hi........frnds..get stick 2 dis blog 4 latest robotic technology.....n.....mind tat robotics rockz!!!!

S1 Snake Robot Prototype

Materials: Basswood and brass.

Components: Discrete TTL Control Unit, 14 servos, 16 batteries, 2-channel radio control. S1 was a recreation of earlier work by Shigeo Hirose in Japan, in which a single train of deflection travels down the length of the snake. Oscillatory deflections cause the snake to move forward. An offset to the oscillations causes the snake to steer. The wheels on each segment allow the snake to slide along its length while gripping laterally. Novel features include the use of servos of different sizes along the length of the snake to give a more tapered appearance. This feature increases the realism and efficiency of the snake but means that each segment has to be custom designed. Remote control is achieved using a vertical joystick for speed, and a horizontal one for steering.

Snake Robot Prototype (2001-2005)

Materials: Expanded PVC plastic, steel rod, and plastic gears

S7 is an experimental prototype that is still under development. It was inspired by a Dr. Miller's encounter with a python. In particular it avoids using wheels to achieve locomotion by implementing a more advanced segment design. This allows for rectilinear locomotion. S7 is far more sophisticated electronically than previous snake robots in the series, including bidirectional packet-based radio and a variety of sensors.

S7 under construction with initial sensor suite including compass, sonar and pyroelectric heat detectors

S7 final sensor suite including compass, pyroelectric heat and active infrared range sensors

c the sensors.....d snake equipped wid.......these sensors r mainly used by d bot 2 enter a closed obscure hole n can safely return back from it ........is'nt it rocks??
