Fleas in nature generally have potent muscles for jumping and crawling abilities to overcome obstacles in complex environments, while it is challenging for flea-sized robots to have powerful actuators due to the size effect. This work presents a novel high-voltage pulsed actuator for a flea-sized ro
It is a significant challenge for microrobots to achieve fast crawling speed at the millimeter scale due to the limitation of actuator size effects. In this letter, we have designed a millimeter-scale microrobot configuration based on a new electric pulse drive principle. The microrobot has a high r
Insects and animals in nature generally have various modes of locomotion to adapt to complex environments, such as crawling, running, flying, and jumping. Achieving multi-locomotion in a centimeter-scale robot requires complex structures and mechanisms that are normally difficult to design and fabri
Several microrobots driven by capacitive actuators have shown excellent performance because of the high power density and low working current of the actuators. However, these capacitive actuators need high alternating working voltage (hundreds or thousands of volts), which results in heavy and bulky
This work presents a low voltage (5 V) control method for micro-ionic thrusters with high operating voltage (>1 kV). When the collector of a micro-ionic thruster is connected to the negative electrode through a 5V switch circuit, and a high DC voltage (1-10 kV) is applied to the emitter, we can get
