What is Firmware?A special type of software that allows the EV3 to understand the programs you writeA special type of software used by law firmsThe parts of the robot that are not flexibleThe physical appearance of the robot4. What software do you use to download firmware onto the robot?The special EV3 Firmware Downloader app for mobile phonesThe Introduction to Programming: LEGO MINDSTORMS EV3 curriculum The EV3 Programming SoftwareThe firmware can only be updated at the factory5. Where in the software is the option to download firmware?In the Tools Menu, under Firmware UpdateOn the main menu, as a button marked "Download Firmware"In the EV3's on-screen menus, under "Firmware Tools"In the lesson pagesEV3 PROGRAMMING SENSING, PLANNING, AND ACTING / EV3 SOFTWARE:1. What does "Programming is Precise" mean?The robot will always move to the precise location you wantYou need to tell the robot precisely what to do, or it might not be what you wantedIf you do not type the commands exactly as shown, the program will crashThe robot will do precisely what you want, even if you give it the wrong command2. What do Sensors do for a robot?Provide power to onboard electronicsCreate a physical effect like turning a wheelProcesses data and makes decisionsGive it data on its position and surroundings3. What does a robot's Program do?Provide power to onboard electronicsCreate a physical effect like turning a wheelProcess data and make decisionsGive it data on its position and surroundings4. What kinds of Actions can a robot typically take?Provide power to onboard electronicsCreate a physical effect like turning a wheelProcesses data and makes decisionsGive it data on its surroundings5. What is to "Break down problems"?Split up a big problem into smaller ones that are easier to solveSolve the problem all at onceGive up because the big problem is too hardTechnical difficulties with the robot6. What does "Build up Solutions" means?Build a fully working solution by expanding upon partial solutionsThe best programs solve every problem at the same timeBuild your robot starting with the wheels and working your way upwardD. Accumulate a lot of chemical compounds7. Which of the following connection types allows you to download programs onto the robot?USB cableEthernet cableIR connectionPower cableWhat advantage(s) does a "model"-based understanding have over just memorizing facts?You can learn a "model" faster than memorizing every single factYou can reason about new situations, even ones you haven't seen beforeModels make things make senseAll of the aboveWhat is the "Program Flow" a model of?Unrelated blocks in the programming softwareProportional reasoningThe way a program runsBottom of FormSensing, Planning, and ActingWhich of the following is NOT true about Computational Thinking?It is applicable outside of computer programmingIt includes the idea of using models to understand systemsIt is used in roboticsIt refers only to the process of writing code for a programWhich of the following will help you navigate around a large program?Scroll arrows on the sides of the screenZoom controls in the top-right corner of the windowArrow keys on the keyboardAll of the aboveHow do you add a comment to your program?Start typing on the keyboard and a comment will automatically appearClick the comment tool to create a comment box, then type in the box to add a commentRight-click a box and select Add CommentThe EV3 software does not suppose adding comments53340295275Indicate the name of the following block configuration or settings: The following block is an example of which kind of programming block?2118360180340SwitchLoopMove SteeringMove TankWhat kind of programming behavior is the following?36118805270500Switch inside a LoopLoop inside a SwitchLoop controlled by Ultrasonic SensorSwitch conditioned by a Rotation SensorWhat control method is used to condition the following Loop Program?19812005651500 CountLogicSensorRotationWhat do the following eight blocks in the EV3 brick’s screen represent?655320328295INTRODUCTION TO ROBOTICSMatch by completing the blank spaces on the right with the numbers on the left1Program_____Responsible for identifying a task and planning a solution2Programmer_____Brain of the LEGO MINDSTORMS system3Brick_____Input device that allows robots to interact with its environment4Sensor_____Follows a plan5EV3_____Actions or tasks a robot must do6Robot_____LEGO MINDSTORMS language that translate instructions from human to robot7Behavior_____Instructions written to follow a plan or course of actionWrite True or False___Robotics is the science that studies robots___Robots are made to perform useful tasks to make human life easier___Motor ports are identified using letters___Sensor ports are identified using numbers___Some examples of behaviors are moving, stopping, and turning___Using proportional strategy is better than the guess and check method___Variables store data for later use___A Threshold is a cut off value to allow the robot to make decisions___In a Turn in place both wheels rotate in opposite directions___In a Wide turn one wheels stops and the other rotates___To iterate means to test every step of the way___Pseudo code is a common practice in coding to help read and understand your programs___The wheel with the lower power in the Move Tank Block determines the direction of the turnSENSORS:1-It is an intelligent, computer controlled LEGO? brick, which is the brain of the LEGO MINDSTORMS?Education robotA.ProgramB.
