Many processes require switching between two constant process-synchronous speeds at a precise point. Since this leads to an often significant jump in speed, you previously tried to trap such jumps on appropriate drive parameter settings. But then the reversing point isn’t reached exactly anymore

In the video you can see very well how “hard” for example the turn is on the lower reversing point without appropriate drive parameter settings and the second upper reversing point is not reached exactly with pure drive parameter adjustments. But here we want to present a solution with which such a turning maneuver is simple to implement position setpoint based with polynomials (as you can see at the first upper reversing point where the mouse points to). The user has to define only the area in which to place the maneuver and specify the exact time at which the reversing point has to be reached.

A corresponding algorithm calculates a reversing polynomial (optional 5th or 7th degree), which can be integrated as a cam segment or as a table into the movement. In the picture above you can see how such a reversing polynomial can be programmed for example using JetSym STX. The calculation itself takes a maximum of one to two milliseconds even at a smaller Jetter controller.

Imagine, you would have to program a commercial robot to draw a two-dimensional heart. Probably in most cases the robots hand would be lead standing always vertically on the surface of the heart then.

The question whether this movement is ergonomic usually does not arise at first glance. But what if this would not only save energy, but simultaneously would also protect your robots mechanics? At least then you would let the robot optimize itself.

And the movements would even look more beautiful and elegant, almost like out of a master’s hand … Talk to us or request a free demo software. We look forward to your contact.

Our new software for modern Motion Design and Optimization allows at the interface between CAD ​​/ CAE systems, process simulation, motion controllers and drive sizing tools a uniform implementation of your overall mechatronic concept. Different approaches uniting Dr. Thomas Müller and SIMON Modellierungen developed the easy-to-handle Motion Design tool with 3D Viewer and Motion Optimization already on board.

In robotics you are able to optimize and simulate 3D paths with orientation including the complete robot model (masses and moments of inertia of load, robot arms, gears and motors). Paths can be created with optimization objectives such as minimum acceleration, reduced-power, energy-minimizing and last but not least minimum cycle time. This might result in minimal arm burdening, minimal wear and tear. Smooth handling can be achieved as well.

Even one or multidimensional CAMs can easily be created, optimized and visualized. This allows you to optimize your systems already in the design phase data-consistent from CAD to motion controllers.

Let us impress you by the diverse possibilities of our Motion Design Software arranging an appointment at your site. We are looking forward to it!
