How they Work

These Nano Bots have an electromagnetic ring around them which helps them to join together horizontally as well as vertically ,but their acceptors help them join only vertically.
These Nanobots can also generate electricity on their own ,since they have their own photon panel i.e they can be used as an inverter which can power up household appliances.
Since they have their own Photon Panel , they don't require any extra power but convert light energy to electricity to power themselves.

The video below shows how the nanobots join together to make a humanoid figure.
