Drive functions
A rotating motion becomes an oscillating motion. You shape the motion profile directly in the diagram, segment by segment.

Excavator arm with three linear drives
An excavator arm with three linear drives: the example shows how you coordinate several drives in ASOMmini and track the path of the bucket.

The task
Three drives, one bucket movement
The excavator arm is built as a planar mechanism and has three degrees of freedom. Three linear drives move the boom, stick and bucket – one per degree of freedom. For the bucket to move as realistically as possible, the three movements have to be coordinated with one another.
What ASOMmini shows here
- ASOMmini displays the degree of freedom of the model – three in this case, so three drives.
- Each linear drive has its own drive function made up of segments such as a 5th-degree polynomial, constant velocity or sinusoidal acceleration; you see displacement, velocity and acceleration over time.
- Trajectories show the path the bucket follows.
Your benefits
Coordinate multiple drives
You immediately see how a change to one drive alters the entire motion sequence – already at the conceptual design stage.
Coordinated motion
You see early on whether the three drives together produce the desired bucket path. More on modeling and motion
Profiles without programming
You shape motion profiles in the diagram instead of in program code.
Bearing forces as well
Optionally, ASOMmini shows the joint and bearing forces, as vectors on the model and as a diagram. More on force calculation
