General Tips
The following video shows how to model a 3-axis Cartesian robot (H-bot). Robot arms can be mounted on external axes to extend their reach.
Follow these steps to set up your 3D model in RoboDK:
1.Drag and drop the 3D model (such as a STEP or IGES file) in RoboDK to load it into your station.
2.Open the mechanism builder: selectUtilities➔Model Mechanism or Robot.
3.UnderRobot Type, select3-linear axis (H-bot).
Follow these steps to create your Base Frame:
4.Once your object is split into different pieces, re-open the rail builder (selectUtilities➔Model Mechanism or Robot➔3-linear axis).
5.Rename your robot underRobot Name.
6.Create a reference frame at the 0 position of the rail. You can rename it asFrame Base.
Follow these steps to modify the position of the frame:
7.Open the frame panel bydouble clicking “Frame Base”.
8.Open the measurement tool:Tools➔Measurement.
9.Select the icon that is highlighted belowin the measurement tool and thenselect both edges of your objectto find the distance between both center points.
10.SelectCreate Geometryto create a line between both center points.
11.Now that the line between both points is created, you can selectClear Selection.
12.Select the center of the lineto find the measurement of the center point of your newly created line.
13.Copy the values and paste them as the frame position (as shown in the image below) to make sure that the frame position matches with the reference image.
Follow these steps to make sure that the orientations are the same:
14.Rotate90 degreescounterclockwise.
15.SelectFrame Baseand thenselect the rail 3D models(select each section one by one) as shown in the image below.
16.Enter the length of each rail in the measurement section.
17.Move each axis underJoint Axis Jogto make sure each axis is moving fine.
18.PressUpdateafter testing each axis to create your robot.
19.If you are fine with the results, you canpress Okon the model mechanism window.
