As systems become more data-centric, monitors in industrial, iot, home medical wearables, fitness and health are experiencing explosive growth. These data-centric systems are increasingly demanding more features and lower power consumption. This trend is driven by intelligent systems that actively monitor a person or environment and make predictive responses, including alarms, actions, or recommended actions.
Giving the robot the ability to perceive and move the environment makes the robot safer and more mobile. If combined with Artificial Intelligence (AI) technology, it will make the robot smarter and more practical, making the future development of robots very imaginative space. This article will explore the development of robot perception and AI technology, as well as the related solutions introduced by many manufacturers.
If the robot wants to move autonomously, it needs to have 3D perception (3D perception) function, and various sensors must be used to grasp the position of the robot in space in real time, among which LiDAR (laser radar) can provide high-precision position sensing, which has received the most attention from the industry. In addition, the robot also needs to be driven by motors to perform precise movements of itself or its limbs. This article will introduce you to the development of LiDAR technology and the LiDAR and motor drive solutions introduced by ROHM.
After more than fifty years of historical development, the complexity of converting DC voltage into another DC voltage display in electronic circuits has continued to increase, and modern designs have incredibly high power density while increasing efficiency to maintain small power. RECOM has many innovative designs that apply high-power supply design techniques to low-power converters in small packages.
The robot must be equipped with multiple motors to be able to move the main body of the robot or the arms and limbs of the robot, which use the brushless direct current motor (BLDC) as the mainstream, in order to efficiently drive the brushless motor, it is necessary to choose the appropriate brushless motor driver. This article will introduce you to the characteristics and selection points of brushless motors and drives, as well as the product features of brushless motor drives from onsemi.
Power converter control plays a crucial role in optimizing the overall performance of a power conversion system. With proper control, the efficiency of the power converter can be maximized, energy loss reduced and component life extended. By designing a complex control algorithm, the power conversion can be effectively and optimally managed while keeping the output voltage and current of the power converter constant.

In addition, as automotive electric control units (ECUs) add connectivity and cloud computing capabilities, new solutions must be developed to address these technical challenges.
With the increasing demand for automation in the 21st century, robots are advancing at an unprecedented pace in numerous industries such as logistics, warehousing, manufacturing, and food distribution. Human-machine interaction, precise control and human-machine collaboration security are the cornerstones of automation adoption. Safe and precise control of the robot's multifaceted tasks, such as collision detection, obstacle avoidance and navigation, is achieved by a suite of sensors.
The main function of the battery management system (BMS) is to monitor cell voltage, battery pack voltage and battery pack current. In addition, given the high voltage design of the BMS, it is necessary to measure the insulation resistance between the high and low voltage domains to catch defects in the cell structure and prevent dangerous conditions from occurring.
BLDC motor is a rotary motor consisting of a three-phase armature winding on the stator and a permanent magnet on the rotor. The mechanical structure of the BLDC motor is opposite to that of the traditional permanent magnet brushed DC motor. The rotor is equipped with a permanent magnet and the stator is equipped with a motor winding. However, as the name suggests, BLDC motors have no brushes and require no regular maintenance or replacement, making them less susceptible to wear and tear
