Overview

Designed for XLerobot robot arms, this SO-ARM101 TPU flexible gripper supports mounting of the SO-ARM101 arm camera mount/kit. The soft TPU material safely grasps irregular and fragile items without damage; optional camera configurations (zoom 30FPS / fixed 60FPS) serve grasping development and vision-guided applications.

Key features:

  • Direct installation on XLerobot arms, no modifications needed
  • Soft TPU: flexible, wear-resistant, non-slip — safe for fragile items
  • Compatible with SO-ARM101 arm camera mount/kit (vision-guided grasping)
  • Screw-direct mounting, plug and play
