A heading is the direction the robot is facing, measured in degrees. The turn to heading stack block turns the robot to face a specific heading from -359 to 359 degrees. The robot will turn the shortest direction to reach the target heading.

The starting heading is 0 degrees.

turn to rotation #

The turn to rotation stack block turns the robot to a specific rotation.

Rotation is how much the robot has turned, measured in degrees. At the beginning of a project, the rotation value is set to 0 degrees. Rotation can also be set using the set drive rotation block.

Rotation values are absolute. This means the direction of the turn depends on the robot’s current rotation. Turning right increases the rotation, and turning left decreases the rotation.

For example, if the robot starts at 0 degrees and you turn to a rotation of 720 degrees, it will turn right twice. If you then turn to a rotation of 360 degrees, it will turn left once, because 360 is less than 720.

The project will wait until the robot is done turning before the next block in the stack runs.

转向至 (90) 度 ▶

参数	描述
rotation	The rotation value, in degrees, that the robot will turn to. This can be an integer or a decimal.
and don’t wait	Select the arrow ( ▶ ) to expand the block to say and don’t wait, so the next block in the stack will run right away.

set drive velocity #

The set drive velocity stack block tells the robot how fast to drive. A higher percentage makes the robot drive faster and a lower percentage makes the robot drive slower.

Every project begins with the robot driving at 50% velocity by default.

Note: A higher velocity makes the robot drive faster, but it may be less precise. A lower velocity makes the robot drive slower, but it can be more precise.

设定驱动速度为 (50) [% v]

参数	描述
速度	The velocity to drive with from 0% to 100%.

The set turn velocity stack block tells the robot how fast to turn. A higher percentage makes the robot turn faster and a lower percentage makes the robot turn slower.

Every project begins with the robot turning at 50% velocity by default.

Note: A higher velocity makes the robot turn faster, but it may be less precise. A lower velocity makes the robot turn slower, but it can be more precise.

设定转向速度为 (50) [% v]

[右 v] 转 (100) 度 ▶
等待 (1) 秒

set drive heading #

A heading is the direction the robot is facing, measured in degrees. The set drive heading stack block changes the robot’s current heading to a new heading value.

For example, if the robot has turned to face right, setting the heading to 0 degrees makes that right-facing position the new 0 degrees. Then the robot can turn to other positions based on that new heading.

设定底盘归位至 (0) 度

参数	描述
heading	The heading value, in degrees, to set for the robot.

例子

当开始 :: hat events
[Turn to the left.]
设定底盘归位至 (90) 度
归位至 (0) 度 ▶

set drive rotation #

Rotation is how much the robot has turned, measured in degrees. At the beginning of a project, the rotation value is set to 0 degrees. The set drive rotation stack block changes the robot’s current rotation to a new value.

For example, if the robot has made two full turns to the right, its rotation value will be 720 degrees. Setting the rotation to 0 degrees will reset that rotation from 720 to 0 degrees. Then the robot can turn to rotations based on that new value.

设定底盘转向至 (0) 度

参数	描述
rotation	The rotation value, in degrees, to set for the robot. This can be an integer or a decimal.

例子

当开始 :: hat events
[Spin counterclockwise two times.]
设定底盘转向至 (720) 度
转向至 (0) 度 ▶

set drive timeout #

The set drive timeout stack block sets how many seconds the robot will try to finish a movement. If the robot cannot finish in that time it will stop trying and move on to the next block in the stack. This keeps the robot from getting stuck on a movement.

设定驱动超时为 (1) 秒

参数	描述
时间	The number of seconds the robot can try to finish a movement. This can be a whole number or a decimal.

例子

When started, limits drive time to 1 second and then turns 90 degrees.#

旋转电机定位 #

The spin motor to position stack block spins a motor to a specific position.

A motor’s position is how far it has spun, measured in degrees or turns. One turn is equal to 360 degrees. At the beginning of a project, the motor position is set to 0 degrees. The motor position can also be set using the set motor position block.

Position values are absolute. This means the direction of the spin depends on the motor’s current position.

For example, if the motor starts at 0 degrees and spins to a position of 720 degrees, it will spin forward two turns. If it then spins to a position of 360 degrees, it will spin reverse one turn, because 360 is less than 720.
