JUNE, 21st
- redesigned foot with single pivot
- we reduced the thickness and the components
- single pivot foot with exploded modular plates
we got inspired from some existing legs:
- the piston and the leg had 2 different attachment points
- the piston is free to move (it doesn't get in contact with the leg)
- the piston contribute to the solidity of the entire structure
- we read that was some structure doubts on the first version [[1]]
and a "double-beam" leg is distantly related to hollow section, so we think is could be more resistant
results:
- double beamed
- single-pivot foot
- free piston
- assembly
- we are still working on how to attach it to the pivot :(
for the leg is pretty simple but is more difficult for the piston (that must be higher)
JUNE, 20th
- we tried to reduce the modular plates 1. to save space and 2. to save material
so here's the versions of the modular plates (green first version, triple last version)
- the last version is thinner and have 3 steps for more adjustments
- we noticed that attaching the steps with some bolts will make some studs-like bumps that is kinda good for soft terrains.
JUNE, 19th
- We made a first concept of the stabilizer foot, based on a double pivot used for some mops;
my intention was to create a double axis adjustment on the terrain.
- Gary said me the piece was too difficult to machine, so I leave this first model as an "idea" for future modifications
- example of foot's movement (maybe it lose some strength with all this inclination)
- we thought also about a modular plate to increase surface if needed, for example on sand or other soft grounds.
- the plate can be disassembled to reduce occupied space and for applying more force if needed on solid grounds.
