Product Advantages — Reachy 2 Parallel Gripper

1. Reachy 2 Professional Gripper Technology

   PincOpen is derived from Pollen Robotics Reachy 2’s professional-grade gripper technology, achieving significant cost reduction while maintaining core functionality.

2. Replaceable Fingertip Design

   Fingertips support replaceable TPU material, allowing customization for different application scenarios.

3. Feetech STS3215 Servo Motor

   The same servo motor used in the SO-ARM101 robotic arm, directly replaceable for the SO-ARM101 gripper section. The STS3215-C018 servo provides data feedback and protection for angle, temperature, voltage, current, and load, capturing positions at any 360° angle in real time, with an alarm indicator light.

4. Adjustable Camera Mount

   Compatible with zoom 30FPS and fixed-focus 60FPS cameras. After securing the camera mount, the camera angle can be fine-tuned to accurately cover the robot arm’s working area.

5. Compatible with SO-ARM101, LeKiwi, XLRobot Arms

   Fully compatible with SO-ARM101, LeKiwi, and XLRobot open-source robotic arms, using the same motor for true plug-and-play integration.

STS3215 Motor Configuration Guide

Configure the motor ID to 6 before use. Please follow the steps below:

1. Install the LeRobot library
2. Connect the motor and power on
3. Run the motor configuration script

Important: perform midpoint calibration!
