介绍#
The VEX AIM Coding Robot uses a holonomic drivetrain to move forward, reverse, left, right, or at an angle while also being able to turn independently. Motion blocks control how the robot moves and turns, how fast it moves, and how its x and y position are tracked.

The move with controller stack block lets you drive the robot using the One Stick Controller. This block only reads the controller input once, unless placed inside of a loop, such as a forever loop. If the loop stops and there are no other blocks telling the robot to move, the robot will keep going in the last direction you pushed the joystick.

设置移动速度#
The set move velocity stack block tells the robot how fast to move. A higher percentage makes the robot move faster and a lower percentage makes the robot move slower.
Every project begins with the robot moving at 50% velocity by default.
A move velocity of 100% is equivalent to 200 millimeters per second (mmps).
set move velocity to (50)%

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.
A turn velocity of 100% is equivalent to 150 degrees per second \(dps\).

位置#
位置#
The position reporter block reports the robot’s current x or y-coordinate.
At the beginning of a project, the robot’s x and y positions are set to 0. The position values change as the robot moves and can be set using the set robot position block.

设置机器人位置#
The set robot position stack block changes the robot’s current x and y position to new values.
For example, if the robot has moved away from its starting point, setting x to 0 and y to 0 makes the robot’s current location the new 0, 0 position. Then the robot can track future positions based on that new value.
