Tiny robot breaks the myth whoever believes that an only big thing comes in big package. This time Stanford University engineers successfully invent a tiny robot having amazing capacity and capability to carry 2,000 (approx) times heavier weight than itself. This research work will defiantly give new direction to the robotic area that have the space problem to working with big robots.

This tiny robot inspired by a gecko behavior and working style to carry very heavy weight than itself weight. The overall concepts to making tiny robot takes form gecko drag style with carry heavy weight. This miniature bot can pull heavy objects that are nearly two thousand (2,000) times than tiny robot itself.

The most impressive part of this miniature robot – which are aptly named MicroTugs – is that; its weights only twelve (12) grams and this 12 grams miniature bot capable of pulling heavy objects with weight upto two thousand (2,000) times than its own weight. One another miniature bot having nine (9) gram weight having capability to climb up a glass over a kilogram weight. Co-creator David Christensen says about this invention that it is the equivalent of a person dragging a blue whale and climbing up a skyscraper while lugging an elephant, respectively. In the experimental setup a twenty (20)-milligram bot able to climb up to five hundred (500)-milligrams weight paper clip.

Now the first question arises in the mind of every one, how can this be??

These tiny robots borrow the creep technology from inchworms and geckos as they are traverse in their terrain and borrow his food from one place to other. From the gecko technology researcher inspired and cover the feet of robot with tiny rubber spikes that bend when a pressure is applied on them and straighten out when the robot picks its foot back up. With this gecko traversing technique researchers merge another technique of inchworms, i.e. when inchworms creep on ground then on every step one half of its body moves forward, and the rest part of the body stays in place to fix the body without slip. This concept of half movement of body supports the tiny robot being pulled heavy weight and it allow this miniature bot to climb walls without slip of robot and losing its grip on carry weight as well.

Engineers review about this research is that, “This tiny robot work demonstrates that can apply orders of magnitude more force than its own weights”. This robot is in contrast to previous work related to small robots that have become progressively better at moving and sensing, but it lacked the ability to change the world through the application of human-scale loads”.

Application of tiny robot:

This miniature bot will very beneficial in many applications either in medical field, agriculture field and daily use in home works etc.

Suppose you want a catch a coffee cup and it’s not in your range then at that moment this tiny robot will helpful for you to brought heavy coffee cup for you . This tiny robot is not bounded here. Although the team of researcher hopes that this machine will gives an positive edge in the working strategy in factories, at construction sites, climb up heavy material through wall and even useful in emergency scenarios. This robot will be the best replacement of rope ladder in future for many different works like objects placements or helpful in burning buildings.

This robot will be presented in the next month at the International conference on Robotics and Automation in Seattle.
