【Racing Collection】Environmental Exploration Intelligent Car

Overview

Remote control part: https://oshwhub.com/Cwen/huan-jing-kan-tan-ju-yao-kong-qi-bu-fen

Front light part: https://oshwhub.com/Cwen/new-project

This is an environmentally intelligent car with multiple functions and a full sense of technology.

Start introducing functions;

Function:

1: The GT-24 module with power amplifier used for 2.4G remote control has an ideal transmission distance of 2000 meters. After testing, it can achieve effective control of about 400 meters in a wall-through corridor. It can be used with a front-end camera for remote terrain surveying. ;

2: Temperature and humidity measurement: DHT11 is used to collect the surrounding temperature and humidity and then transmit it back to the control terminal to view the surrounding environment temperature and humidity in real time;

3: Robotic arm: The robotic arm model is used together with the servo to control the robotic arm. PCA9685 is used for PWM control of the servo. Any two IO ports can be used to control multiple servos;

4: Camera: Use a wifi camera for image transmission, and use a servo to control the camera rotation to adjust the image (the camera is broken, and it has been repaired for half a month. I don’t know if it will be available during the award ceremony, so I won’t demonstrate it yet)

5: Offline voice control

Qiyingtailun's offline voice board is used to control the car. It can temporarily control the direction, move forward, and report temperature and humidity. The firmware has not been finalized for the time being. There is still a development port and room to add functions. The front end of the robotic arm can grab items just because My servo is too weak and can only hold light objects. I plan to get a stronger servo.

Haha, I received two books from the forum this morning.

EZ430-Chronos User Experience (1) - Acceleration Measurement
First of all, I must say that I was very excited to get this "watch". After opening it, I found a CD, a wireless transceiver with a USB interface ( 433MHZ ), a USB burner, a screwdriver, and the EZ430
