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.
