Which of the following is a sensor used by a robot to detect if there is an obstacle along its path?

• 
• 
• 
• 

Answer explanation

An ultrasonic distance sensor is used to measure the distance of the object from the sensor using SONAR by emitting ultrasound at 40kHz or that travels through the air and strikes the object on its path. The rays bounce back from the object and then back to the module.

In block coding, what can make a "sprite" or a simulated robot perform the same motion repeatedly?

• variable

• set variable

• conditional

• loop

The main goal of visual programming or block coding is to make programming more accessible at 3 different levels. One of which is the use of block/icons, diagrams, and forms to eliminate syntactic errors. The level described is known as ___.

• semantics

• simulation

• syntax

• visual language

Answer explanation

According to Block-based coding (codejig.com)

"The main goal of visual programming is to make programming more accessible at 3 different levels:

Syntax – the use of block/icons, diagrams, and forms to eliminate syntactic errors.

Semantics – usage of meta-information to document and explain the program.

Simulation – visual programming languages may include visual mechanism to bring the program in a particular state and check its behavior."
