1>.Install circuit

1.1 Install metal film resistor,DIP-8P IC socket,Self-Locking switch,Potentiometer,S8550, Capacitor, Red LED on PCB according to mark on PCB

1.2 Install Mecanum wheel

The support bolts of the caster are inserted into the hole, tighten the nuts screwed into the caster, and finally fit the caster and tighten.

1.3 Install photoresistor and white LED on PCB reverse

1.4 Install battery case

1.5 Testing

Install 2pcs AA battery

Press on switch.If 2pcs white LED ON,the installation is successful.If LED off,please check the welding.

2>.Install mechanical parts

2.1 Install the four gaskets on the circuit board

2.2 Insert a steel shaft from the center hole of the wheel and note that the direction is inserted from one side of the raised sleeve of the wheel. It is better to insert the steel shaft parallel to the smooth side of the wheel

2.3 Put a three-way sleeve into the steel shaft, close to the wheel, and then a gasket into the steel shaft, close to the three-way sleeve, installed in place, toggle three-way sleeve, should be flexible. 

2.4 Place a gear into the steel shaft in the center of the steel shaft

2.5 Put a three-axis sleeve into the end of the steel shaft so that the car side of the wheel assembly to complete

2.6 Install Motor

3>. Testing

  3.1 Power on.Check S8550 or 10ohm resistor if motor don’t move

  3.2 Install LM393

Product Features

• 【Wide – Application】Smart robot car is the most widely used in school for helping students to learn about the soldering project knowledge of mechanical structure, electronic basis skills, the principle of sensor, automatic control, soldering skill and so on
• 【Easy Assembly】The operating principle is provided as above picture shown and we provide electronic manual for you. It’s much easier to assemble which is great for kids, begginers and hobbyist.
• 【Its Principle】As the light reflectivity is difererent when the light is emitting on the white and black items. It uses the photoresistance resistance to tell the smart car is on the right way or not. Smart tracking car can discriminate the direction automatically that it can run freely along the black tracking line.
• 【Design Your Runway】You can also use the 1.5~2.0 cm black electrical tape directly on the ground to design the complex runway. It would be even more fun!
• 【English Manual】Contact us to get PDF manual or download the installation from drive.google.com/open?id=1kLlV2NlXQeXo56ItreQ1JlUParTRc-16
