Levitation has evolved into a top choice for a variety of tasks due to its contact-free nature and reduced danger of contamination. Beyond Earnshaw's theorem, magnetic levitation utilizing diamagnetism is a sort of energy-free passive stable levitation that is possible even at room temperature. Intriguingly, even materials that don't appear to be magnetic can be lifted in a magnetic field and used to stabilise the free levitate of magnetic materials. A simple approach of controlling complex magnetic fields using thermo-magnetic and optical material features is introduced. In a closed loop control system, the user can specify the positions of milli-robots that are automatically detected and actuated to the appropriate positions and work to maintain them there. In this paper we have used several diamagnetically levitated robots, which can show how to distribute dissolved bio-chemicals in liquid while still being able to view them under a light microscope. Fluorescent molecules are loaded into hydrogels with microscale precision and released in a diffusive manner, and synthetically created bacterial cells are activated with signalling molecules. This platform can be used in a wide range of fields, including synthetic biology, developmental biology, and tissue engineering.
