[Hangshun Training Camp] Intelligent Environmental Exploration Vehicle

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 is an environmentally intelligent car with multiple functions and a full sense of technology. Let’s start introducing the functions; Functions: 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 matched with the front end. The camera is used for remote terrain survey; 2: Temperature and humidity measurement uses DHT11 to collect the surrounding temperature and humidity and then transmits it back to the control terminal to view the surrounding environment temperature and humidity in real time; 3: The robotic arm uses a robotic arm model and a steering gear to realize the robotic arm For control, PCA9685 is used for PWM control of the servo, and any two IO ports can be used to control multiple servos; 4: The camera uses a wifi camera for image transmission, and a servo is used to control the camera rotation to adjust the image (the camera is broken) , prepare for repair, the repair is completed and will be perfected, so I won’t demonstrate it yet) 5: Offline voice control

    Using Qiyingtailun's offline voice board to control the car, we can temporarily control the direction, move forward, and report temperature and humidity. The firmware has not been finalized yet; there is still a development port and room to add functions. The front end of the robotic arm grabs the action. Because I The power of the steering gear is too small and it has not been implemented yet.

Finally, it’s strange. I was still using it when debugging, but today I couldn’t find my OLED screen. I gave up and stopped looking for it. I just read out the temperature and humidity, motion status, speed and other information on the car and then The display screen displayed on the remote control is nothing, it is also reflected in my program; I will not demonstrate it and buy a new screen@@@@
