What will be the next technical growth leap for the average team?
I like my field carpet without oil slicks, thank you very much.

Re: What will be the next technical growth leap for the average team?
I think in the next 4 years, lidar technology will get cheaper and more teams will pick it up, hopefully spurred on by a game that is designed to have a longer auto with less uniform targets.
I think the next big hardware leap would be Brushless motors. I think we're ready for that now, just need someone to make a proposal that satisfies the powers that be. |

Re: What will be the next technical growth leap for the average team?
GPS. All you need is a few sources of signal.
The FMS system provides one signal source. Being able to lock onto a few more (cell phones?), and you could have a pretty good estimation of where you are on the field. Working around R68 would be needed - no form of wireless communication to, from, or within the robot. Visible spectrum and non-RF sensors are allowed. With RF being 3 kHz to 300 GHz, you could try to make something outside of that range to send a time mark. For this year's Airship, we are working on Doppler Radar, however, we don't see that as being useful for future games. |

Or IR tracking like the HTC Vive, with the field having the tracking stations set up and having the sensor array in the KOP. It could be like the 2012 Kinect station, but less gimmicky, using technology that actually works, and with more applications in the field of robotics.

Re: What will be the next technical growth leap for the average team?
The three biggest advances in the last six years or so are:
Swerve-in-a-box for less than $100/module, requiring nothing other than attachment to standard VF to make a drivebase, would change mobility. I think that's coming. |

Re: What will be the next technical growth leap for the average team?
The next big step is going to be the continued development of consumer-grade machine tools. Additive manufacturing capability is already percolating down to the hobbyist and prosumer levels, and teams have adopted that technology already. As we see similar developments in affordable CNC mills/routers/lathes/combo machines, I suspect we'll see significant strides in machinery capabilities of teams who work out of classrooms and garages.

Re: What will be the next technical growth leap for the average team?
I think we might have different definitions of the word fun. Personally my definition does not include unnecessary field delays (we get enough necessary ones as is). I could definitely see this happening though, provided someone can come up with a system that might be less susceptible than the current pneumatics system to leaks. I can't say I know enough about hydraulics to know how likely this is to happen, but the visceral "I don't want fluid all over my field and someone else's robot" reaction is, I think, going to stick around until someone proves there's a workable solution.

I think localization is going to get there sooner rather than later. I know a few teams that have been experimenting with it in FTC using the image targets and Vuforia, and I could imagine a similar scheme being used in FRC. FRC/competition robotics fields already have a number of features that make them much better for this than "real-world" scenarios, so it's really a matter of either the commoditization effect that you mentioned or FIRST making things a little easier for teams. As a side note, I would love to see a challenge eventually, once localization becomes more mainstream, where mapping is a significant challenge in a longer autonomous period. Perhaps a semi-randomized field, not quite like Stronghold, but similar. Something else that might become more of a mainstream over the next few years is roller-sized mecanum / "vectored intake" wheels. We aren't quite at the point where they're commodity for FRC (given most of the teams that use them like this are using 4" versions), but I think that will get here soon too. Not quite as far out as anything you've mentioned, but I also don't think they're really highly accessible to average teams yet. I suppose that isn't a leap so much as a step forward, though. |

Code:
import swerve from _future_ There's still UX issues with them but, tbh, there's similar UX issues with most drive systems in FIRST. That'd be a great place to see some innovation - the UX of the operator control. CheezyDrive (SplitArcade) seems to be a good solution for tank drives in that it discourages the Drive, Turn, Drive, Turn approach that is brutal to drive systems. I'd really like to see some dev on similar things for mecanum to address the fact that sideways motion is expensive and as you are driving it auto rotates you drive wheels into position. |

Re: What will be the next technical growth leap for the average team?
The next advancement will not be technological, it will be cultural.
With permanent full FRC fields becoming more and more prolific, access to events, both official and unofficial, will increase dramatically. This will create demand for mass media coverage, switching from "aren't these cute kids and their cute robots cute?" to actual game reviews, results, and prognostication. |
