Project details

Cell geometry, module response, measured loading, build state, and representative programmed motion from the current paper figures.

Cell and module response

  • Capped and uncapped cells are shown side by side across the same pressure sweep.
  • Pressure-driven expansion rotates compliant linkage legs while the integrated chamber supplies deformation.
  • The 2 x 2 module test reports single- and two-module bending angles separately.
Capped and uncapped cell geometry and pressure-driven expansion.
Cell expansion under pressure; capped and uncapped variants stay side by side.
Single-module and two-module bending under pressure.
Single-module and two-module bending response across the pressure sweep.

Measurements

Current paper figures and tables; figure-read values remain approximate.
Pressure-dependent force and stiffness data.
Force and stiffness curves for single cells and the 3 x 3 array.
Output force Approx. 40-50 N for single-cell tests; above 50 N for the 3 x 3 array near maximum compression. Fig. 5(a-c)
Local stiffness Approx. 5-7 N/mm peak local stiffness across cell and array plots. Fig. 5(d-f)
Planar height At 100 psi, 1 x 1 actuation reaches 60 mm max height; 2 x 2 actuation reaches 115 mm. Table 1
Boundary Loop area is not digitized here; current build remains tethered and manually assembled. Methods; Discussion

Build and test state

  • Printed cell bodies, caps, and snap-fit connectors are shown as physical parts.
  • Unit-cell and array load tests precede the surface and body demonstrations.
  • Electronic addressing is outside the current public build state.
Printed Sarrus module parts.
Printed module parts and snap-fit assembly.
Cell and array compression tests.
Compression tests for the unit cell and array.

Programmed motion

  • Local pressure patterns produce measured height maps and object transport.
  • The same cell array is wrapped into bending and locomotion assemblies.
  • The selected set keeps one planar height-map panel, one object-transport panel, one cylindrical bending panel, and one crawler sequence.
