RPPS-256 - LEGACT

RPPS-256 Pressure distribution detection module

RPPS256 is a pressure tactile system based on the ARR-16X16-TC1-V1 sensor. It is mainly used in scenarios such as human-shaped robot fingers, providing the robot with tactile feedback, enabling it to sense the magnitude of force and preliminarily judge the smoothness or sharp protrusions of the object surface. It can also be coordinated with six-dimensional force sensors, temperature sensors, etc., making the robot’s tactile perception more refined and sensitive.

The entire process of pressure changes can be traced

This system is equipped with a thin-film piezoresistive sensor with 256 sensing points.
It is combined with the acquisition module developed by Force Sens Technology. It outputs TTL level signals,
which are converted by CH340 or CP2102 (USB to TTL module) for communication with the PC. Additionally,
it provides an upper computer that is convenient for users to test, which can display the AD values or thermal
images of each sensing point in real time.

Each capture can read the data

Based on the 256-point pressure distribution information, the system can make a preliminary judgment
on the flatness or sharp protrusions of the object surface. For the grasping and interaction scenarios of
humanoid robot fingers, this provides a tactile dimension reference for the identification of the object surface state.
