摘要： An anti-collision detection method for sweeping robots, which includes following steps. Step 1: preparing a sweeping robot provided with a Micro-Electro-Mechanical System (MEMS) device comprising an accelerometer and a gyroscope; skipping to step 2 when the sweeping robot is in a linear motion state and collides with an object; skipping to step 3 when the sweeping robot is on an external bumpy road; and skipping to step 4 when the sweeping robot is in a rotating motion state and blocked by an obstacle.

摘要： The present disclosure provides a sweeping robot obstacle avoidance treatment method based on free move technology, step 1 and step 2 are as following. Step 1: predetermining a sweeping robot provided with a six-axis gyroscope, a grating signal sensor, and a left-and-right-wheel electric quantity sensing unit. Step 2: performing a real-time sensing and data acquisition on an operation state of the sweeping robot by utilizing the six-axis gyroscope, the grating signal sensor, and the left-and-right wheel electric quantity sensing unit to obtain a real-time data information.
