Our colleague Vladimir Osipov equipped the SO-ARM100 parallel gripper with FSR402 force sensors to enable delicate object handling with real-time grip force feedback. The sensor detects forces as low as 0.2N, while the target grip force is tuned per object โ around 5N for a cherry tomato โ to account for the limited torque precision of STS3215 servos and prevent slipping. This allows the gripper to grasp soft objects gently, detect slippage, and automatically retry the grip.
