Virtual Robotics Presentation

Virtual Robotics

The VEX VR Robot Electromagnet is located at the front of the robot pointing down towards the Playground currently in use.

Robot Features

Robot Physical Attributes

The VR Robot has the following physical attributes to scale:

• The wheels are 50mm in diameter.

• The wheelbase (the distance between the center of the front wheel and the center of the back wheel) is approximately 50.8mm.

• The VR Robot’s length is 133mm.

Robot Sensor

Programming Language, Behavior, and Commands

• A programming language is a set of rules in which symbols represent actions.

• Behaviors are actions performed by a robot defined by the programming language.

• A robot’s behavior is changed by changing the programming blocks, which are called commands.

An electromagnet is a specific type of magnet where the magnetic field is produced by an electric current. The VEX VR Robot has an electromagnet to pick up and put down disks that contain metal cores.

ELECTROMAGNET

An electromagnet is a type of magnet where a magnetic field is produced by an electric current. The VEX VR Robot has an Electromagnet to pick up and put down disks that contain metal cores.

Disks with metal cores can be found on specific VR Playgrounds, and can be used with the Electromagnet on the VR Robot

Day-2

• The Distance Sensor reports the distance between the front of the Distance Sensor on the VR Robot and the nearest object. 

• The Distance Sensor is located in the Front Eye on the VR Robot.

• The Distance Sensor calculates distance by using the time it takes for ultrasonic waves to bounce off of an object and return to the sensor.

Where is the distance sensor located?

<Distance found object> block

• The Distance Sensor detects if there is an object in front of it when the <Distance found object> block is used in a project.

• <Distance found object> reports TRUE when the Distance Sensor detects an object or surface within its field of view, and within 3000 mm of the sensor. Otherwise FALSE.

How to use the distance sensor in the project?

(Distance from) block

• The (Distance from) block is a numeric reporter block that reports the distance of the nearest object from the front of a VR Robot.

What is the use of a distance sensor

• The Distance Sensor can be used to avoid or find a wall or object. 

• Using the Distance Sensor will allow a VR Robot to drive up to an object without touching it. This can be helpful in navigating a maze without continuously bumping into the walls, to avoid an object, or to drive to an object or wall in the VEXcode VR Playgrounds.
