Componentes de Robotica

Qual tipo de sensor é usado para detectar obstáculos próximos a um robô?

• Sensor de proximidade

• Sensor de longe

• Sensor de distância

• Sensor de proximidade

Answer explanation

Um sensor de proximidade é usado para detectar obstáculos próximos a um robô, pois é projetado para medir a distância entre o sensor e um objeto próximo.

Qual componente é responsável por controlar a direção de um carro autônomo?

• Volante

• Bateria

• GPS

• Câmeras

Answer explanation

O volante é responsável por controlar a direção de um carro autônomo, sendo a escolha correta.

What type of actuator is used to move the joints of a robot?

• Battery

• Servo

• Motor

• Sensor

Answer explanation

A servo is the type of actuator used to move the joints of a robot. It provides precise control over the position of the joint, making it ideal for robotic applications.

How do ultrasonic proximity sensors work in a real-world scenario?

• Ultrasonic proximity sensors work by emitting high-frequency sound waves that bounce off an object and return to the sensor. By measuring the time it takes for the wave to return, the sensor can determine the distance to the object.

• Ultrasonic proximity sensors detect the temperature of nearby objects

• Ultrasonic proximity sensors work by emitting high-frequency sound waves that bounce off an object and return to the sensor. By measuring the time it takes for the wave to return, the sensor can determine the distance to the object.

• Ultrasonic proximity sensors measure atmospheric pressure to determine the distance

Answer explanation

Ultrasonic proximity sensors work by emitting high-frequency sound waves that bounce off an object and return to the sensor. By measuring the time it takes for the wave to return, the sensor can determine the distance to the object.

What is the difference between a servo motor and a stepper motor?

• A servo motor rotates clockwise and a stepper motor rotates counterclockwise

• The difference is that a servo motor rotates at a specific angle based on the control signal, while a stepper motor rotates in discrete increments or predefined steps.

• Both types of motors rotate in discrete increments

• The difference is that a servo motor is more energy-efficient than a stepper motor

Answer explanation

The difference is that a servo motor rotates at a specific angle based on the control signal, while a stepper motor rotates in discrete increments or predefined steps.

Why is it important to correctly calibrate proximity sensors?

• To ensure accurate measurements and avoid false positives or negatives in detecting nearby objects.

• To confuse users and generate errors in detecting nearby objects.

• To increase the energy consumption of devices for no apparent reason.

• Because sensors work best when they are misaligned.

Answer explanation

To ensure accurate measurements and avoid false positives or negatives in detecting nearby objects.

Qual é a importância do feedback nos controladores de movimento?

• A retroalimentação não é necessária nos controladores de movimento

• Permite ajustar e corrigir o desempenho em tempo real.

• A retroalimentação não tem impacto no desempenho dos controladores de movimento

• A retroalimentação só serve para complicar o funcionamento dos controladores de movimento

Answer explanation

Permite ajustar e corrigir o desempenho em tempo real.
