As robotics continues to improve and evolve, more and more companies are beginning to source and use robots . How do you know which type of robot to choose? How to avoid the misunderstandings that we may not understand, even those that have been successful in application and not suitable for ourselves? Robot investments typically range from tens of thousands to millions of dollars, and it's important to make the right choices at the first time and avoid common mistakes, as errors can lead to unnecessary expenses or delays in tasks. To help engineers and designers avoid the most serious mistakes, the article lists the top ten pitfalls that robotic applications avoid. Misunderstanding 1: Underestimating the payload and inertia The first mistake in the application of robot users is to underestimate the payload and inertia requirements. Usually it is mostly caused by the weight of the tool installed at the end of the robot arm when calculating the load. The second reason for this error is to underestimate or completely ignore the inertial forces generated by the eccentric load. The inertial force may cause overload of the robot shaft. In SCARA robots, overloading of the rotating shaft is very common. Failure to correct this problem can also cause damage to the robot. This can be compensated for by reducing the load or reducing the speed parameter. However, reducing speed will increase unnecessary cycle time - the cycle of reducing the return on investment is the top priority in purchasing robots. This is why load-related factors are very important from the start. Yu Renpoli: The payload is very important. Some information given by the general technical parameters of the robot has a detailed description. The rated load is valid at the rated speed. One of the important conditions for achieving the maximum load is to divide. Low robot running speed, and excessive load may also damage the accuracy of the robot. Optical Line Terminal (OLT)
POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) The technology that can provide DC power for such devices while transmitting data signals is a switch that supports Power over Ethernet.
POE is also known as a power supply system based on local area network (POL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet for short. This is the use of existing standard Ethernet transmission cables to transmit data and data at the same time. The latest standard specification of electric power, and maintains compatibility with existing Ethernet systems and users. The IEEE 802.3af standard is a new standard based on the POE of the Ethernet power supply system. It adds related standards for direct power supply through the network cable on the basis of IEEE 802.3. It is an extension of the existing Ethernet standard and the first international standard for power distribution. standard.

IEEE began to develop the standard in 1999, and the earliest participating vendors were 3Com, Intel, PowerDsine, Nortel, Mitel and National Semiconductor. However, the shortcomings of this standard have been restricting the expansion of the market. Until June 2003, the IEEE approved the 802.3af standard, which clearly stipulates the power detection and control items in the remote system, and connects routers, switches, and hubs to IP phones, security systems, and wireless LANs through Ethernet cables. The method of power supply for points and other equipment is regulated. The development of IEEE 802.3af includes the efforts of many company experts, which also allows the standard to be tested in all aspects.
The IEEE 802.3at standard was formulated in 2005 and promulgated in 2009. The 802.3at standard output power can reach 30W, and the available power at the receiving end is 25.5W.
The IEEE 802.3 working group and various manufacturer alliances launched POH-POWER OVER HDBASET in the industry at the end of 2012.
Using the current 4-Pair four-pair wire technology plus, the bilateral power supply can reach 60-100W power, which can be achieved by using 5 or 6 types of wires. It is used in high-definition video promotion to supply power to 42" LED TVs. According to the new regulations in 2010, the power consumption of 42" LED TVs needs to be less than 70W.
