These curved cradle blocks were designed to support an arm or forearm while experimenting with positioning, ergonomics, and motion using the Little Linkage Set.
The cradle surface is shaped as a shallow curved support that comfortably holds the arm, while the rear of the block includes a Little Linkage mounting interface. This allows the cradle to be attached to linkage arms and repositioned easily using standard M5 hardware.
By combining the cradles with linkage components, you can quickly prototype different support positions or constrained ranges of motion before committing to a final design.
What These Are For
These parts are intended as ergonomic prototyping tools, useful for exploring:
arm support positioning
reach and motion ranges
assistive input placement
fixture layouts
ergonomic experiments
The cradles can be repositioned by adjusting the linkage configuration.
How It Works
Each cradle includes a rear mounting interface compatible with the Little Linkage Set, allowing it to be attached to:
straight linkage bars
lever-style links
slide links
anchor mounts
custom linkage assemblies
This makes it easy to configure:
fixed support positions
adjustable supports
limited motion ranges
experimental arm positioning setups
Designed for use with:
M5 bolts
M5 nuts or threaded inserts
Little Linkage Set components
Possible Uses
Assistive input experimentation
Ergonomic arm positioning tests
Control interface prototyping
Physical therapy experiments
General fixture design
Notes:
These parts were originally created while exploring assistive interface layouts alongside other Off-Peak projects such as DriveKeys.
They are not intended as finished medical supports, but rather as adjustable prototyping tools for exploring ideas quickly.
