How Does a Follower Robot Circuit Work?
Overview of the Follower Robot Circuit
- The video introduces the follower robot circuit, explaining its function in monitoring a black line using sensors to control motor speed.
- This technology is applicable in industrial settings and educational institutions for developing speed and dexterity skills.
Components of the Circuit
- The first stage involves sensors that detect the black line; a previous video explains how these sensors operate.
- When the sensor detects the black line, an LED turns off; when it returns to white, the LED lights up. This signal is transmitted via an orange cable connected to a CNY70 transmitter-receiver.
Transistor Configuration
- A 1k resistor connects from the CNY70 to a 2N2222A transistor, which has three legs: emitter (left), base (center), and collector (right).
- The emitter connects to ground, while another 1k resistor links from the collector to positive voltage. This setup allows for signal transmission to control motors.
Adjusting Motor Speed
- A variable resistor (50K) is included to adjust motor speed based on performance; if too fast or slow, this can be calibrated by changing resistance values.
- Another 1k resistor connects as the base of another transistor (2N2222A), with its emitter grounded and collector linked to a gear motor capable of at least 1 kg force.
Operational Mechanics
- When passing over a black line, the engine activates; if veered off course, it shuts down one side's motor while allowing the opposite side's motor to continue functioning.
