning?

Do you guys find that it's easier to accurately position the turret than it is to turn the drivetrain? That gif is really impressive, and I'm wondering how much of that is the turret being mechanically easier to control. Do you do any motion profiling on it, or is it just PID?

I'm looking forward to your talk!

The turret is just running position PID (onboard a CAN Talon SRX). Turrets are much easier to control than a drivetrain (inertia, friction, and skidding are basically non-issues).

Are you having a tough time coordinating vision with motion?


Does buggy vision make your robot grasp at things that aren't there?


Do you wish your robot had superhuman powers of perception and control?


If so, join us at 7:00 PM on Wednesday, April 27 in Room AC265 of the America's Center at the FIRST Championship for our session on "Integrating Computer Vision with Motion Control".

Here's the abstract:


This will be presented by Jared and Tom from Team 254, who (together with Austin from Team 971) brought you Motion Planning and Control for FRC last season. We had a great response (and a packed house!) last year, and have incorporated your feedback to make this session even better. To ensure the session is approachable for all levels of experience, we plan on focusing on concrete FRC problems (like auto-aiming a shooter) while showing how concepts like understanding how your camera works, being smart about tuning your vision algorithms, utilizing kinematics, and applying motion control best practices can make your solution better...we want to help teams compete while also opening your students' eyes to how professional roboticists approach similar problems.

And the great news is that all Championship Conference talks will be recorded this year, so you don't need to choose between this session and Karthik's...you can have both!

One way or another I will make sure a recording of this session (of sufficiently high quality) gets posted online. We will just redo it from home (and answer the questions that we received in person) if necessary.

Jared and Tom, thanks for a great talk!

How much does your turret tracking degrade with that kind of lower performance? Or does the latency compensation and high quality construction of the turret compensate for that?
