The sweeping robots we are familiar with are basically circular. No matter how expensive or high-tech, it is always inaccessible when it encounters the position of the horn. In order to improve this, someone has designed a triangular sweeping robot.
The design of Jessica Won Choi shows this new triangular shape sweeper.
Although lacking the sense of sprouting of the round sweeper of traditional sweepers, its advantage is that its triangular shape allows it to sweep deeper into the corner when it encounters a corner.
