The coronavirus SARS-CoV-2 can survive in wastewater for several days with a potential risk of waterborne human transmission, hence posing challenges containing the virus and reducing its spread. Herein, we report on an active biohybrid microrobot system that offers highly efficient capture removal target from various aquatic media. algae-based is fabricated by using click chemistry to function...

This paper presents the analysis, design, and simulation of a novel microrobotic platform that is able to perform translational and rotational sliding with submicrometer positioning accuracy and develop velocities up to 1.5 mm/s. The platform actuation system is novel and based on centripetal forces generated by vibration micromotors. The motion principle is discussed in detail, and the dynamic...

Behavioral robustness at antibody and immune network levels is discussed. The robustness of the immune response that drives an autonomous mobile robot is examined with computational experiments in the trajectory generation context in unknown environments. The immune response is met based on the immune network metaphor for different low-level behaviors coordination. These behaviors are activated...

The work is motivated by problems during automated motion control of mobile microrobots. Microrobots are only cm-sized but can manipulate objects in the sub-micrometre-range. For a high positioning accuracy the microrobot’s actuator controller must be correspondingly accurate. But since a microrobot’s motion behaviour is difficult to model and since the model parameters even change with time, a...

A microfabricated normally-closed microvalve consisting of a flat silicon spring, a co-sputtered and patterned TitaniumNickel (TiNi) shape memory alloy (SMA) actuator, and an orifice die, is presented. All three components are batch microfabricated using silicon substrates. This microvalve is designed for an actuation mechanism for a pneumatically controlled, biologically inspired six-legged mi...

We present a novel method for independently controlling multiple stress-engineered MEMS microrobots (MicroStressBots) through a single, global, control signal. Called Turning-rate Selective Control (TSC), this new technique employs designed variations in turning rates between individual microrobots to differentiate their motion. Despite all robots moving simultaneously and being identical excep...

In the motion control of a microrobot swarm, a key issue is how to autonomously generate a set of common coordinates among all robots and how to notify each robot of its heading direction in the generated common coordinates without any special devices for estimating location and bearing. This paper proposes a set of common coordinates and a heading direction generation method for a robot swarm ...

We describe a new methodology and environment for Cyber Physical Systems (CPS) synthesis and demonstrate it in the design of microrobots viewed as CPS. Various types of microrobots have been developed in recent years for applications related to collaborative motion such as, sensor networks, exploration and search-rescue in hazardous environments and medical drug delivery. However, control algor...
