The field of small-scale wireless medical robotics is rapidly evolving, with a focus on developing innovative solutions for various medical applications. While the potential of microrobots to revolutionize healthcare remains significant, the current research emphasis has shifted toward addressing key challenges in their clinical translation. For the successful medical translation of small-scale wireless medical robots, we focus on these research questions:

• Actuation and Control: We are working on developing more efficient and precise methods for controlling microrobots in complex biological environments. This includes improving magnetic actuation techniques and exploring new forms of propulsion.
• Material Design and Fabrication: There is a strong emphasis on creating biocompatible and biodegradable materials for microrobots. Advanced fabrication techniques are being developed to produce microrobots with complex geometries and functionalities.
• Imaging and Tracking: Efforts are being made to enhance the visibility of microrobots using various imaging modalities, such as ultrasound, magnetic resonance imaging (MRI), and fluorescence imaging. This is crucial for real-time monitoring and control in clinical settings.
• Biological Interactions: Understanding and optimizing the interactions between microrobots and biological tissues is a key area of focus. This includes studying how microrobots navigate through different bodily fluids and tissues, as well as their potential immune responses.
• Drug Delivery and Therapeutic Applications: Researchers are developing microrobots capable of targeted drug delivery, with a focus on improving efficacy and reducing side effects. This includes designing microrobots that can respond to environmental cues for controlled release of therapeutic agents.
• Safety and Biocompatibility: Ensuring the safety of microrobots for in vivo use is a critical area of research. This involves studying long-term effects, developing retrieval strategies, and creating biodegradable microrobots.
