So

Can dance, sell cute "Ben Ben"

Where do you come from?

In order to let "BenBen" know the way, a set of positioning system was temporarily developed

The R&D team of "BenBen" comes from Yushu Technology in Hangzhou, Zhejiang. This "Ben Ben" performance is the first domestic dance performance of a high-performance quadruped robot cluster.

Since October last year, nearly 20 young people in the team have been working day and night. The person in charge Wang Xingxing said, "For a while, many colleagues only sleep for two to three hours a day."

For the first rehearsal in January this year, the R&D team came to Beijing with 60 "Ben Ben" rushed out of work, and was blinded as soon as they saw the stage. A single "Ben Ben" dance is easy to do, and dozens of them dance together, and a lot of technical problems are looming.

How does "Ben Ben" enter and exit the stage smoothly and keep the formation intact when hundreds of actors enter and exit the stage?

How to move and dance in line with the actors and the rhythm of the music in the performance?

The person in charge Wang Xingxing said, “We need a global positioning system, but we do not have this system.” So the team temporarily developed a new system by itself, which combines the currently mature two-dimensional recognition technology, infrared backlight technology, and image Recognition, etc., combined with the calf’s position and parameter data for integration.

After going through all kinds of things, small A overcomes in a short time:

1) Centimeter-level (or even millimeter-level) real-time mobile positioning problems for super-large stages

2) Multi-machine wireless communication problems in the case of strong electromagnetic interference on the stage

3) Wearing a complete set of beautiful clothing, the whole machine is too heavy, and the backflip power is insufficient (the dynamic parameters of the whole machine are changed)

4) The slippage of the backflip on the smooth glass stage

Wait for the question.

For the final effect of the Spring Festival Gala, Wang Xingxing, the person in charge, said that it has greatly exceeded the original idea.
