3.Calibration offset

Must Read Before Use

Must Read Before Use

1、Calibrate Robotic Arm Offset

Strictly follow the steps below.

1.1、Use APP to Calibrate Robotic Arm Neutral Position

Access the container. If the APP is already running, open the mobile app YahboomRobot, enter the IP address, connect to the robotic arm, click Arm Settings - Servo Calibration, and follow the prompts to calibrate the neutral position of the robotic arm.

If the APP is not running, enter the following command in the container to start the APP, then proceed with calibration:

python3 /home/yahboom/APP_DOFBOT_PRO/YahboomArm.pyc

2.2、Use Calibration Program to Calibrate Offset (Only required if adjusting the initial position of the robotic arm for 3D spatial grasping; skip the tutorial below for other cases)

If you are missing the package, you can download the source code from the online repository provided. Place the source code into ~/dofbot_ws/. If you already have this package, you can ignore this step.
