AI Panda Chatbot, unable to receive the necessary verification code.

Jully — Thu, 26 Mar 2026 02:10:33 +0000

Question:
After connecting the device to Wi-Fi, it is supposed to prompt for a verification code so that I can add it to xiaozhi.me. However, my device does not display the prompt at all. I have already performed debug logging from the device, but I am still unable to receive the necessary verification code.

Answer:

Your network connection may be poor or slow. Please wait a while before you are taken to the verification code screen .

Or pls change to a different WiFi or get closer to the WiFi router.

For multiple Crowbots, how to ensure each joystick is only connected to the Bluetooth of one Crowbot

Jully — Thu, 29 May 2025 02:59:31 +0000

To ensure that each joystick pairs only with its designated CrowBot without interference, you can modify the factory code by assigning a unique set of 4 BLE UUIDs for each joystick-CrowBot pair.

Specificly, Please refer to the following information:
1 You can generate unique UUIDs using the following website:

https://www.uuidgenerator.net/
Then, Upload the corresponding modified program separately to the CrowBot and the joystick.

2 To upload the code, please make sure to copy the content inside the "library" folder provided in the Arduino code package (from our Wiki) into your Arduino runtime libraries path. Then follow the instructions in the tutorial PDF included, as shown in the image below.

⚠ Important: When uploading the program to the joystick, please make sure to select "ESP32C3 Dev Module" as the board type, as shown in the image below.

Future of STEM Robotics in Education

makerandcoder — Thu, 04 Sep 2025 17:09:15 +0000

The application of STEM robotics kits in classrooms is a phenomenon that is only going to grow at a very fast pace. With more AI, IoT, and automation being part of everyday reality, students should be introduced to them early. Trends that will be observed are:
AI-Integrated Kits: Giving students the power to program robots using machine learning.
Cloud Based Learning: Involves students working on robotics projects with other remotely.
Cross-Curricular Integration: Applying robots to the lessons not only in STEM, but also in arts, geography, or even certificate of competence.
Sustainable Robotics Kits: Environment friendly, to learn environmental responsibility.

pico 2 starter kit -how to upload programs

Jully — Mon, 28 Apr 2025 04:20:29 +0000

**1.Use a cable to Connect the device to the computer.
**2.Download Code and Libraries
The code and library files have been updated. Please scroll to the bottom of the following page and download the files from the red-highlighted section as shown in the screenshot:
https://www.elecrow.com/wiki/All-in-one_Starter_Kit_for_Pico_2_with_Common_Board_design.html

**3.Please place the downloaded library files in the Arduino runtime library path.

Here's how to do it:
Go to File > Preferences in the Arduino IDE. In the "Sketchbook location" field, copy the path shown there and paste it to any blank document file and then add “\libraries” to the end of the path — this is your Arduino runtime library path.

Open this path in the computer file folder, then copy and paste all the contents(as shown in the image below) from the Libraries folder you downloaded into it.

**4.Double click the .ino file in one lesson folder from the code we provided to open it in Arduino IDE .
for example:

**5.Board installing and selecting
(1) Configure Additional Boards Manager URLs:
In the Arduino IDE, click on File → Preferences, then paste the following URL into the "Additional Boards Manager URLs" field:. Then Click OK.
https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

（If you need to add multiple URLs, click the icon on the right to open the pop-up window and add URLs. Different URLs need to be separated by line breaks, and then click OK.）

(2) Install the Required Board:
Click on Tools → Board → Boards Manager, search for "2040", and install the following board.
Make sure you have installed version 4.2.0 of the Raspberry Pi Pico / RP2040 / RP2040 board package in the Arduino IDE. Use other versions may cause errors.

(3) Click Tools → Board,Select the Board "Adafruit Feather RP2350 HSTX" as shown in the following image :

**6.Enter bootloader mode manually using the following method:
Step 1: long Press and hold the BOOT button, then short press the RESET button.
Step 2: Release RESET first, then release BOOT.

**7.In the Arduino IDE, go to Tools > Port, and select the port labeled “UF2_PORT”, as shown in the screenshot below.

**8.After completing the steps above, click “Upload” icon in the Arduino IDE to upload the program.
