Some robots do NOT need wheels, arms and legs for mobility, including off-board battery and no mechanism inside to generate locomotion, fish-like swimming does NOT work in BLOOD, Milli-/ Micro-/ Nano-scale robots are huge different to Macro-scale robots, let imagine how amazing super-soft robot walks in STOMACH, or swims in CSF to access BRAIN, MILLIONS of robots can be controlled once to save life from disease. etc.
All above is what we have done here
It is multidisciplinary research between Engineering, Biology, Sciences, Pharmacy and Medicines. It would be a new experience you have never realized its existence. We, here, do develop SMALLs for BIGs.
Our research still opens for all scale robots with the purpose to empower the world with robotics
We are looking for interested persons, who are willing to pursue graduate degree in Multiscale robotics research, here
