smart car

1. Prepare to complete the car picture exhibition test

2. Function Description 1. Automatically has obstacle avoidance function.

2. Automatic tracking function.

3. PS handle remote control function.

4. Complete remote control through 2.4G remote control module (subsequent improvement, homemade remote control)

3. Description of circuit design process

The circuit diagram design uses the circuit used on Lichuang's car to complete the component selection. It mainly tests the speed control (PWM), tracking and obstacle avoidance of the car. Later, the function of improving the function will be added to the water gun firing function, and the car body will be added with sensors (used for scoring in the battle between two vehicles). Since I didn’t buy a Hangshun chip, I used an Arduino motherboard as the main control. Divide the trolley circuit board into small functional modules (PCB Figure 2). The disadvantage of using a module board is that there are too many connections.

4. Car body design is mainly designed using SW. First do your own 3D printing verification, and then prepare to go to Lichuang to build a perfect casing. (This process is a bit long) 5. First use the N20 motor to make a car chassis, and use the PS2 remote controller to complete the basic functions of the car. (The car chassis is a bit crude) 6. Use a TT motor and a Mackenham wheel chassis for control, and use an Arduino board for the main control. The casing is still under design. The function is being improved.

Continuously updated, I redraw the PCB board and draw an Arduino expansion board.
