10/6/2023 0 Comments Follower robot![]() ![]() This other video shows the assemble process. This videos shows the follower line robots in operation. This is the track test in opposite side of schematic. LM393 controls the 8550 transistors as switches and the latter controls DC motors, the D1 and D2 LEDs serve to indicate that the motor is on. The sensors output go to LM393 chip, which is a double voltage comparator, has two operacional amplifiers, the operation of this component will be subject to other post. The potentiometers have the function to regulate response of sensors. This robot uses 2 LDRs and 2 red LEDs as sensors. These are all components, the board is the chassi. This is the test track, has 4.8 cm width. The board after the processes of drawing, corrosion and piercing.Īll components, with the exception of TCRT5000 were welded in the trails side. This buttons opens the post about how to make printed circuit board. ![]() If robot goes too fast, it won`t be able to make curves. The diodes serve to reduce motor`s speed. The 47 Ω resistor serves to avoid TIP122 from heating up. When the phototransistor receives the reflected light from IR led, the TIP122 transistor is in cut mode and motor stops moving. This is the schematic circuit of electronic part. 4 AA batteries and support for 4 batteries.2 wheels and 2 DC motors with reduction.In a competition of this type, the added challenge is that the robots have to compete against time, and the fastest wins the competition. 6 resistors: 2 of 47Ω, 2 of 330 Ω and 2 of 10 kΩ Line following robots are one of the most simplistic types of robots that performs a simple task: tracking a black or a white line on a white, respectively on a black surface.It is possible to build a line follower robot with only 2 BJT transistors. IR sensors Click here Line follower with transistors In general robots incomes are voltages of. And they really don't follow a physical line. I'm just enthusiastic by seeing some sci-fi videos which show robots carry goods and materials in a crowded place. The construction and operation of this type is the post’s subject.Ĭlicking in the button below will open the post about IR sensors. The following robot is a intelligent system as a kind of provisional one, which has robot positions corrective feedbacks, toward the black or white line. 11 I would like to build a robot which follows a virtual path (Not a visible path like a 'black line on a white surface', etc). With infrared (IR) sensors, can build a line follower robot.
