Space Mouse
[attachment=68232]
INTRODUCTION
Every day of your computing life, you reach out for the mouse whenever you
want to move the cursor or activate something. The mouse senses your motion and
your clicks and sends them to the computer so it can respond appropriately. An
ordinary mouse detects motion in the X and Y plane and acts as a two dimensional
controller. It is not well suited for people to use in a 3D graphics environment. Space
Mouse is a professional 3D controller specifically designed for manipulating objects
in a 3D environment. It permits the simultaneous control of all six degrees of
freedom - translation rotation or a combination. . The device serves as an intuitive
man-machine interface
The predecessor of the spacemouse was the DLR controller ball.
Spacemouse has its origins in the late seventies when the DLR (German Aerospace
Research Establishment) started research in its robotics and system dynamics
division on devices with six degrees of freedom (6 dof) for controlling robot grippers
in Cartesian space. The basic principle behind its construction is mechatronics
engineering and the multisensory concept. The spacemouse has different modes of
operation in which it can also be used as a two-dimensional mouse.
Inside a Mouse
The main goal of any mouse is to translate the motion of your hand into signals that
the computer can use. Almost all mice today do the translation using five
components:
1 What is Mechatronics engineering?
Mechatronics is concerned with the design automation and operational
performance of electromechanical systems. Mechatronics engineering is nothing
new; it is simply the applications of latest techniques in precision mechanical
engineering, electronic and computer control, computing systems and sensor and
actuator technology to design improved products and processes.
The basic idea of Mechatronics engineering is to apply innovative controls to
extract new level of performance from a mechanical device. It means using modem
cost effective technology to improve product and process performance, adaptability
and flexibility.
FUTURE SCOPE AND CONCLUSION
DLR control ball, Magellan's predecessor
At the end of the seventies, the DLR (German Aerospace Research
Establishment) institute for robotics and system dynamics started research on devices
for the 6-dof control of robot grippers .in Cartesian space. After lengthy experiments
it turned out around 1981 that integrating a six axis force torque sensor (3 force, 3
torque components) into a plastic hollow ball was the optimal solution. Such a ball
registered the linear and rotational displacements as generated by the forces/ torques
of a human hand, which were then computationally transformed into translational /
rotational motion speeds.
The first force torque sensor used was based upon strain gauge technology,
integrated into a plastic hollow ball. DLR had the basic concept centre of a hollow
ball handle approximately coinciding with the measuring centre of an integrated 6
dof force / torque sensor patented in Europe and US
FUTURE SCOPE AND CONCLUSION
6.1 FUTURE SCOPE
Magellan's predecessor, DLR's control ball, was a key element of the first real
robot inspace, ROTEX- (3), which was launched in April 93 with space shuttle
COLUMBIA inside a rack of the spacelab-D2. The robot was directly teleoperated
by the astronauts using the control ball, the same way remotely controlled from
ground (on-line and off line) implying "predictive" stereographics. As an example,
the ground operator with one of the two balls or Magellans steered the robot's gripper
