Robot Specific Blocks#

Looks #

Robot Looks #

Glow #

The Glow block is used to set the glow color of the indicator light in the center of the 123 Robot.

This is a non-waiting block and allows any subsequent blocks to execute without delay.

Monitor Looks #

The virtual 123 Robot also has access to all standard VR Looks blocks. Go here to access documentation for the VEXcode VR Looks blocks.

Sound #

Play sound #

The Play sound block is used to play the sound effect that is selected.

This is a non-waiting block and allows any subsequent blocks to execute without delay.

Play sound block for the 123 Robot, used to select and play sound effects without waiting other actions.

Select which sound effect to play.

Actions #

Act #

The Act block is used to act sad, happy, or crazy by having the 123 Robot perform a sequence of drive, turn, and sound behaviors.

This is a non-waiting block and allows any subsequent blocks to execute without delay.

Select which emotion to perform.

Sad: The 123 Robot will drive in reverse, turn left, then right, play an ‘uh oh’ sound, and then will drive forward to mimic a sad behavior.
Happy: The 123 Robot will turn right 360 degrees and play a laughing sound to mimic a happy behavior.
Crazy: The 123 Robot will turn left in a circle, and then turn right in a circle, all while playing a ‘loopy’ sound to mimic a crazy behavior.

Sensing #

The virtual 123 Robot has access to the standard Brain and Drivetrain Sensing blocks.

Eye Sensing #

Found object #

The Found object block is used to report if the Front Eye Sensor detects an object within approximately 40 millimeters (mm) or 1.5 inches.

The Found object block reports True when the Front Eye Sensor detects an object within approximately 40 millimeters (mm) or 1.5 inches.

The Found object block reports False when an object is not within approximately 40 millimeters (mm) or 1.5 inches.

The Found object block is used in blocks with hexagonal (six-sided) spaces.

In this example, the robot will check if its Front Eye Sensor has detected an object and print if it has or hasn’t detected anything.

Detects color #

The Detects color block is used to report if the Front Eye Sensor detects the specified color of an object.

The Detects color block reports True when the Eye Sensor detects the specified color of an object.

The Detects color block reports False when the Eye Sensor does not detect the specified color of an object.

The Detects color block is used in blocks with hexagonal (six-sided) spaces.

In this example, the robot will check if its Front Eye Sensor has detected a Blue object and print if it has detected one.

Hue of #

The Hue of block is used to report the hue value of the color detected by the Eye Sensor.

The Hue of block provides a hue value between 0 to 359 degrees. This provides a more precise measurement of color.

The Hue of block is used in blocks with circular spaces.

In this example, the robot will print the current hue of an object. Since there is no object in front of the sensor, it will print a 0.

Eye detects bright object #

The Eye detects bright object block is used to report if the Eye Sensor senses a bright or dark value.

The Eye detects bright object block reports True when the Eye Sensor senses a brightness value greater than 70%.

The Eye detects bright object block reports False when the Eye Sensor senses a brightness less than or equal to 70%.

The Eye detects bright object block is used in blocks with hexagonal (six-sided) spaces.

In this example, the robot will only drive forward when there is a dark brightness value (below 70%) in front of it.

Brightness of #

The Brightness of block is used to report the brightness of the object detected by the Eye Sensor.

Gyro Sensing #

Detected crash?#

The Detected crash? block is used to report if the robot has come in contact with a wall or other object.

The Detected crash? block reports True if the robot comes in contact with a wall or other object.

The Detected crash? block reports False if the robot does NOT come in contact with a wall or other object.

The Detected crash? block is used in blocks with hexagonal (six-sided) spaces.

In this example, the robot will drive forward until it has crashed, then it will stop moving.
