【94】128 days to rewrite the decade-long technological barriers in Europe and America

Inside the gratitude gift box of a certain company lies a memory card. When inserted into the computer, 128 days of surveillance footage was compressed into 18 minutes: On the 3rd day, our engineers were lying on the floor of the EMCS laboratory of a certain company adjusting the grounding wire; on the 27th day, both teams were having a meal of instant noodles in the meeting room at 3 a.m., arguing over the resonant peak; on the 79th day, when the robot dog completed the 100th fall self-recovery test in the rain and muddy ground, everyone was soaked through but laughing. At the end of the video, a line appeared: "You are not delivering parts, but are jointly writing the chronicle of Chinese robots in our presence."

But the story's beginning was full of tension. When the purchasing director of a certain company visited for the first time, he didn't bring the requirements document, but three failure analysis reports of competing products. "A company had a coil cracking in the vibration test, B company's product had a false alarm rate of 37% under electromagnetic interference, and C company's temperature drift curve was like a roller coaster." He pushed the report over and said, "Why is Golden Eagle different?" I pressed the remote control and the large screen lit up the vibration test video we provided for the space station payload - on the same vibration platform, our coil experienced continuous 240-hour testing and the signal attenuation was only 0.3 dB. The meeting room suddenly fell silent.

Behind this silence was the unspoken predicament they didn't mention: a certain company's robot dog needed to enter the global high-end market within three years, and radar perception stability was a key indicator that European customers would reject without hesitation. A Japanese colleague had been outspoken: "China can make robots flexible, but it can't produce reliable 'machine vision'." So when a certain company chose us, they were betting not only on the security of the supply chain, but also on the dignity battle of whether Chinese robots could achieve a breakthrough in the perception dimension.

True trust was established in the seventh joint test. The robot dog was in a simulated ruins scene, needing to continuously cross steel mesh, crushed concrete and waterlogged areas. At the 4th hour, the radar suddenly showed periodic noise. Both engineers argued until the early hours of the morning, and finally the root cause of the problem was found - it was that the PWM frequency of the company's new generation motor and our coil's inherent frequency produced harmonic resonance - this was a cross-border problem that would not be recorded in textbooks. That night, we burned seven test boards, and the CTO of a certain company decided to postpone the motor production plan on the spot. When we parted ways, he patted me on the shoulder and said, "Today I finally believe that we are on the same boat."

The most shocking reward occurred at this year's Munich Robotics Exhibition. The demonstration area of the robot dog of a certain company was surrounded by people, when it jumped down from a two-meter-high platform and landed steadily, and then accurately identified all obstacles in the test area filled with radio frequency interference, European purchasing representatives raised their mobile phones to shoot the real-time imaging of the radar - the image showed even the outline of the screws clearly. At the celebration banquet that night, the overseas marketing director of a certain company came over with champagne and said, "The technical representative of German Bosch asked me, is your radar supplier a European enterprise?" He winked and said, "No, it's a company more crazy than us."

During these 128 days, we rewrote 11 internal process standards, obtained 3 joint patents, and more importantly, we and a certain company jointly proved that the Chinese supply chain can not only be a "follower", but also a "definer". When the robot dog of a certain company completed those breathtaking performances on the global exhibition stage, every obstacle precisely perceived by the precise sensing was silently telling one thing: Some limits exist for the purpose of being broken.

With 128 days to redefine the boundaries of robot vision - Golden Eagle and the brave together challenge the precision peak that no one has reached.
