View this email in your browser

Lone Star Central Regional

Spectrum 3847, the St. Agnes and Strake Jesuit engineering team, was the recipient of the prestigious Quality Award at the FIRST FRC (For Inspiration and Recognition of Science and Technology) and a Regional Finalist at the Lone Star Central Regional Tournament held at Strake Jesuit College Preparatory.

“We are honored to have received the Quality Award sponsored by Motorola Foundation. The award celebrates machine robustness in concept and fabrication. Our robot Gamma was built with a very detailed plan in mind to withstand the rigors of competition. FRC is often called the “the hardest fun you’ll ever have. ” said Spectrum 3847 Coach/Mentor Allen Gregory. “In addition, the team won the Engineering Inspiration Award at an earlier tournament and came away with a berth in the 2017 FIRST World Championship. We look forward to the global competition George R. Brown Convention Center in Houston from April 19 to 22, 2017.”

Spectrum 3847 was ranked 3 with a record of 12-5-0 and advanced to the finals in an alliance with AwtyBots #5829 and Screaming Chickens #3997. They formed a strong alliance and worked their way to the finals. ​They lost the finals to three award winning teams Robonauts #118, Texas Torque #1477 and TCAT #5526. All six teams will join the global competition at the Championships in April.

Day 48: Recap

So we had a bit of break but we'll try to keep things updated as we move through the competition season.

Week 6
Here is the state of the competition robot that we bagged. We didn't really get to perform a full system check on it but we are confident the subsystems work.





Gear Intake
We are very pleased with the state of the gear intake. We have the control system working on it so their automatic gear pick up routines that lower the gear intake, spin the intake wheels and pickup the intake once the driver drives it into a gear. We were looking into using an IR proximity sensor to determine when we had a gear but it was having some difficulty getting tuned to the right distance so instead we realized we could just determine when the roller starts drawing more current which means the gear is fully back to the roller so the motor become the sensor. We are also adding some protective Lexan to stop the gear intake from damaging itself. We are also adding some additional roller tube to the intake that allows us to intake the gear when it comes in further to the side of the intake.

Look at check_in episode 7 for a better description of the past two weeks.

Build doesn't end
The competition robot may be in the bag but build season isn't over. We will continue to iterate on our design for the next 8 weeks until Houston Champs.

“Engineering is a great profession. There is the satisfaction of watching a figment of the imagination emerge through the aid of science to a plan on paper. Then it moves to realization in stone or metal or energy. Then it brings homes to men or women. Then it elevates the standard of living and adds to the comforts of life. This is the engineer's high privilege.” - Herbert Hoover

Day 32: Sheetmetal should be in tomorrow

Look for our big blog post tomorrow night after we get our sheetmetal back.

We have been preparing all our parts to assemble the robots once we get our parts back tomorrow.

We have been printing parts including a nice camera mount.


Also preparing our shooter motors with encoders and making the cabling nice and neat.

Day 30: Superbowl Bot Building

We are still working on getting our parts ready for the sheet metal delivery.

We have our gears and wheel modules ready to be bolted up to the sheet metal when it arrives.

We also have powder coated Versaplanties for the competition robot ready to go as well.

- Spectrum


“The implication of this might surprise you, though: when the tough parts come along, the rejection and the slog and the unfair bad breaks, it makes sense to welcome them. Instead of cursing or fearing the down moments, understand that they mean you've chosen reality, not some unsustainable fantasy. It means that you're doing worthwhile, difficult work, not merely amusing yourself.” - Seth Godin

Day 29: Adventures in Making a Rack and Pinion

Now that sheet metal has been sent out, it's finally time for us to buckle down and figure out some of the smaller parts on our robot. Among these smaller parts is the plate we plan on using to cut off individual lanes in our three-wide shooter.

CAD model for said plate

Our plan for actuating this plate was to have it driven by a REV Smart Servo mounted in the inside of our shooter tower via a rack and pinion. This seemingly simple task proved to be the cause of numerous attempts to fix open contours in Solidworks before realizing that rack teeth do not, in fact, use the same profile as gears and are simply trapezoids. With the annoying geometry problem out of the way, the question then arose of how to know what dimensions define these trapezoids. The annoyance was further exacerbated by REV's use of the metric module to define their tooth spacing instead of the diametrical pitch more commonly used in the imperial world. 

After a number of google searches (including re-learning what such technical terms as "diametrical pitch" even mean), we eventually discovered a useful whitepaper on the Iowa State University website which outlines how to design gear and rack teeth given certain parameters for your tooth profile. After copying their spreadsheet maths into our Master Sheet, we were able to successfully model our rack. A copy of our spreadsheet can be downloaded here.

"I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing. Only I will remain." - Frank Herbert
