Let me start by saying I’m new to robotics and rasberry pi. Not a programmer so be gentle on me.
My son does like coding and models and remote control cars so I thought this would be a perfect gift for him.
Got him a picar-X V3 and a Raspberry Pi 4 Model B 4GB.
We built the robot (unfortunately didn’t 0 the servo’s because I didn’t understand that step at the time). We first used the paper instructions. Now it’s all built and we were able to charge the battery.
I was able to load the raspberry pi imager to a micro-sd and put it in the slot. I can see my router has connected to the raspberry pi. Now I’m trying to do the powershell step in the video with the SSH command, but it says “ssh: connect to host raspberrypi.local port 22: Connection refused”
I feel like I may be in over my head. Any tips? Are these steps necessary to use EZBlock? I nor my son are ready for python. I have EZBlock Studio on my phone, but it doesn’t see the device in bluetooth
1.First, configure the WiFi on your Raspberry Pi 4 (PI4). Your computer needs to connect to the same router’s WiFi so that both devices are on the same local network for a successful connection.
2.If you’re using PowerShell to connect to the PI4’s IP and the connection is refused, it’s recommended to use the PuTTY tool instead. Please refer to this tutorial for guidance: Using PuTTY.
After downloading PuTTY and connecting to the Raspberry Pi’s IP, follow our tutorial to install all the necessary library codes: Install All Modules.
Once all library codes are installed, restart the Raspberry Pi and run the servo adjustment commands in the terminal to zero the servos and secure them: Servo Adjustment.
We also have an assembly video for our product; you can follow the steps shown in the video: Assembly Video and refer to the assembly instructions here: Assembly Instructions.
If you want to control the PiCar-X using the EzBlock app, you’ll need to prepare a separate SD card and download our designated EzBlock OS image: EzBlock OS Download.
After installing EzBlock OS onto the SD card, please follow the tutorial to start it and perform the servo zeroing and assembly: Quick Guide on EzBlock.
