flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...

Here we present the control, performance and modeling of an untethered electromagnetically actuated magnetic micro-robot. The microrobot, which is composed of neodymium–iron–boron with dimensions 250 m 130 m 10 m, is actuated by a system of six macroscale electromagnets. Periodically varying magnetic fields are used to impose magnetic torques, which induce stick–slip motion in the micro-robot. ...

This work presents the dynamic modeling of an untethered electromagnetically actuated magnetic micro-robot, and compares computer simulations to experimental results. The micro-robot, which is composed of neodymium-iron-boron with dimensions 250 μm x 130 μm x 100 μm, is actuated by a system of 5 macro-scale electromagnets. Periodic magnetic fields are created using two different control methods...

This paper presents analytical and experimental results on a new hybrid tele-manipulation environment for micro-robot control under nonholonomic constraints. This environment is comprised of a haptic telemanipulation subsystem (macro-scale motion), and a visual servoing subsystem, (micro-scale motion) under the microscope. The first subsystem includes a 5-dof (degrees of freedom) force feedback...

In this paper, a worm-like micro robot designed for inpipe application with intelligent active force control (AFC) capability is modelled and simulated. The motion of the micro robot is based on an impact drive mechanism (IDM) that is actuated using piezoelectric device. The trajectory tracking performance of the modelled micro robot is initially experimented via a conventional proportionalinte...

In this paper, we presented the 4.0, 2.7, 2.5 mm, width, length, height size biomimetics micro robot system which was inspired by insects. The micro robot system was made from silicon wafer fabricated by micro electro mechanical systems (MEMS) technology. The mechanical system of the robot was equipped with small size rotary type actuators, link mechanisms and six legs to realize the ins...

This paper describes insect type micro robots controlled by a CMOS IC of hardware neural networks. The micro robot is fabricated by the micro electro mechanical systems (MEMS) technology using a silicon wafer, and the actuator is composed of artificial muscle wires on the basis of shape memory alloy. Insect-like walking is achieved by link mechanisms that transform the actuator’s rotational mot...

Mechanical testing of materials at the microscales is challenging. It requires delicate procedures not only for producing and handling the specimen to be tested, but also for applying an accurate and controlled force. This endeavor is even more challenging when it comes to investigating the behavior of brittle materials such as glass. Here, we present a microtensile tester for investigating sil...
