By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Researchers detail new data in Robotic s-Field Robotics. According to news reporting from Shenyang, People's Republic of China, by NewsRx journalists, research stated, "The low-velocity penetrator (LVP) is a planetary penetration device that can drive itself to a target depth through its internal periodic impacts. When LVP generates impact energy, it inev itably produces a recoil that can only be counteracted by friction with the soil , if there is no other auxiliary device." Funders for this research include National Key R&D Program of China , National Natural Science Foundation of China (NSFC), CAS Interdisciplinary Inn ovation Team. The news correspondents obtained a quote from the research from the Chinese Acad emy of Sciences, "Unfortunately, LVP is extraordinarily sensitive to the recoil during the initial stage since the small contact area with the soil results in m inor friction between them. Significantly, once the recoil exceeds the friction, LVP cannot work properly and may even retreat, inducing mission failure. In thi s paper, we develop an optimized LVP with an auxiliary device for lower recoil a nd higher performance. Specifically, we establish a dynamic model to analyze the single-cycle motion of LVP and provide essential support for its optimization a nd design. Meanwhile, an integration method is proposed to calculate the frictio n between LVP and the soil reasonably and accurately. On the basis of these, we obtain the optimal mass and stiffness parameters of LVP that meet both high pene tration efficiency and low recoil. Furthermore, only relying on the parameter op timization is insufficient to eliminate the recoil, and an auxiliary penetration scheme is proposed to provide an external force counteracting the recoil until LVP arrives at a certain depth. Through multiple comparative penetration experim ents, we validate the effectiveness of our approaches in promoting penetration a bility, stability, and restraining the recoil of LVP."
