Description

technical field [0001] The invention relates to the field of robots, in particular to a motor drive circuit for a wheeled mobile robot based on multiple sensors. Background technique [0002] In recent years, the number of robots has increased year by year at an astonishing rate. According to data recently released by World Robotics, the total number of robots in the world has reached at least 8.6 million. All 8.6 million robots include 1.3 million industrial robots and 7.3 million service robots. Among them, the growth rate of service robots is very rapid, and the current number has reached 2 times that in 2006. And, if this growth can continue, the total number of robots will reach 13 million in 2012. These robots are mainly engaged in service, maintenance, maintenance, repair, transportation, cleaning, guardianship, etc., and their common feature is that they need to move in a specific working environment. At present, there are many solutions for robot movement, such as...
