Pidadapter - Cello Robotic Arm Tuning Tool

Version Supported Environment Entry
v2026.02.14 Windows, macOS, Linux Open Web Configuration Tool

Overview

Pidadapter is a Cello robotic arm tuning tool developed by Fashion Star. It is used to connect to the robotic arm and configure serial parameters, with different power modes for different application scenarios.

Features

Device Connection

  • Serial connection: Connect to the robotic arm serial port through a browser
  • Recommended browser: Chrome or Edge

Power Mode Optimization

Three power modes are provided and can be selected according to actual usage:

Light Load Mode (Smooth Anti-Jitter)

  • Applicable scenario: No-load operation
  • Feature: Optimizes low-speed motion jitter and improves smoothness
  • Advantage: Smoother movement and reduced vibration

Standard Mode (Balanced General Use)

  • Applicable scenario: Routine operation
  • Feature: Balances force output and smoothness
  • Advantage: Good balance between performance and stability

Heavy Load Mode (High Rigidity)

  • Applicable scenario: Large end-load operation
  • Feature: Improves arm rigidity
  • Advantage: Stronger support and better load stability

Caution

  • Do not power off or unplug the data cable while writing parameters
  • Keep power supply stable during parameter updates
  • Any interruption may damage servo configuration

Detailed Operation Flow

Step 1: Open the Tool Page

  1. Click to open the web configuration tool
  2. After the page loads, the main interface will be displayed
Tool Main Interface

Step 2: Connect the Robotic Arm

  1. Locate the connect button
    • The top area is labeled "1. Device Connection"
    • Click the blue "Connect Robotic Arm" button
  2. Select a serial port
    • The browser will open a serial device selection dialog
    • Select the serial device corresponding to your robotic arm
    • Port name is usually /dev/ttyUSB* (Linux/macOS) or COM* (Windows)
  3. Confirm connection
    • Click "Connect"
    • Wait for the connection to be established
    • After success, the status changes from "DISCONNECTED" to "CONNECTED"

Step 3: Select the Appropriate Power Mode

Select a mode based on your actual use case:

Scenario Recommended Mode Reason
Robotic arm running without payload Light Load Mode Less jitter and smoother motion
Routine operation (moderate load) Standard Mode Balanced performance and stability
Heavy-load operation Heavy Load Mode Higher rigidity and less deformation

Steps:

  1. Select mode
    • Select the required power mode, then click after blue highlight [ ] appears
  2. Confirm write
    • A confirmation dialog appears: "Confirm writing parameters?"
    • Dialog note: Please keep power stable during parameter updates. Any interruption may damage servo configuration.
    Confirm Parameter Write
  3. Safety check
    • ✅ Confirm stable power connection
    • ✅ Confirm robotic arm data cable is firmly connected
    • ✅ Confirm no risk of power interruption nearby
  4. Execute write
    • Click "Confirm Write"
    • Or click "Cancel" to abort
  5. Monitor progress
    • The page shows progress: "Ready... 0%"
    • The progress bar increases gradually from 0% to 100%
    • During this process, do not power off or unplug cables
  6. Finish writing
    • The page shows "Configuration Successful"
    • Robotic arm parameters are updated to the new mode
    • You can start using the robotic arm
Write Completed

Common Issues and Solutions

Cannot connect to the robotic arm.
  • Possible causes:
    • Browser does not support Web Serial API
    • Serial device is not recognized
  • Solutions:
    • Use the latest Chrome or Edge browser
    • Check robotic arm power and USB cable connection
    • Try another USB port
    • Re-plug the robotic arm USB cable
Connection disconnects immediately.
  • Possible causes:
    • USB driver issue
    • Insufficient serial port permission
  • Solutions:
    • On Linux/macOS, try sudo chmod 666 /dev/ttyUSB*
    • Check firewall settings
    • Try running the browser with administrator privileges
Writing parameters fails.
  • Possible causes:
    • Unstable power supply
    • Loose data cable
    • Robotic arm not initialized correctly
  • Solutions:
    • Check whether power supply is stable
    • Ensure the data cable is firmly connected
    • Reboot the robotic arm and try again

Troubleshooting Checklist

Please confirm the following before operation:

☐ Robotic arm is powered on and running normally
☐ USB data cable is firmly connected
☐ Serial device is recognized
☐ Network connection is normal
☐ Power supply is stable
☐ Environment has no risk of accidental power interruption
