I read this post and after a bit of searching didn’t find a thread dedicated to defining all of our special acronyms and phrases…
I figured better late than never so I will start us off
B.L.T. - I don’t remember who came up with this one (I want to say Rick Tyler) but it is brave little toaster used to describe robots that aren’t much more than a Proto-bot chassis and a simple mechanism.
Descore - An awkward way to express the simple concept of removing an object from a location where it would be worth some points at the end of a period of play. i.e. When Johnny’s robot removed the balls from the goal, Jane exclaimed that the balls had been descored; and then she had to explain to her aunt that “descoring the balls” simply meant removing the balls from the goal.
Nonadrive- a drive train that can swap between 2 different styles of driving. such as tank drive and holo.
Mecanum wheel-somewhat like an omni wheel, but with the rollers being at 45 degree angles. 4 of these in a tank drive setup give a robot strafing capability when the front wheels and back wheels spin in opposite directions.
PID-stands for proportional integral derivative. is used in programming to control the robot based on what it did, what its doing, and what it will do.
Hmmm. I feel as if the things I chose to define are a bit outlandish. perhaps its just me.
I think you have mistaken an implementation “detail” for the root reason for calling a drive train a “Nonadrive”.
The FRC team that recently called their popular drive train a nonadrive definitely could switch between two sets of wheels; but I’m pretty sure the reason they called it a nonadrive is because it used a total of 9 wheels. The prefix “nona” refers to 9 of something.
To double check my belief, I looked up this Wkipedia definition of the word “Nonagon”.
“In geometry, a nonagon is a nine-sided polygon. The name “nonagon” is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, …”
So, while making good use of 9 wheels in a STEM Robotics machine might often involve putting them on the ground in groups of 4 and 5, it isn’t the reason people have been calling (or should call) some 9-wheel drive trains nonadrives.
Anyway we know our “Nonatread” does not meet definition of the dictionary since there isn’t 9 of anything on it… But In the spirit of 148 it was deemed the “Nonatread” simply to show where the inspiration for the design came from (mostly 148’s first prototype of the nonadrive back in 2009 or 2010 forget when). Anyway thats our method to our madness.
It looks like I am not able to edit the first post. I was hoping to compile the list and continuously update a master list in post 1 of the thread but unless I am missing the way to edit it or an admin can help me out here I am going to have to just post the compiled list as just another post.
Here is the fist compiled list. It is just alphabetical now but once we finish it I will arrange it into subgroups.
BLT - Brave little toaster used to describe robots that aren’t much more than a Proto-bot chassis and a simple mechanism. CG - Center of Gravity Descore - removing scoring objects from a goal DT - Drive-Train FRC - FIRST Robotics Competition Game-Break (Choke Hold Strategy) - A strategy that basically guarantees you the win. (Dumping goals under the ladder) H Drive (Nonadrive, Slide Drive, Kicker Drive) - Holonomic that consists of a 4 wheel tank style drive and one or more wheels in the center for strafing Holonomic Drive (+ Configuration) - Holonomic drive where wheels are mounted an the 4 sides of the robot Holonomic Drive (X Configuration) - Holonomic drive where the wheels are mounted on the corners at 45 degrees HS - High Strength (HS motor is a motor 393)
**Kiwi Drive **- Holonomic drive where 3 omni wheels are positioned evenly 120 degrees from each other. Mecanum wheel- somewhat like an omni wheel, but with the rollers being at 45 degree angles. 4 of these in a tank drive setup give a robot strafing capability when the front wheels and back wheels spin in opposite directions. PID-stands for proportional integral derivative. is used in programming to control the robot based on what it did, what its doing, and what it will do. Pot - Short for Potentiometer Strafing - Robot movement in the side to side direction
**Ultra **- Short for Ultrasonic Sensor VRC - Vex Robotics Competition
This type of list is perfect for the Wiki, since it can be kept up-to-date, and anybody can contribute. I’ve started a page here that I’ll keep cleaning up till I’ve got all the pre-existing terms integrated. Some of the terms will just be explained on the page itself, and some will link to wiki pages with more in-depth info.
Dumping goals under the ladder is not a chokehold strategy.
A chokehold strategy is a strategy that guarantees a win virtually independent of opponent actions. In Round Up, teams could descore or drive under the ladder, or they could dump their own goals, or they could play defense. Good strategy yes, chokehold not.
