A Visible and Near-Infrared Light-Fueled Omnidirectional Twist-Bend Crawling Robot

In recent years, although light-driven soft actuators have attracted intense scientific attention and achieved remarkable progress, the design and construction of an intelligent robotic system with maneuverability, self-adaptability, untethered control, and greater freedom of action, in particular the omnidirectional motion capability on a plane, remains challenging. Herein, four types of photo-thermal fillers and an unprecedented twist-bend actuation mode is introduced into a liquid crystal elastomer-based soft robot. The obtained twist-bend crawling robot not only exhibits in situ rotation, four-way turning, and four-way linear motion under light irradiation with four wavelength bands (520, 655, 808, and 980 nm), but also demonstrates the ability to avoid obstacles in complex geographical environments. This work may bring a new perspective for fabrication and development of soft robots that can adapt to dynamic and complex environmental conditions.     

ADXL203型双轴加速计在机器人足部感知系统中的应用

仿人机器人要实现在复杂环境下稳定行走,仅仅依靠地面反力信息远不能满足应用要求,此时足部的倾角信息显得更为重要。脚面倾角可以反映地面倾斜状态,是仿人机器人稳定控制的一个重要依据。利用ADXL203双轴加速度传感器与DSP(TMS3202811)实现对倾角信息的实时高速采集与处理,并通过实验证明了倾角传感器在机器人足部感知系统中是可行的。     

基于高密度测量的Internet包延迟标度行为分析

通过对测量间隔为10ms的Internet路径往返延迟测量数据的分析，发现了往返延迟呈现两类截然不同的特性：突发态特性和平稳态特性。通过DFA分析，进一步得出以下结论：Internet路径往返延迟序列不具有单一的标度行为；剔除突发态数据后的往返延迟序列趋向于呈现长程相关特性，Hurst指数在0．55～0．8之间。

A Novel Protein Is Lower Expressed in Renal Cell Carcinoma

Engrailed-2 (EN2) has been identified as a candidate oncogene in breast cancer and prostate cancer. It is usually recognized as a mainly nuclear staining in the cells. However, recent studies showed a cytoplasmic staining occurred in prostate cancer, bladder cancer and clear cell renal cell carcinoma. The inconsistency makes us confused. To clarify the localization and expression of EN2 in renal cell carcinoma, anti-EN2 antibody (ab28731) and anti-EN2 antibody (MAB2600) were used for immunohistochemistry (IHC) respectively. Interestingly, we found that EN2 detected by ab28731 was mainly presented in cytoplasm while EN2 detected by MAB2600 was mainly presented in nucleus. To further investigate the different patterns observed above, lysates from full-length EN2 over expression in HEK293T cells were used to identify which antibody the EN2 molecule bound by western blot. Results showed ab28731 did not react with the lysates. For this reason, the novel specific protein detected by ab28731 was not the EN2 molecule and was named nonEN2. Then using the renal carcinoma tissue microarray and renal tissues, we found that the protein expression levels of nonEN2 in kidney tumor tissues was significantly lower than that in kidney normal tissues (p < 0.05), so was in renal cell lines. Taken together, nonEN2 is lower expressed and may play an important role in renal cell carcinoma.
