Robotics Integration by joseph | Jan 19, 2024 | 0 comments 1. I've downloaded my program multiple time but my robot will not drive forward. I have charged batteries and checked the servo ports and values in my program. What is the problem with the robot? The robot cannot drive around with circuits on the breadboard. The servos are in the right ports but they are plugged in backwards. The BOE-Shield has power to the servos turned off. None 2. If you were given the following documentation of the programming commands:Servo motorName Sets the specified motor name to be configured as a servo motor. What would the following line of code do?Servo armMotor; Sets up a servo to be used with a special arm servo horn. Sets up a servo under the name "armMotor" this code won't compile or download because there is no arm motor connected to the robot. Sets up a servo to rotate a limited range of motion. None 3. Which of the following is a reasonable value for this blob? (176, 101, 70, 60) (0, 0, 70, 66) (176, 101, 0, 0) (70, 101, 70, 66) None 4. A ________ allows the robot to detect objects from its environment. Analog Output Resistor Camera Servomotor None 5. What purpose does a programming environment have in a robotics systems? None of the above. It is used to transfer code from a computer to a robot brain. It is used to provide instructions for the robot to carry out. Both of the above. None 6. If you see the following error, what could be the issue? The Arduino is not powered on. You need to power cycle (turn off and on) the Arduino. The USB cable is not connected from the PC to the Arduino. All of the above. None 7. _________ allow multiple electrical components to be connected in a circuit without soldering or special connectors. Arduinos None of the above Breadboards Resistors None 8. What purpose does the chassis like the one pictured serve in the robotics system? It allows multiple robot brains to communicate with each other. It allows the robot to slide with minimal friction. It provides the structure for the robot brain, motors, and additional components. It is used as part of the robotics testbed. None 9. When working with a robot's camera image, a "blob" is a _________ spill on a surface that hardens and becomes gooey. group of similarly-coloured pixels touching each other. group of colored pixels of varying colors. group of similarly-colored pixels that aren't touching each other. None 10. If one (or more) of the robot's servomotors continually move even though you programmed it to stop. What could potentially be the issue? The servomotor plugs are loose. The servomotors need to be calibrated. There is nothing wrong with the robot. The batteries are dead. None 11. True or False. Components in robotics systems can only be physically connected one way, so errors are very unlikely. False True None 12. When configuring color signatures for a Vision System, the entire camera feed is recognise as "Signature 1". What would cause this to happen? More than one color was selected when configuring a signature. The colors of the objects are not different enough for the Vision system to detect. A broken Vision System. None 13. Which of the following is a Digital Output? A Breadboard A Touch Sensor A LED A 3.3V Battery None 14. Why are testbeds helpful to technicians? They allow technicians to write the programs without compiler issues. They allow technicians to test components and the connection between them. They allow technicians to easily verify the quantity of components. Actually, they are generally not helpful to technicians. None 15. Compared to a blob that generate the data (X=90, Y=100, width=63, height=20), a blob with (X=45, Y=100, width=63, height=20) is ___________ the same size but farther to the robot's left. rotated on its side. larger but centred on the same spot. too large and goes off the edge of the screen. None 16. How long would the following command cause the robot to pause before running additional code in the Arduino programming software?delay(25); 25 microseconds 2.5 seconds 25 seconds 25 milliseconds None 17. What purpose does the servo motor like the one pictured serve in robotics system? It connects to the robot brain to keep it from overheating. It allows the robot to move in its environment. It measures wind speed in from the robot environment. It measures how much the robot chassis has rotated. None 18. What should you keep in mind if you are working with a motor layout similar to the one shown? The motors should not be plugged in on "neighbor" ports on the robot brain. The motors are require extra large tires to make the robot move. The motors each require their own power supply. The motors are mounted mirroring each other. None 19. _________ are often used in robotics systems to display what state the robot brain and other components are in. Breadboards Resistors Servomotors Signal or Status Lights None 20. In an image from a Vision System, if one pixel is to the right of another, which of the following is true? It has a lower X-value. It has a lower Y-value. It has a higher Y-value. It has a higher X-value. None 21. Given that the screen resolution is 315 by 207 pixels, which of the pixels in the picture could reasonably be (200, 14)? Option A Option C Option D Option B None 22. Which of these choices is not one of the four pieces of information Vision Systems use to describe rectangle "blob" data? The width of the rectangle (in pixels). The height of the rectangle (in pixels). The Z-coordinate of the center of the rectangle. The X-coordinate of the center of the rectangle. None 23. What benefit does the following microcontroller shield (eg. BOEShield) have to the robotic system? It allows additional circuits to be integrated with the robot. It allows multiple motors to be easily connected. Both of the above. None of the above. None 24. When integrating components in a robotics system and an issue arises, which of the following is an appropriate action to take? Reverse the polarity of the largest component added. Give up, and have purchasing manager order new components. Individually test each component in the system. Switch to a higher voltage power source. None 25. Servomotors allow a robotic system to _________ within its environment. Act Perceive Sense Plan None 26. Robots run programming commands _______ more quickly with the battery pack connected. in sequence, one command per second. all at once, or instantaneously. in sequence, as quickly as possible. None 27. What purpose does the following component serve in the robotics system? It provides the overall structure for the robot components. It allows the robot to play notes and simple sounds. Its springs act as a suspension for the robot's wheels. It holds the batteries that serve as the robot's power source. None 28. True or false. Given the setup, the robot moves forward or backwards when both motor spin in the same relative direction. True False None 29. Flowcharts are helpful tools for _______ understanding how the robot will run a program. None of the above. Both of the above. understanding how to troubleshoot a system. None 30. True or false. When working with the Pixy2 camera, or other similar Vision Systems, "blobs" are always rectangles True False None 31. Which of the following is NOT typically part of the value of an inventory checklist? It displays the quantity of the components included. It displays the cost of the components included. It can be used to keep track of which technician completed certain tasks. It may be used to display important procedures once components are accounted for. None 32. If you were given the following documentation of the programming commands:motorname.attach(port) Sets the specified motor name to be associated with the specified motor port. What would the following line of code do?leftMotor. attach (10) ; It specifies that the left motor is connected on port 10. It specifies that there are 10 left motors attached to the robot. It specifies that the left motor should run for 10 seconds. It specifies that the left motor should run at 10% power. None 33. A microcontroller (like an Arduino Uno) serves as the robot's ________ Brain Structure Programming environment Power supply None 34. Based on this flowchart, what will the robot do if the block's width is 15? Turn motors on. Turn motors off. We can't tell based on the provided information.
