Soft Robotics – 10 items & Store Selfie

I decided to go to Home Depot for this assignment.

  2. Foam Sealant

The stretch sealant has a very strong adhesive but can stretch up to 600%. The foam sealant isn’t as stretchy but still retains some softness and has a really interesting look after it expands, weirdly organic.

I think it would be interesting to explore these materials with other soft materials in the direction of soft robotics or sculpture.

I love semi-translucent and translucent materials especially if there creates some sort of light refraction. This seems like it could have many different uses with projects or maybe some aspect of biomimicry.

This would be an interested application combined with silicone to inhibit certain areas and to act as conductive material embedded inside of it.

I’m very attracted to this material because it molds like clay, carves, sand and machines like wood which sound widely applicable for projects and / or sculpture. Could also be a great mold maker.

Clear materials that can house other materials fascinate me, maybe because they remind me of fossils in amber. A strong glaze can transform any material into something more intriguing.

I’d like to explore further the contact between foam and soft cushion materials with harder materials that act as a skeleton,

I’ve always been drawn to materials like this, probably for the potential movement that can mimic organic movement and also the effect on sound when it travels through it.

I would love to work more with soft materials and water and water pressure / pumps. I also just love the look of these clear tubes from a design standpoint.

Materials Connexion – Bacteria Cellulose

    • Email link
    • Image of material
    • Link to Material Connexion page
    • How does it relate to your Soft Engineering interests?
    • Soft Durometer/Flexibility/Elasticity/Other – Which properties does it have?
    • Distributors – Where can you buy it? If no distributor, how do you get in touch with manufacturer?
    • On label use?

 

I was drawn to this piece because it is a natural material and is tough. flexible and translucent. It is a bacteria cellulose, it feels kind of like a very thing leather but more gummy without being sticky. It’s produced as a secretion from bacteria that’s fed sugary solution in a warm bath which I find very interesting. I’ve seen mycelium made leather like material before, they could probably serve in similar ways but are pretty different in texture.

I think this would be interesting to work with for the dome given its unique form and would look beautiful with lights coming through it.  It’s important to me that it’s eco friendly.

Manufacturer / distributor info coming soon when my login gets reactive on Material Connexions.

SOFT ROBOTICS – SILICONE MOLD

I’m interested in exploring breathing texture where the top is the only part that inflates so decided to do a flat piece with this in mind. I poured the first layer of silicone thicker to achieve this effect. I cut out cardboard shapes in an abstract pattern and laid them on top of the first layer of silicone to achieve this.  I then sprayed the over the first layer of silicone and cardboard with nonstick spray. I then poured the 2nd layer, the places where you see the green shapes adhered and the negative space around it created an air channel. 

I left a pathway for air channel but when I cut it open I cut too deep, but it’s still able to inflate. I’m adding a photo of the silicone when I get to school.

Soft Robotics – Bio-Inspiration: The Axolotl

Axolotl are adorable amphibians who never transition to land because they are neotenic, or reach adulthood without metamorphosis. They are genetically very close to salamanders. They are indigenous to two lakes near Mexico City, Lake Xochimilco and Lake Chalco, with only the former remaining.

The Axolotls were revered as sacred beings by the Aztec.  The Aztec made the largest city in Pre-Columbian Americas named Tenochtitlan (current day Mexico City) on an island named Lake Texcoco. Like many plant and animal species, colonialism has directly effected their decline. In 1521, the Spanish drained lakes and built cities in its place. Currently there has been non-native fish added to Lake Xochimilco who are eating the Axolotl young.

The Axolotl have amazing regenerative qualities, and are able to regrow without any scarring, up to a 3rd of the heart, front brain, spine, limbs and testes. One can transplant leg and place it next to an arm and the body will adapt it. When they experience a severing, the cells in that area lose their individual characeteristics and act as stem cells and are able to regenerate accordingly, seemingly indefinitely.  They are 1000 more times resistant to cancer than any other animal and the only terrestrial animal that can regenerate. They are widely tested in labs due to this unique and powerful anatomy.

How its features could be used in technology: regeneration for burn victims, amputees and cancer patients. Scientists are trying to figure out how exactly their regeneration works and some believe one day it will be able to be used for human regeneration.

When speaking of stem cells or any technology in general, there is always a looming question of ethics and which directions it can go in. We are beings of light and light makes shadow,  anything we create will embody this duality and the infinite choices of what to do within that framework.  A technology like this could be used for healing or a more “unnatural” or disturbing direction.

In the 60’s, a scientist amputated n Axolotl head and transplanted it on the back of another Axolotl. Both heads continued to grow for 65 weeks until they died. In a far out, but not implausible sense, if the Axolotl’s regenerative abilities were understood to the extend that they could be put to use – one could create creatures with multiple heads or arms, or possibly combined species.
