How snakes moves in a straight line

Scientists have finally found the science behind the snakes straight line motion.University of Cincinnati biologist Bruce Jayne studied the mechanics of snake movement and explained how the snakes are propogate in a straight line.

Snakes can swim, climb or crawl by bending their spine into serpentine coils. They normally moved by  using their leading edges to push off objects.

Types of snake Movements

Types of snake movement
  1. Serpentine
  2. Concertina
  3. Sidewinding
  4. Rectilinear

Serpentine: Also called lateral undulation, this is the typical side-to-side motion used by snakes over rough ground or in the water.

Concertina: Snakes coil into alternating curves before straightening themselves to propel themselves forward.

Sidewinding: Snakes bend in waves both side to side and in a vertical plane to lift the body to form just a few contact points with the ground. This helps rattlesnakes traverse hot sand or climb dunes.

Rectilinear: Specialized muscles move the belly skin of a snake, propelling it forward in a straight line. This allows snakes to slip through burrows not much bigger than they are.

Researchers have tried to mimic the limbless, serpentine movements of snakes in robots. By using this movement in robots we can inspect pipelines and other underwater equipment

“This research could inform robotics. It would be a big advantage to be able to move in straight lines in small, confined spaces. They could use snake-like robots for search-and-rescue in debris and collapsed buildings,” Newman,the researcher added.
