Vectioneer Motion System Design Software

Motion System Design Software

Here are some more details on our motion system design software. Vectioneer presented the current status at last week’s Blender Conference.

Below you can see a screencast of the use of our new Motion System Design software. Our in-house developed simulation software is extended with a Blender frontend for easy user interaction.
With the software it is possible to intuitively design any parallel mechanism. The software calculates important system metrics on the fly, so it becomes very easy for the designer to optimize the design.

The video shows how the parameters of a Hexapod System, such as joint locations and payload center of gravity location, are changed to arrive at an asymmetric Hexapod design. At the end a detailed report is generated describing the system design and the requirements for all subsystems such as gearboxes, servomotors, joints, worst case forces.

The video below shows an animation of 3DOF motion system design, where the system is put in a certain pose when the brakes on the actuators are released and the system freefalls to a steady state. All system dynamics are modelled including payload and drive system inertias and coulomb friction.

Sneak peek: our in-house developed Motion System Design Software

Vectioneer has developed a revolutionary intuitive design tool to design parallel mechanisms such as Hexapod or Crank Driven Motion Systems. The algorithms that provide the kinematic and dynamic modeling are written completely from scratch and are implemented in Python 3. The software allows to change designs very quickly and calculate system performance and component specifications on the fly. This way it is possible to show the effect of design changes in real-time.

Using this dedicated software the design process is much more efficient than using regular CAD packages to model and simulate the system in. We can provide our customers with a new motion design in mere hours, including a complete report of all the kinematic and dynamic requirements on the system components, such as maximum servo motor torques and velocities, average power consumption, worst case forces, maximum joint angles, motion enveloppe drawings, etc.

Although largely complete, the software is still under heavy development to add more features such as genetic algorithms to search for optimal mechanism solutions automatically.

For the user interface we use our favorite free software, Blender, which turned out to be perfect for the job. It provides a fast and stable platform and has an excellent interface to our own Python code. As an extra it can render amazingly realistic pictures and animations of our designs to impress our customers with.

The software is not for sale, but is used to design new custom motion systems for our customers.

Motion System Tuning of the VTI Driving Simulator IV

Vectioneer was hired to perform motion system tuning of the VTI Driving Simulator IV in Gothenburg, Sweden. Sim IV is the latest of VTI’s driving simulators and one of the most advanced in the world. It features an exchangeable cabin design for truck or passenger car cabins, a large Motion System from Bosch Rexroth which can generate realistic motion cues to the driver, a nine channel visual system with a cylindrical screen, VTI’s in-house developed image generator, sound system with a subwoofer capable of simulating vibrations, vehicle dynamics models and traffic simulation. VTI developed the simulator in-house with its industry partners.

The simulator is used for research into vehicle systems, such as trucks or cars. Currently is setup for truck simulation and will be used to perform experiments with driver assistance systems.

Vectioneer was hired to tune the motion system of the simulator to maximum performance and perform the final acceptance testing with VTI. Also Vectioneer assisted VTI with the Motion Cueing algorithms and trained the VTI researchers in the use of Rexroth’s Motion Cueing software.

Here are some interesting links about the VTI Driving Sim IV, some of which are only available in Swedish (but the images and videos are worthwhile):
