Excavator arm
Three linear drives, one per degree of freedom, move the boom, stick and bucket. Their motion profiles are coordinated with one another.

Shape drive functions in the diagram itself
A one-bar linkage should not rotate fully but move as a rocker. The example shows how to define the motion of the link for this in ASOMmini.

The task
From full rotation to rocker motion
A one-bar linkage consists of a single link that is mounted on the frame and driven. In the example, it initially rotates at a constant speed. However, it is supposed to move as a rocker. What matters is not only the angle but also how the link accelerates and decelerates.
What ASOM shows here
- You change the motion sequence directly on the graph for the drive angle – or on the angular velocity and angular acceleration.
- You divide the drive function into any number of segments, for example with constant velocity, sinusoidal acceleration or as a 5th-degree polynomial; you specify the transitions.
- The three diagrams are linked: every change is immediately reflected in all curves and in the motion of the link.
Your benefits
Define motion profiles in conceptual design
You see angle, velocity and acceleration side by side and define early on how a drive should move.
A profile without formulas
You shape the motion on the graph instead of calculating it by hand, segment by segment. More on modeling and motion
Smooth transitions
You fine-tune how the link accelerates and decelerates, not just its angle.
Find the right motion quickly
You try out profiles directly and immediately see which one fits.
