{"product_id":"sparkfun-robotic-finger-sensor-v2","title":"SparkFun Robotic Finger Sensor v2","description":"\u003cp\u003eDoes your robot crush objects with its hulkishly strong grip? Give your robotic hand or claw a better sense of touch with the Robotic Finger Sensor. This new version adds pressure sensing so now you can know how hard you're gripping!\u003c\/p\u003e \u003cp\u003eThe Robotic Finger Sensor (RFS) uses a unique combination of infrared distance sensing, pressure sensing, optical encapsulant, and data filtering to detect extremely light touches. Additionally, the silicon covering is squishy, giving the sensor increased grip (friction).\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHow does it work?\u003c\/strong\u003e IR light from the VCNL4040 distance sensor dramatically scatters when an object like a white coffee cup or human skin comes in contact with the face of the sensor. Once contact has been made the LPS25HB pressure sensor is able to quantitatively detect how hard the sensor is pressing against the surface. We've written fully featured Arduino libraries for the VCNL4040 and LPS25HB sensors. The example firmware demonstrates how to capture this signal and turn it into 'Touch' and 'Release' events.\u003c\/p\u003e \u003cp\u003eThe Robotic Finger Sensor ships fully encapsulated. The additional 'bare board' photos are there only to show the detail of the sensors inside the clear encapsulant.\u003c\/p\u003e \u003cp\u003eThe RFS requires 3.3V and communicates over I\u003csup\u003e2\u003c\/sup\u003eC. The connector is compatible with our Qwiic system. The \u003ca href=\"http:\/\/www.sparkfun.com\/qwiic\"\u003eQwiic system\u003c\/a\u003e enables fast and solderless connection between popular platforms and various sensors and actuators.

Hot glue also works well.\u003c\/p\u003e \u003cp\u003eThis is a collaboration with Professor \u003ca href=\"http:\/\/correll.cs.colorado.edu\/\"\u003eNikolaus Correll\u003c\/a\u003e and Professor \u003ca href=\"http:\/\/www.segildesigns.com\/about\/\"\u003eJacob Segil\u003c\/a\u003e at CU Boulder. A portion of this sale is given back to Dr. Correll's lab for the continued development of innovative robotic components.\u003c\/p\u003e \u003cp\u003eThe Robotic Finger Sensor is the first piece of autonomous robotic control.

CU is working on an impressive \u003ca href=\"https:\/\/github.com\/correlllab\/cu-perception-manipulation-stack\"\u003erobotic perception stack\u003c\/a\u003e to make this easier for the beginner.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhat if I need more than one?\u003c\/strong\u003e The sensor has only one I\u003csup\u003e2\u003c\/sup\u003eC address so putting multiple on the bus will cause collisions. Luckily, we've got a mux for that! The \u003ca href=\"https:\/\/www.sparkfun.com\/products\/14293\"\u003eQwiic Mux \u003c\/a\u003e allows up to 4 sensors to be simultaneously connected with the ability to daisychain up to 8 muxes. 32 fingers is a big gripper!
