Repeatable precision simulated vibration
Image stabilisation in cameras that detect changes in position and any trembling motion of the photographer needs to have algorithms and/or a mechanical systems built into the camera to compensate for these unwanted movements and these compensations need testing for accuracy.
Simulation for test purposes requires natural and artificial motion to be precise and simulated repeatedly with the same levels of dynamics and accuracy. This involves running high-precision trajectories with the corresponding dynamics. Therefore, multi-axis, precise and dynamic positioning systems are absolutely essential.
Six-Axis Parallel Kinematics.
Thanks to their parallel kinematic design, there are a number of reasons why demands for Hexapods in test and calibration environments are increasing. They allow for precise and exact repeatable motion on all linear and rotatory axes.
Their advantages compared with serial, i.e. stacked systems, are that they have much better path accuracy, repeatability and flatness. In addition, the moved mass is lower, enabling better dynamic performance, which is the same for all motion axes.
Various Different Drive Technologies
Various different drive types are possible for highly dynamic simulation of predefined motion but Hexapods with electromagnetic, brushless torque motors and sensor technology can experience velocities of several hundred mm/s and accelerations of up to 4 g. With these capabilities motion simulation with high frequencies can be realized with high acceleration and at the same time follow precise specified trajectories.
