Abstract
The aspects of the disclosed embodiments relate to a micromanipulator arrangement that includes at least one drive stem, at least one movable element arranged on the drive stem to move along the drive stem wherein the drive stem being arranged to cause a change in a position of the movable element with respect to the drive stem; wherein an additional factor exists having an effect in the change of the position of the movable element and the micromanipulator arrangement further comprises means for compensating said additional factor such that said effect is diminished.
Claims21
A micromanipulator arrangement;
- comprising
- at least two drive stems arranged in a parallel manner,
- a movable element arranged on the drive stems to move along the drive stems,
- the drive stems being arranged to cause a change in a position of the movable element with respect to the drive stem;
- wherein an additional factor exists having an effect in the change of the position of the movable element and the micromanipulator arrangement further comprises means for compensating said additional factor such that said effect is diminished.
A method for controlling a micromanipulator arrangement comprising at least two drive stems arranged in a parallel manner, and a movable element arranged on the drive stems to move along the drive stems, the drive stems being arranged to cause a change in a position of the movable element with respect to the drive stem, said method comprising:
- setting a reference position for a movable element of the micromanipulator arrangement,
- detecting actual position of said movable element,
- determining an effect of an additional factor having an effect in the change of the position of the movable element based on a difference between said reference position and said actual position
- compensating at least partly said effect of said additional factor in the micromanipulator arrangement using a compensation controller unit.
Use of a constant-force-generating part such as a constant-force spring to compensate for an effect caused by gravity in a micromanipulator arrangement, where said micromanipulator arrangement comprises at least two drive stems arranged in a parallel manner, and a movable element arranged on the drive stems to move along the drive stems, the drive stems being arranged to cause a change in a position of the movable element with respect to the drive stem.
A wireless micromanipulator, said micromanipulator comprising at least two drive stems arranged in a parallel manner, and a movable element arranged on the drive stems to move along the drive stems, the drive stems being arranged to cause a change in a position of the movable element with respect to the drive stem, wherein an additional factor exists having an effect in the change of the position of the movable element and the micromanipulator further comprises a force-generating unit for compensating said additional factor such that said effect is diminished.
