Robots already help people in many ways. Especially when there are many monotonous actions, which must be completed without mistakes, such as working on a production line. In harsh conditions, which are harmful for human, robots do their job perfectly. However, there are areas, which are out of bounds now, for example large water areas. You will need many measuring elements to keep track on temperature in all points of water surface. What if we go back to nature, and search solutions there?Water Strider robot is as good as his living counterpart - it is able to move across water using surface tension, which gives the uppermost areas of the liquid a bit of elasticity. It is very light, and with help of thin "legs", it stays on water. This will be extremely useful in works such as controlling temperature or quality of water in large areas, or in very small areas like sewer system. Imagine how it will lower cost of equipment when a couple of these nano-machines replace all measuring devices in a lake. In addition, taking in consideration that it is unrecognizable from its nature counterpart, it can be used in investigation as a spy device, fitting a small camera on its top will make this Water Strider Robot a perfect tool for covert operations.
It is early to think about the price now, because there is only one Water Strider Robot now, but if it proves its usefulness, it can be mass-produced in no time.
