Summary of the Circuit

This circuit appears to be designed for controlling gearmotors based on the input from IR obstacle sensors. It includes two FC-51 IR Obstacle Sensors that likely serve as the input devices to detect obstacles. The circuit also contains two KF-301 Relays which are probably used to switch the gearmotors on and off. The power for the circuit is provided by a pair of 18650 Li-ion batteries, and the voltage is regulated and boosted by two XL6009E1 Boost Converters. There are also four Gearmotor DC / Motorreductor components that are the actuators of the circuit.
