With the progress of edge artificial intelligence, micro transmission system can help service robot to optimize gear and space in terms of performance and power consumption. Micro reduction motor has the advantages of low cost, high efficiency, low noise and long service life. This can be actively deployed in the field of service robots. For example, an autonomous humanoid server robot.
In addition to the interaction between many components, the main challenge for the autonomous motion of humanoid robot is the power supply and the space required by each component. Micro transmission scheme is the solution to this key problem. They have considerable power density, combined with high efficiency and minimum required space, improve the torque, so that the robot can move flexibly for a long time.
Service robots have only recently emerged. They are usually used to replace human activities. Most of them are mobile or semi mobile; Some professional service robots have manipulators that handle light loads or take complex actions. At present, there are some challenges that limit the practicability of professional service robots. These include: performance limitations: some “process intensive” activities require complex processing – there is still room for improvement in interaction quality and accuracy. In addition, there are battery capacity constraints: mobile professional service robots rely on batteries, and power often limits their achievements.
For battery powered robots, it is impractical to use traditional chips to consume hundreds or even kilowatts of power to run mobile machine learning algorithms. There are also connection limitations: it is often difficult to maintain a reliable connection of professional service robots that usually need to move. Connecting through wires is a solution, but it limits mobility. Wi Fi is a cheap option, but it can not guarantee the quality of service, and the switching between access points is usually unreliable. In addition, there is a delay problem in 4G network connection, which limits the robot’s ability to respond quickly. In addition to the above, improving robot vision and flexibility to promote effective mobility is also a challenge to be solved.
Shenzhen Zhaowei electromechanical Co., Ltd. (hereinafter referred to as “Zhaowei”), as a manufacturing enterprise developing and producing precision transmission systems and precision gear injection molding parts, adheres to market-oriented and technological innovation as the core, combines market demand with product R & D, and constantly meets the differentiated needs of global intelligent manufacturing customers.
Through the development of wear-resistant material technology, process optimization technology, lubrication technology, assembly technology, reliability and life detection technology and the exploration of transmission mechanism, Zhaowei has developed efficiency, small volume, large torque and low noise reducer (Gearbox) suitable for robot application, which has greatly improved the performance of Intelligent Robot Perception and recognition, mechanism and transmission, control and interaction.
In the aspect of robot wheel driving, the antisymmetric installation mode is combined with DC motor and 38mm planetary gearbox. This method can reduce the force point of the output shaft of the reducer, greatly shorten the wheelbase and save space, so as to miniaturize the volume of the robot. Due to this installation method, the selection of motors can be more extensive. Zhaowei uses 38mm metal reducer motor to increase torque and reduce speed. It can also use the friction self-locking between to brake when it needs to stop, and extend the wheelbase to meet the installation needs of wheel sets. The steering wheel adopts electromagnetic brake, which can be locked in case of power failure or released manually.
The two driving motors control the left rear driving wheel and the right rear driving wheel respectively, so that the robot can better complete the steering task. At the same time, the ultrasonic ranging sensor and infrared obstacle avoidance sensor are installed on the device, so that the robot can find the obstacles in front and turn to avoid in advance, so as to solve the problem of poor ability of turning and avoiding obstacles of the wheeled mobile robot.
In terms of robot vision system, Zhaowei uses camera lifting or rotating module to solve the disadvantages of visual navigation technology, which not only solves the cost, but also improves the reliability and service life of robot products.
In the past two years, service robots have been very popular in the retail, hotel, health care (such as exoskeleton) and logistics (in warehouse or distribution places). These robots can also be used in safe operating environments, such as space and national defense, as well as the construction industry (especially for demolition purposes). It can also be widely used in agriculture, such as automatic sowing, harvesting and weeding. Despite the growth achieved in the past decade, some technical obstacles still need to be overcome to make service robots truly enter the mainstream. Now and in the future, Zhaowei will help intelligent robots realize intellectualization and scientization in micro transmission system.
