Pangolin-inspired robot can dig and “poop” out seeds to plant trees

Posted on by

Not all robots have to look, well, robotic. There is a growing number of robots that are inspired by real life creatures (sometimes, even humans, but that’s a whole other discussion) or so called bio-inspired bots. The latest winner of the Natural Robotics Contest is inspired by a pretty unlikely animal: the insect-eating mammal called the Pangolin.

Designer: Dorothy and Dr. Robert Siddall

A high school student from California named Dorothy designed a robot whose main goal is to dig and plant seeds. Since pangolins are naturally digging animals, why not use it to create a robot that can help populate areas with more trees? The winning concept was turned into an actual prototype called the Plantolin by the partner research institute. More than just looking like a pangolin, it uses features from the mammal and incorporate it into the functions of the robot.

The Plantolin roves around on two wheels and just like the pangolin, it balances on its long, movable tail. Each of the wheels has an electric quadcopter drone motor. The digging is done by these two front legs with the tail tilting down once it starts to provide leverage. Once there’s a hole already, the robot drives over it and poops out a yew tree seed bomb nugget (containing both seeds and soil).

It’s a pretty interesting way to re-populate a space with more trees. It will probably be faster and will need minimal human intervention when it’s programmed right, so no need to train actual pangolins to do the job.

Crayons from Japan’s recycled trees highlights the country’s forests

Posted on by

When you think of wood, the color that immediately comes to mind is brown since that’s what most of us have seen in the trees near our abodes or even when we travel. But it’s not the only color that we can extract from it, specifically from various species of forest trees. With 2//3 of Japan covered with trees and a lot of these forests remaining unharvested and unmaintained, it’s interesting to see what sustainable products can be made out of these trees.

Forest Crayons is a project that uses the pigments extracted from various recycled forest trees and mixes them with other sustainable ingredients to turn them into crayons. Each one has a different shade that is based on the species of the recycled tree as well as how it was cultivated and grown. For example, you get a light green color for magnolia and a deep turquoise of fungus stained wood.

The pigments extracted are mixed with wood, rice wax, and rice oil to produce the different crayons. There are ten crayons available in the Forest Crayons set: Bayberry, Bogwood, Cedar, Chinaberry, Cybress, Hazenoki, Katsura, Kaizuka, Magnolia, and Zelkova. Some names should be familiar to most people but there are species that are native to Japan and some that have Japanese names.

Forest Crayons are actually supported by the Japanese Forest Agency and aside from producing these from recycled trees, they also want to “breathe new life into Japanese wood” so that people will have a new appreciation for the country’s forests. I would prefer the triangular shape of the crayons shown in the product shots but it makes sense of course to have them in the traditional crayon shape for functional reasons.
