Introduction: �Space mouse is developed by the DLR institute of robotics and mechatronics. �DLR- Deutsches Zenturum far Luft-und Raumfahrt. �First prototype applications of DLR control was showed from 1982 -1985. �The high sales price of about $8, 000 per unit
Principle: • The basic principle behind its construction is mechatronics engineering and the multisensory concept. • Measuring system is drift-free and not subject to aging effects. • Movements were measured by electromagnetic or ultrasonic. • 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 PSD.
SPACE MOUSE: • Space Mouse is a professional 3 D controller manipulating objects in a 3 D environment. • It has different modes of operation in which it can also be used as a two-dimensional mouse. • Groundbreaking interface. • Enables the user to intuitively zoom, pan and rotate models.
TYPES: Two types of space mouse • Space mouse classic • Space mouse plus
Specifications: PRODUCT Space Mouse Classic Space Mouse Plus SENSITIVITY adjustable BUTTONS 9, programmable 11, plus Quick tip programmable INTERFACE RS-232 C or USB CONNECTOR D-sub 9 pin or USB WEIGHT Weight 1. 46 lb (0. 66 kg) 1. 5 lb (0. 68 kg) DIMENSIONS (Lx. Wx. H) 6. 50" x 4. 41" x 1. 57" (165 x 112 x 40 mm) 7. 40" x 4. 72" x 1. 73" (188 x 120 x 44 mm) WARRANTY 36 Months
Features: �Ease of use of manipulating objects in 3 D applications. �Calibration free sensor technology for high precision and unique reliability. �Nine programmable buttons to customize users preference for motion control. �Fingertip operation for maximum precision and performance. �Adjust sensitivity and motion control to the users preference. �Small form factor frees up the desk space. �Natural hand position (resting on table) eliminates fatigue.

Visual space mouse: • Visual space mouse can be divided into two main parts ØRobot control ØImage processing
Applications: • Works in graphical applications. • Object manipulation in 3 D applications.
Advantages: • Drawing times is reduced by 20%-30%. • Works without an additional power supply. • Adapted for a wide range of tasks including Ø mechanical design, Ø real time video animation and Ø visual simulation.
Future scope: • ROTEX is the only well known virtual environment. • Machine instruction allowance. • To develop virtual environment using space mouse.
Conclusion: we believe there is no other man - machine interface technology comparable to Magellan in its simplicity and yet high precision. It is used for 3 D manipulations in 6 doff, but at the same time may function as a conventional 2 D mouse.
