SCRC (Saskatoon Combat Robotics Club) / Parade Plans
« on: July 25, 2017, 03:16:55 pm »
I double-checked and we have been accepted for the parade this year. (2017)

The parade is Tuesday Aug 8th.  Registration is 7:30-9:00am.  We MUST be registered by 9, so I guess that means we shouldn't just show up at 8:55.  The parade actually starts at 10am.

Our tow vehicle MUST be decorated.  Do we want to make bows out of caution tape again?  Buy some metallic poofy flowers?   "Decorated means flowers, balloons, artificial skirting, etc. -- not vehicle decals"

Bring your own water. 

Who is in this year?  Do we have any large drivable bots that can follow behind the arena?  Will someone build an angle grinder to block of flint bot to make sparks?

Scott, these are all control box related.  What do you need to make them happen?

4. A new control box that can run fights independently of a laptop (but can still take laptop inputs, etc).
This is actually in slow progress.  I got a donated Pelican 1400 case with panel frame.  This is exactly what I wanted, so I'm happy about that.  I have started ordering parts to build an entirely new control box.  My initial goal is to build an exact replacement but better, and with expansion thought in.  The "run independently" is a good goal, but I'm not sure how achievable it will be before September.  It will require a complete rework of both the computer software and the box firmware.  I want to see that, but I'm going to suggest we don't attempt to do it for September.  One of the bits that will make this possible is the addition of an LCD screen to the box.  That is in my initial plans.

6. Audio system with cues from the control box
I'm considering this and it will be an addition to the new control box when it happens.  I don't think we need much for this... a chinese computer controlled mp3 from sd card player is only a few bux.  I probably have a few in my junk bins already.

1. ...displaying schedule, brackets, and highlight videos (on the TVs).
This is done already, isn't it?  Do we need to tweak it or add something?

Quote
5. New arena lights - 12V RGB LED strips that can be controlled via control box.  Possibly individually addressable.
are we married to the idea of RGB for the general lighting?  I haven't actually researched it, but my hunch would be that RGB aren't as bright as just normal white LEDs.  I love the idea of colour accents, but could that be a separate thing from the boring white lights?

Quote
7. Run permanent ready/tap out cables inside frame with connectors on the end.
I'm putting this on hold until I've had a chance to start testing out the RS485 stuff.  If we can wire everything RS485 it will make wiring so much simpler.

11. Hazard motors run from ESCs
I have all the bits.  I just need time on the arena.  Maybe need to discuss options, here, too.  Do we keep the solenoids in addition to ESCs?  Do the solenoids act as the "safety" cutoff? (see next question)

Quote
13. Door lock interrupts so the control box can disable hazards and not start fights until locked.
I have no idea what we would need for this.  Some sort of mechanical or opto switch that is triggered either by all four doors being in position, or of the two pins being in position.  In my opinion, this should be readable by the control box, but they should also disconnect the hazard motor drive somehow outside of software.

17. 3 judging tablets/phones, tied into the laptop software.
15. Ref controlled count-out trigger
This will require tablets, and Nathan and RevEng to coordinate on getting it done.

Travis: the existing clock could definitely switch to a count-out mode.  What would be a good visual cue that it's no longer match time?  Should it refuse to count down a countout if there is not enough match time left?

Thanks Nathan... I was already formulating my reply before I read yours.  Yes, the judging tablets could certainly trigger the "show motion" countdown.  Maybe it could be a two of three situation.  Do we need another "shot clock"? or would audio cues be cool for this?  Can we hire Allison Smith to do all our audio voicing?

SCRC (Saskatoon Combat Robotics Club) / Re: Non-wheeled rule 5.1.2

I suppose that's a fair question.  It very clearly can travel forwards and backwards.  I guess I would consider that "visible and controlled mobility."  If you guys want it to very clearly be able to turn left and right... well, then it probably won't qualify.  I can make it go left or right, but it certainly won't turn on a dime.
I'd argue it's as mobile as Wrecks.

SCRC (Saskatoon Combat Robotics Club) / Non-wheeled rule 5.1.2
« on: August 18, 2015, 01:08:40 am »
Before I go to a lot of effort building a 2lb walker, I would like to confirm that this method of mobility would fall under rule 5.1.2 Non-wheeled and get the 100% weight bonus:

In a resting position, the bot has two "legs" in contact with the floor at four points.  The back leg tilts the entire bot left and right.  The front leg tilts with the bot and only one side of it remains in contact with the floor.  The front leg has rubber feet and pivots in order to drag the bot forward. (or push it backward)  The rear leg then tilts the bot the other way, and the front leg pivots back, completing one walk cycle.  By adjusting the gait, I am able to cause the bot to trend left or right. 

There are NO rolling elements in contact with the arena floor.  There are no continuous motion motors involved in the motion of the bot.  (aside from the incidental gyroscopic precession of any spinning weapon)  The motion is entirely caused by two servos which pivot back and forth in the proper pattern.

See the proof-of-concept in action here: https://www.youtube.com/watch?v=g6Q2B_kZzX0

Is this good?

I am willing to have the discussion of whether this will qualify as a rookie or as a masters, but after we answer this first question first.

Rachel says "Sure" so she will be there with her 1lb rookie (I think she still qualifies as rookie).
