Peoples who are interested to see Different type of snakes will be really amazed to see a Robotic Snake. Hirose-Fukushima Lab at Tokyo Institute of Technology is doing R&D on an amphibious snake robot ACM-R5. They have made one, looks much similar to snake (real one) in movement but not in outlook; you can see him in action in the video at the end.
The robot moves same like real snake on the land and in the water. The main feature of the robot is its joints, which combine bellows with universal joints. The bellows prevent water from penetrating the universal joints.
The whole robot’s body is covered with wheels and paddles which allows it to gain a propulsive force helping in twisting the body, robot can slide easily in the direction tangential to the body, but not in the perpendicular direction. These wheels and paddles help this thing to achieve on land and in water also.
Every joint unit contains a CPU, Battery and Motor. Each unit exchanges signals independently, and automatically recognizes how far the head is and how many joints are there in the body. This makes quite possible to add and replace joints freely.
In real world scenario it doesn’t look much of a use, but with more R&D it can help a lot in some situations…
