Overview

A suction cup combining vision and tactile sensing with wireless electronics. [S001]

FlexiCup combines suction with vision and tactile sensing. Its shared sensing structure supports two different pneumatic routes: vacuum for sustained-contact adhesion and Bernoulli actuation for contactless lifting. Select the actuation mode before sourcing air equipment or choosing the bottom assembly. [S001] [S004]

Assembly and use

Start with the selected assembly

The reviewed revision is 0a23196e7b3afa5f6bdf7738558609f956016b69. Start with Hardware/Fabrication/CAD/FlexiCup_CAD_BOM.xlsx and Hardware/Fabrication/PCB/FlexiCup_PCB_BOM.xlsx, then match the assembly and circuit to that revision. Bottom configurations I–II are for vacuum and III–IV for Bernoulli operation. [S001] [S003] [S004]

Upstream describes a 750 W, 140 L/min vacuum pump with −90 kPa maximum vacuum, and an 800 W, 65 L/min compressor at 0.8 MPa for the other mode. These describe its reported equipment, not independently verified minimum requirements. Solenoid valves, connections and the selected supply still need procurement reconciliation. The fabrication guide describes a PLA FDM top housing; other optical and elastomer parts require their own material and fabrication checks. [S004] [S005]

Electronics and reuse boundaries

The repository lists PCB manufacturing files, ESP32-S3 firmware and a learning pipeline. File presence does not establish a complete revision-matched electronics, firmware or software setup; matching weights and data also remain unverified. No universal arm mount or pneumatic interface is assumed. [S001] [S003]

CC BY-SA 4.0 is the README's project-level declaration. Bundled diffusion and camera components have separate license files, whose terms were not fully assessed here; do not treat the README declaration as blanket coverage for those components. Consult those notices before reuse. No current complete cost, hardware build or performance test is established by this profile. [S001] [S003]

Cost

No current, complete configuration-specific build cost has been established for this profile.

Source files and licenses

Source-researched component coverage; complete build, commercial rights and performance qualification remain separate.
