Distance Sensors

Distance Sensors

• Robots use sensors to perceive their surroundings and identify components.
• VEXcode VR allows programming of virtual reality robots using sensors.
• Sensors allow virtual reality robots to behave like self-driving vehicles.
• Distance sensors help robots navigate by detecting their location and obstacles.
• Laser distance sensors measure distance by sending sound waves.
• Laser distance sensors use laser beams to determine distance.
• Laser distance sensors are used in virtual reality robots to measure distances and are located at the front.
• Sensing categories used for programming virtual reality robots include condition interaction, decision making, and action execution.
• Reporter blocks are hexagonal or circular and can be used independently.
• Logical reporter blocks are hexagonal and used to create conditions and results that are either true or false.
• Operations that perform calculations are called mathematical operations.
• Sensing categories contain distance sensor blocks.
• "Front distance is finding an object?" block is a logical reporter that returns true or false based on whether the sensor detects an object.
• "Front distance in ( )" block shows the distance between the virtual reality robot and the nearest object in millimeters or inches.
• The "Forever" block repeats commands and nested blocks indefinitely.
• Comments are text blocks added to the code to make it understandable by describing the blocks.
• Comments do not affect the code.

Eye Sensors

• Self-driving vehicles are automated vehicles capable of sensing their environment and operating without human intervention.
• Self-driving technology relies on sensors.
• VEXcode VR includes unique programming instructions called new programming elements.
• Eye sensor blocks are found in the sensing category.
• "Is ( ) object near?" block is a logical reporter that uses the eye sensor.
• "Is ( ) sensing ( )?" block is a logical reporter that returns true when the front or bottom sensor detects the color.

Bump Sensors

• Collision sensors are used in robots to detect obstacles before collisions.
• Robotic vacuum cleaners are examples of devices that contain collision sensors.
• Collision sensors in robotic vacuum cleaners are typically located at the back.
• Identifying pattern problems is important in programming.
• Examples of collision sensors used in robotic vacuum cleaners include wall sensors and slope sensors.
• Virtual reality robots are equipped with two front collision sensors: right and left.
• A bump sensor block can be found in the events category.
• The right or left collision sensor can be selected from the block's dropdown menu.
• Example of operation category blocks in VEXcode VR are the blocks used in comparative operations.
• Comparison operations are used to compare two values and return a true or false value.
• Logical operations combine two or more conditions and include AND, OR, and NOT operations.
