51Talk Star and technology rookie hit a different spark
RoboTerra is a STEAM education company based on professional programming learning and robot manufacturing in C language. In addition to having a very international entrepreneurial team background, there is also a special Chinese name called radish too spicy. Although less than five years old, RoboTerra is well known in the technology education industry. The radish is too spicy to provide a global robot education platform for students, teachers and educational institutions to stimulate their creative potential and enhance their overall quality.

I will learn the changes that I will bring to my own English.” The head of the 51Talk Study Tour talked about the reasons for choosing RoboTerra as an important stop for the study tour. He believes that the study tour should focus on diversity, with top-ranking universities, established large-scale technology companies, and of course should include technology rookies, and strive to make children worthwhile.
The little contestant Wang Yuanyi’s father lamented, “From Google to Apple, while experiencing the latest technology in Silicon Valley, I also appreciate the spirit of Silicon Valley, which returns to the essence of life, maintains a normal heart, and exerts creativity. Today, in the radish and spicy company, Computer scientists introduced to children that the evolution of robots reflects the progress of human civilization. The creativity and wisdom of various robots make us all amazed! 51Talk's study tour has benefited children." The radish is too spicy, and it is also a stage test of the English learning effect of the small players.
