The human arm is a paradox of rigidity and flexibility, and there are many scenarios in life where a combination of rigidity and flexibility is required. For example, when hanging a picture on a white wall with a nail, a person will first grip the nail towards the wall, then pick up a hammer or … Read more
1. Why is the touchscreen inaccurate? a. It may be that the reflective stripes around the screen of the acoustic touchscreen are covered with dust after a period of use. Please wipe it with a dry, soft cloth, then turn off the power, restart the computer, and recalibrate. b. It is possible that the reflective … Read more
Follow 【指尖维修】 for fresh insights on motorcycle maintenance and repair! Author: 行思止随 Yesterday, we discussed how fuel-injected motorcycles no longer require ignition coils, as their functions have been replaced by the ECU, and we listed the four main functions of the ECU. Today, we will discuss the internal structure and workflow of the ECU. The … Read more
TechGear The ECU is the core of the electronic control system. It is essentially a microcomputer or microcontroller that receives signals from sensors on one hand, processes this information, and sends corresponding instructions to control the actions of actuators on the other hand. Sensors are components that perceive information, responsible for providing the ECU with … Read more

Quasi Direct Drive Actuators: Emerging Actuator Technology with High Dynamic Response 1.1 Quasi Direct Drive Actuators: Emerging Actuator Technology for Legged Robots The Quasi Direct Drive (QDD) actuator first gained public attention through the MIT Cheetah quadruped robot. The QDD is an emerging actuator technology that relies on … Read more
1 Introduction A year ago, I researched an embedded device and found its acoustic configuration logic quite intriguing, but later focused on vulnerability exploitation and did not delve deeper. Recently, while studying wireless communications like sub-GHz, Bluetooth, and RF, I became interested again in transmitting information via acoustic signals, which led to this article documenting … Read more
Cao HX, Nguyen VD, Park JO, Choi E, Kang B. Acoustic Actuators for the Manipulation of Micro/Nanorobots: State-of-the-Art and Future Outlooks. Micromachines (Basel). 2024 Jan 26;15(2):186. doi: 10.3390/mi15020186. PMID: 38398914; PMCID: PMC10890471. Compared to other actuation methods, acoustic actuators have the unique capability of non-contact operation of small objects (such as micro and nanoscale robots). … Read more
