Description
hardware flow control. It is an ideal choice in the field of industrial automation.Core Algorithm 12 “The algorithm is not refined, domestic industrial robots are a bit “stupid”” (Science and Technology Daily, May 22)
China has been the world”s largest robot application market for five consecutive years, but high-end robots still rely on imports. Due to the failure to
master the core algorithm, key indicators such as stability, failure rate, and ease of use
of domestic industrial robots are far inferior to those of the “four major families” of industrial robots: Fanuc (Japan), ABB (Switzerland), Yaskawa (Japan),
and KUKA ( Germany) products. The core algorithm gap is too large, resulting in poor stability of domestic robots and high failure rates. The algorithm gap
is not only reflected in the core controller, but also slows down the response speed of the servo system.
Every time the robot completes an action, it requires the core controller, servo driver and servo motor to work together. For a single servo system,
domestic robots have high dynamic and static accuracy. However, high-end robots generally have more than 6 servo systems at the same time, and it is
difficult to achieve good control effects using traditional control methods.
High-end bearing steel 13 “High-end bearing steel, a shortcoming in China”s manufacturing industry that is difficult to make up for” (Science and Technology Daily, May 25)
As an indispensable core component in mechanical equipment, bearings support the mechanical rotating body, reduce its friction coefficient, and ensure its
rotation accuracy. Whether it is aircraft, automobiles, high-speed rail, or high-precision machine tools, instruments and meters, bearings are needed. This places
high demands on its accuracy, performance, lifespan and reliability. Our country”s shaft-making technology is close to the world”s top level, but the material – that is
, the steel for high-end bearings – is almost entirely dependent on imports.
