- Is it mandatory for a robot to have a computer such as Raspberry Pi?
A) Yes, because the computer powers the controller board.
B) No, because the computer is only needed for visualizing the software code on a screen. It may work alone with the controller if a program has been flashed to it.
C) Not really; you could write a small program that controls the robot and flash it to the chip of the controller. Every time you power the robot, it will execute the program in an endless loop.
- What kind of radiation is emitted by the distance sensor of GoPiGo3?
A) Laser
B) Infrared
C) Ultrasound
- Why can't you see the light being emitted by the line-follower sensor?
A) Because the sensor has to be previously activated with a software command
B) It does not emit light but a magnetic field
C) It does not emit anything in the visible range of light
- What is the purpose of the serial port of the GoPiGo red board?
A) To allow us to program it in the same manner that you would use with an Arduino board, where you use the serial port to flash a program to the chip of the microcontroller.
B) To synchronously transmit data from the sensor to the board.
C) To access the serial pins of the GPIO from Raspberry Pi.
- Does an IMU sensor provide an absolute orientation of the robot?
A) Yes, since this is the goal of putting an accelerometer and a gyroscope together.
B) Only if the IMU includes a magnetometer.
C) Only in the case of IMU sensors with six degrees of freedom.
