# Coordinate control

Coordinate control is to make the robot arm move to a specified point with a specified posture, which is divided into x, y, z, rx, ry, rz. X, Y and Z represents the position of the robot arm head in space (The coordinate system is Cartesian coordinate system); [rx,ry,rz] represents the posture of such head at this point (The coordinate system is Euler coordinates).

## 1 Single parameter control

### 1.1 Sending single parameter coordinates

WriteCoord(Axis axis, double value, int speed = DefaultSpeed)
Return value: no
parameter description: Parameter 1: coordinate number (Axis enumeration type, int: 1-6 (X-RZ)); Parameter 2: coordinate (X, Y and Z range from -300 to 300.00 in mm; RX, RY, RZ ranges from -180 to 180); Parameter 3: speed (0-100), the example with 30 as a default
example:

``````mycobot::MyCobot::I().WriteCoord(mycobot::Axis::X, 10, 30);
``````

## 2 Multi-parameter control

### 2.1 Get all coordinates

GetCoords() Return value: Coords type parameter description: no example: mycobot::Coords coords = mycobot::MyCobot::I().GetCoords();

### 2.2 Send all coordinates

WriteCoords(const Coords& coords, int speed = DefaultSpeed)
Return value: no
parameter description: Parameter 1: coordinates ( X, Y and Z range from -300 to 300.00 in mm; RX, RY and RZ range from -180 to 180); Parameter 2: speed (0-100), the example with 30 as a default
example:

``````mycobot::Coords goal_coords = {5, 5, 5, 5, 5, 5 };
mycobot::MyCobot::I().WriteCoords(goal_coords, 30);
mycobot::Coords goal_coords = {5, 5, 5, 5, 5, 5 };
mycobot::MyCobot::I().WriteCoords(goal_coords, 30);
``````
