  • Every day of our computing life, we reach out for the mouse whenever we want to move the cursor or activate something. The mouse senses our motion and our 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 interfaceSpaceMouse is a essential tool as our mouse or keyboard, giving us the ability to manipulate 3D objects on the screen, while simultaneously controlling 3D camera angles and positions for viewing those objects. It’s a much more natural, free-flowing way to work. If we use a common interface, executing even simple moves requires a decision, then keystrokes and/or mouse clicks. This interrupts our natural motion, slowing us down and actually restricting us from attempting more complete or continuous motion. But, the greater flexibility and interactivity of a 3D motion controller makes even difficult moves easy. With space mouse We are free to go farther and even more creative.
  • 1---The main goal of any mouse is to translate the motion of your hand into signals that the computer can use. General Computer mouse is subjected to only 2-D motion.2--Almost all mice today do the translation using five components: 1 A ball inside the mouse touches the desktop and rolls when the mouse moves. 2 Two rollers inside the mouse touch the ball 3 When roller rolls, its shaft and disk (with holes) rotates. 4an infrared LED and an infrared sensor notes the hole movement as pulses. 5 An on-board processor chip reads the pulses and turns them into binary data that the computer can understand.computer mousespace mouse2-dimesnsional movement. 3-D movement.Low precision high precisonNo adjustment for senstivity adjustment for sentivity and motion controlNo programmable button 9/11 programmable buttonV-shaped cap naturally supports the zoom feature
  • Inventor: DLR( established by german aerospace).thisinstitute for robotics and system dynamics started research on devices for the 6-dof(degree of freedom) control of robot grippers in Cartesian space. After lengthy experiments itintegrated a six axis force torque sensor in compact shape. The first force torque sensor used was based upon strain gauge technology, integrated into a plastic hollow ball. the first prototype applications showed that DLR's control ball was not only excellently suited as a control device for robots, but also for the first 3D-graphics systemBasic idea:The new system used 6 one-dimensional position detectors. The measuring system consists of an inner and an outer part. The measuring arrangement in the inner ring is composed of the LED, a slit and perpendicular to the slit on the opposite side of the ring a linear position sensitive detector (PSD). The slit / LED combination is mobile against the remaining system. Six such systems (rotated by 60 degrees each) are mounted in a plane, whereby the slits alternatively are vertical and parallel to the plane. The ring with PSD's is fixed inside the outer part and connected via springs with the LED-slit-basis. The springs bring the inner part back to a neutral position when no forces / torque are exerted:
  • 1 Mechatronics engineering is simply the applications of latest techniques in precision withmechanical engineering, electronic and computer engg., computing system, 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 electronic and mechanical device.Mechatronics came up having technical systems operating mechanically with respect to some kernel functions but with more or less electronics supporting the mechanical parts decisively. Mechatronics covers a wide range of application areas including consumer product design, instrumentation, manufacturing methods, computer integration and process and device control. Computer disk drives are one example of it. A typical Mechatronic system picks up signals processes them and generates forces and motion as an output. In effect mechanical systems are extended and integrated with sensors(to know where things are), microprocessors (to know what to do), and controllers (to perform the required actions).
  • Space mouse is the successive growth of DLR control ball - to magellan –then to space mouse.Purpose“:- toregister 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. Its development was caused only to fulfill the six axis force torque sensor in compact shape.Working:- it consists of two parts:1 inner ring 2: outer ring. The measuring instruments consists of LED, slits and linear position sensitive detector (PSD). The slit and LED combination is mobile against the remaining system.Six such systems (rotated by 60 degrees each) are mounted in a plane, whereby the slits alternatively are vertical and parallel to the plane. . The PSD have springs which bring the inner part back to a neutral position when no forces / torque are exerted. This measuring system is drift-free and not subject to aging effects. magellan:-DLR's development group redesigned the control ball idea with its unsurpassed opto electronic measuring system and optimize it thus that to reduce manufacturing costs.it was The wear resistant and drift free opto electronic, 6 component measuring system was optimized to place all the electronics, including the analogous signal processing.This new manipulation device was also able to function as a conventional mouse.Magellan was constructed as flat as can be so that the human hand may rest on it without fatigue. Slight pressures of the fingers on the cap of Magellan is sufficient for generating deflections in X, Y, and Z planes, thus shifting a cursor or flying a 3D graphics object translationally through space. Slight twists of the cap cause rotational motions of a 3D graphics object around the corresponding axes. Pulling the cap in the Z direction corresponds to zooming function. Moving the cap in X or Y direction drags the horizontally and vertically respectively on the screen. Twisting the cap over one of the main axes or any combination of them rotates the object over the corresponding axis on the screen.Space mouse:-With the integration of nine additional key buttonsThe device has special features like dominant mode. It uses those degrees of freedom in which the greatest magnitude is generated. So defined movements can be created. Use of handshake signals (RTSSCTS) ensures the safe operation of the spacemouse. Additional signal lines are provided to power the Magellan (DTS&RTS). Touching the keys results in either the usual menu selection, mode selection or the pickup of 3D objects.
  • 1----A three-dimensional computing environment could possibly be used for collaborative work. For example, study of three-dimensional models of molecules in a virtual reality environment, or assembling a three-dimensional model of an airplane. For such time of precised movement the spacemouse with 6 degree of freedom provides the greater reliablility, hence preferred for such 3-d motion.2---with “space mouse,’” teleporting the robots directly with precise movement over a distant place is convenient and error less so it is preferred to control the robots with such a sharply sensored device providing the virtual reality. The SPACE-MOUSE is the recent product based on these ideas. stiff strain-gauge based 6 component force-torque-sensor systems. miniaturized triangulation based laser range finders. integrated inductive joint-torque-sensor for light-weight-robot.
  • Use of handshake signals(RTSSCTS) are provides for the safe operation of space mouse.Settings to adjust senstivity and motion control to the user prefrence.Small form factor.Fingertip operation
  • 1--Magellan's predecessor, DLR's control ball, was a key element of the first real robot in space, 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. hence with space mouse teleoperating the robots over such a great distance with precise movement is possible.2--A most intuitive controlling device would be a system that can be instructed by watching and imitating the human user, using the hand as the major controlling element. This would be a very comfortable interface that allows the user to move a robot system in the most natural way.
