“…Li et al used horizontally suspended weights to provide WOB when comparing the performance of full-wavelength and half-wavelength ultrasonic drill [28]; a linear actuator was used to provide WOB in ultrasonic-assisted drilling with active control [29]. Bai et al used horizontally suspended weights to provide drilling force for ultrasonic drill [30]. Wang et al used a combination of motor drive and buffer spring to provide the WOB, which has a similar effect to the scheme of horizontally suspended weights [31].…”

Multiple ultrasonic percussive drill cross-drilling anchoring helps to achieve long-term, secure attachment of sampling platforms in extreme environments. Ultrasonic percussive drills require less weight-on-bit (WOB) and lower power than conventional drills, making them more suitable for asteroid anchoring mission. Choosing a suitable WOB control method is one of the key factors to ensure rapid and stable drilling, but there is little research on the effect of WOB control method on ultrasonic drilling performance. To address the technical challenges of drilling, this paper investigates the effects of passive and active WOB control on ultrasonic drilling performance. Firstly, the mechanical configuration of an ultrasonic percussive drill is presented and a full-wavelength piezoelectric transducer is designed using impedance analysis (IA) and Experimental Modal Analysis (EMA). Then, passive control of WOB is implemented using suspended weights, and active control is implemented using a linear actuator. Finally, the effect of the WOB control method on drilling performance is experimentally verified on rocks with different compressive strengths. Our results show that active control is better suited to WOB variation and rock compressive strength variation. When the WOB is 5 N, the drilling rate of passive control is slightly higher than that of active control, but the difference is not significant. When the WOB is 10 N and 15 N, the drilling rate of active control surpasses that of passive control. The ultrasonic percussive drill's power consumption is less than 60 W. This paper provides a technical reference for selecting the WOB method for ultrasonic percussive drills in planetary exploration.

“…The inchworm drive motors are modeled by the unique crawling principle of the insect inchworm, and are driven by the alternating mode of "Clamping-Drive-Clamping", which has a large driving force and a large stroke, but they also have a large volume, complex structure, and slow movement speed [1][2]. Ultrasonic drive motors are driven by elliptical friction under the action of applied ultrasonic voltage, with fast speed and self-locking characteristics of power failure, but they have high requirements for the drive signal and serious heating problems caused by friction and wear [3][4]. The stick-slip drive motors adopt an asymmetric drive wave (sawtooth wave signal), and utilize the difference between the maximum static friction and sliding friction to drive by inertia, with a simple principle of motion, compact structure, and a motion speed between the inchworm motors and ultrasonic motors [5][6][7][8].…”

In the article, the design of a piezoelectric stick-slip rotary motor is proposed that can be used as the rotary drive part of a micro-nano operation. First, a force-coupled stator based on a flexible mechanism with a diameter of 23 mm was designed. Based on the designed stator, the structure of the rotary motor is constructed and its motion steps are analyzed. Then, finite element analysis is performed. Finally, the performance of the motor is tested and conclusions are drawn. The simulation and experimental results show that the developed motor performs well.
