SNAKEBOT
INTRODUCTION
• A snakebot is a biomorphic hyper-redundant
robot that resembles a snake.
• Snakebots are constructed by chaining
together a number of independent links
• Currently being used for Space ,Military and
Medical applications
MAIN FEATURES
• Small cross section to length ratio allows
them to move into tight spaces
• Ability to change the shape of their body
allows them to perform a wide range of
behaviours
NEED FOR SNAKEBOT
• Autonomy
• High mobility
• Robustness
• Modularity
FUNCTIONS
• Utilization of robotics technology for human
assistance in any phase of rescue operations
• Snakebots will slither and dig underneath the
soil for geological surveying
• Medical Snakebots can maneuver around
organs inside a human chest cavity
BASIC PROTOTYPES DEVELOPED
• Fire fighting snakebot developed by SINTEF
• Medical snakebot developed at Carnegie
Mellon University
• Space-Snakebots developed by NASA
• Rescue-Snakebots developed by US Army
Sensor

BASIC PARTS
• Central Computer
• Microcontrollers
• Motors
• Sensors
• Wheels/Conveyor Belts
• Gears
• Camera
• Connecting Rods
WORKING
• Central computer works in conjunction with
smaller computers in each module
• Microcontrollers interpret signals from the
main computer to control movement
• Sensors will indicate if the snake is in contact
with anything
• Motors move the various parts in each
module
• Wheels are responsible for transporting the
snakebot
• Gears allow movement of the hinges
• Camera for vision and recording images
• Connecting Rods will pull and activate the
section next to it
DIFFERENT TYPES OF MOVEMENT
• Move forward with rectilinear or lateral
motion.
• Move right/left with flapping motion.
• Change of direction
TYPES OF LOCOMOTION MODE
• Line mode
• Wheeled-locomotion mode
• Inching mode
• Ring mode
• Bridge mode
OTHER APPLICATIONS
• Bridge inspection
• Rescue operation under trench
• Spy purpose Operations
ADVANTAGES
• Small in size and weight
• Versatility
• Reliability
• Low expenses
DISADVANTAGES
• Hard to control
• Cannot optimize its own path
CONCLUSION
• Serpentine mechanisms, with their wide range
of capabilities, face major design challenge
mechanism design, path
planning, control, and sensor integration.
• The test versions of the snakebot have been
remote controlled. Eventually, scientists will
find ways to give these robots a form of
intelligence so that they can operate by its
own
