Building/Electronics
The size of screwdriver used to screw shaft collars
5/64
What do smart cables do?
Connect the robot brain to motors; allow robot to function by sending data
What type of paper is an isometric drawing done on?
Isometric paper
How long is each match?
1:30
What is VEX Robotics?
It is an organization that focuses on teaching kids of all grade levels robotics!
A team is considering creating a robot that is faster and a lot more maneuverable. What could they do to achieve this?
Omni wheels, more motors on drivetrain, speed gear ratio, holonomic drive, etc.
A student is running their code (which is guaranteed to work) and notices that their arm isn't moving. The student notices that there is no red light on the plugged-in cable. What should the student do?
Unplug and replug, then change out the cable if it still doesn't work
What things should always go on your header for any notebook entries?
Name, title, date
How many points are taken away if your team is called for ramming?
4 points
What are the 5 steps to the Engineering Design Process?
The other robots on the field easily push around a student's robot. What gear ratio does this student likely have?
Speed gear ratio
What piece of code allows us to stop the arm from falling while it is not in motion (autolock)?
"set [motorName] stopping to hold"
What should be included in a drawing (hint: there's more than just the views)?
Front, right, top, and isometric view; header; labels (i.e. dimensioning)
How can points be won during the competition?
By scoring rings in goals and parking the robot in centerfield
Name all the types of intake mechanisms
Clamp, intake, claw
After using their robot for 5 minutes nonstop, a team notices that their robot is beginning to slow down and is not as responsive. If no part of the robot is broken, what is the issue?
The motors are overheated from use
A student is trying to program an autonomous robot using a distance sensor. What line of comparison code is needed to detect when the robot is 1 inch away from a wall?
"if [distSensorName] object distance in inches < 1"
What is the end goal of creating documentation and keeping a robotics notebook?
Be able to reproduce your robot and remember the steps that led to your final robot
What are some considerations about your robot that should be taken into account during planning game strategy?
How big is your robot? What is your drivetrain's gear ratio? What are you and your opponent's biggest strengths and weaknesses?
The Cal High Robotics Company has many different prototypes to choose from for the creation of their new product. Considering the order of the Engineering Design Process, how can they decide what prototype to choose?
Use a pros/cons table or decision matrix
A student is trying to run their drivetrain and the back left wheels is not spinning. On closer inspection, the student notices that there are no shaft collars present. If the wheel, motor, and controls work fine, what is likely the issue? (hint: is everything connected?)
The shaft is likely not fully inserted into the motor, therefore not spinning the wheel
A team is attempting to program their drivetrain. Although they want their drivetrain to always move, they notice that it stops moving nearly immediately and will not take any inputs after. What single piece of code are they missing?
"forever loop"
A team of students is participating in a local robotics summer camp. Before the competition, what four unique parts to their notebook must they have to be considered for the design award?
1) Labeled isometric drawings, 2) pros/cons tables (or any documentation of brainstorming), 3) build/programming logs and reflections, 4) game strategy plan
In their next match, a team is facing off an opponent with a drivetrain that is geared for torque. What strategies should they use to counteract their opponent's strengths?
Use their speed to maneuver across the field, avoid head-to-head contests
What are the six different topics that have been learned over the course of this week?
1) building, 2) electronics, 3) notebooking (sketching, logging), 4) programming (autonomous and driver, cable management), 5) competition game strategy, 6) engineering design process
