EVOLUTIONEVOLUTION

The predecessor of the space mouse was The predecessor of the space mouse was the DLR controller ball.the DLR controller ball.

Redesigned the control ball idea with its Redesigned the control ball idea with its unsurpassed optoelectronic measuring unsurpassed optoelectronic measuring system and optimized it to reduce system and optimized it to reduce manufacturing costs to a fraction of its manufacturing costs to a fraction of its previous amount and thus allow it to previous amount and thus allow it to approach the pricing level of high quality approach the pricing level of high quality PC mouse at least long-term.PC mouse at least long-term.

Spacemouse has its origins in the Spacemouse has its origins in the late seventies when the DLR late seventies when the DLR (German Aerospace Research (German Aerospace Research Establishment) started research in its Establishment) started research in its robotics and system dynamics robotics and system dynamics division on devices with six degrees division on devices with six degrees of freedom (6 dof) for controlling of freedom (6 dof) for controlling robot grippers in Cartesian space.robot grippers in Cartesian space.

FUTURE SCOPEFUTURE SCOPE

Magellan's predecessor, DLR's control ball, was Magellan's predecessor, DLR's control ball, was a key element of the first real robot in space, a key element of the first real robot in space, ROTEX- (3), which was launched in April 93. ROTEX- (3), which was launched in April 93.

A most intuitive controlling device would be a A most intuitive controlling device would be a system that can be instructed by watching and system that can be instructed by watching and imitating the human user, using the hand as imitating the human user, using the hand as the major controlling element. This would be a the major controlling element. This would be a very comfortable interface that allows the user very comfortable interface that allows the user to move a robot system in the most natural to move a robot system in the most natural way. This is called the way. This is called the visual space mousevisual space mouse..

CONCLUSIONCONCLUSION

The graphics simulation and manipulation of The graphics simulation and manipulation of 3D volume objects and virtual worlds and 3D volume objects and virtual worlds and their combination is not only meaningful for their combination is not only meaningful for space technology, but will strongly change space technology, but will strongly change the whole world of manufacturing and the whole world of manufacturing and construction technology . For all these construction technology . For all these applications we believe there is no other applications we believe there is no other man- machine interface technology man- machine interface technology comparable to Magellan in its simplicity and comparable to Magellan in its simplicity and yet high precision. yet high precision.
