Coordinate conversion criteria for KUKA robots

Create Date: 2024-8-30 12:03:23|Source: KUKA

Those who have used KUKA robots should know that to indicate the orientation of a robot's Cartesian coordinate system, FRAME/POS/E3POS/E6POS data will be used, where:

-X/Y/Z: indicates the rectilinear coordinates of the Cartesian coordinate system;

-A/B/C: indicates the Cartesian coordinate system rotation coordinates;

-S/T : indicates the condition and angle of the robot;

-E1.. E6: Indicates the viewpoint of the outer axis;

The Euler angle Euler-A-B-C of Kuka corresponds to Z->Y->X;

Two. Euler Angle Description:

Guidelines for the KUKA Robot Coordinate Conversion:

- One-step: X/Y/Z transformation (sequential independent);

- Step 2: A/B/C transformation (first A, then B, *** then C);

Three. A few operators:

The few operators allow you to add directions in a few ways. The addition of a few bits is also known as the "frame operation". In KRL, a colon ":" indicates a few operators.

1. Applicable data type: FRAME/POS/E6POS type data;

2. The operation of two operands:

3. The operation of three operands:

Four. Application Scenarios:

1. The robot moves 100mm in the east-west Z direction according to the current orientation:

- Traditional: LIN_REL {Z 100} #TOOL

- A few operators:

2. The robot moves 100mm along the Z direction of the base according to the current orientation:

- Traditional: LIN_REL {Z 100} #BASE

- A few operators:

Note: Relative motion commands are not recommended;

3. The vision camera informs the robot that it should be offset by -0.5 in the X direction of the base, 1.1 in the Y direction, and 0.2 in the A direction.

This is done with a few operators:

Five. Expansion (Offset Function)

1. Offset of the accounting point relative to the base coordinate CS:

2. The accounting point is offset from the east-west CS:
