A Manta Ray-Inspired Biosyncretic Robot with Stable Controllability by Dynamic Electric Stimulation​


Biosyncretic robots, which are new nature-based robots in addition to bionic robots, that utilize biological materials to realize their core function, have been supposed to further promote the progress in robotics. Actuation as the main operation mechanism relates to the robotic overall performance. Therefore, biosyncretic robots actuated by living biological actuators have attracted increasing attention. However, innovative propelling modes and control methods are still necessary for the further development of controllable motion performance of biosyncretic robots. In this work, a muscle tissue-based biosyncretic swimmer with a manta ray-inspired propelling mode has been developed. What is more, to improve the stable controllability of the biosyncretic swimmer, a dynamic control method based on circularly distributed multiple electrodes (CDME) has been proposed. In this method, the direction of the electric field generated by the CDME could be real-time controlled to be parallel with the actuation tissue of the dynamic swimmer. Therefore, the instability of the tissue actuation induced by the dynamic included angle between the tissue axis and electric field direction could be eliminated. Finally, the biosyncretic robot has demonstrated stable, controllable, and effective swimming, by adjusting the electric stimulation pulse direction, amplitude, and frequency. This work may be beneficial for not only the development of biosyncretic robots but also other related studies including bionic design of soft robots and muscle tissue engineering.

仿生学是重要的机器人研究方法之一,通过模仿自然生物的结构和行为来提高机器人的运动学性能。而类生命机器人以天然生物材料为机器人核心要素,是仿生学的进一步发展。例如,一些活体细胞已经被用于实现机器人的部分功能,包括感知、控制、驱动等,其中驱动作为决定其性能的关键因素,关系到机器人的整体性能。然而要进一步发展类生命机器人的可控运动性能,还需要创新推进方式和控制方法。针对以上难题,研究人员提出了一种基于CDME的动态控制方法。该项研究以论文《基于动态电刺激的“仿蝠鲼类生命机器人”》(A Manta Ray-Inspired Biosyncretic Robot with Stable Controllability by Dynamic Electric Stimulation)发表在期刊《类生命系统》(Cyborg and Bionic Systems)上。









据悉,《类生命系统》是北京理工大学与美国科学促进会(AAAS)/Science 共同打造的高水平国际英文科技期刊,入选“中国科技期刊卓越行动计划高起点新刊”项目。

CRRC Maglev presentation at InnoTrans 2022 in Berlin, Germany. Too bad the Europeans won't have the money nor the electricity to operate them. As for China, the first demonstration line should be ready around 2025.
Great video by CRRC. Speed wise it seems to be equivalent to the Japanese Maglev system, wonder the cost side of things. If cost of Maglev can be controlled, it certainly have the chance to replace some short haul flights.

A short haul flight vs a Maglev train, I would definately take Maglev.

Alibaba doing some good things here.

Alipay+ now integrated with Korean vendors. I'm assuming this is a move that depends on KakaoPay's presence in South Korea. Generally, seems like Alipay+ is a great idea that will allow Ant group to have greater influence in this space.

More on the Alibaba's new cloud announcement. Looks like this allows them to really scale up for the future that will really allow them to grow. Now, they just to find more customers.

[The world's first carbon fiber rail vehicle bogie released]

CRRC report: On September 20, 2022, CRRC released the world's first track developed by CRRC Tangshan at the 2022 Berlin International Rail Transit Technology Exhibition. The "bow" of the traffic vehicle is a bogie.

The bogie adopts a fully assembled carbon fiber flexible structure without welding structure, which has good vibration damping characteristics and can improve the stability and comfort of the vehicle. Compared with traditional alloy steel and titanium alloy bogies, the power type of the "bow" bogie can reduce the weight by 25%, the non-power type by 35%, the vehicle running energy consumption by 15%, and the wheel and rail wear by 30%. The noise is reduced by 2-3 decibels, and the whole life cycle cost is reduced by 15%, which effectively improves the lightweight, low energy consumption and low noise of rail vehicles.

At present, carbon fiber composite materials are gradually becoming the main structural material of rail vehicles. The design process of large carbon fiber composite materials such as hood, windshield, cab, console, equipment cabin, skirt and other complex components is becoming more and more mature. Once widely used, China will only need up to 50,000 tons of carbon fiber materials for rail vehicles in the future.
