Fixies VS Crabots (2019) on Netflix

Plot summary

Professor Chudakov invents, and he keeps a secret. The Fixies, the helpers who work with him, are known to no one else. He and Erica, his college sweetheart, once competed for the university's Grand Prize in 3D printing, and he took it. Now she comes to him with a warning: she will tell the world that the prize was not his alone. She proposes a rematch between the two professors to settle which of them is the better inventor. Chudakov calls on his Fixie friends for the contest. Erica brings helpers of her own: crabbots, robotic crabs that are stronger and quicker than the Fixies.
