Well yesterday, after four long years, I got to open up about the robot I built and it made me realize just how many design changes I went through to get the final product. Technically it’s not even the “final” product, it’s just where I stopped and the next person took over. There’s still a lot of work left to be done with the design, but looking through all the photos of the process, I realized just how much work that robot really was.(more…)
A wild collaborator appears!
It seems like weird stuff just keeps happening left and right lately! Yesterday out of the blue I heard from a collaborator I worked with from the UK. It’s been months since we last spoke and he had some personal issues due to COVID, so I wasn’t actually sure I would hear from him again.(more…)
Artificial muscle for soft robotics: Low voltage, high hopes
Soft robots do a lot of things well but they’re not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store.
3-D printing aids in understanding food enjoyment
Tasting food relies on food volatiles moving from the back of the mouth to the nasal cavity, but researchers have wondered why airflow doesn’t carry them in the other direction, into the lungs. Now a team of engineers, using a 3D printed model of the human airway from nostril to trachea, has determined that the shape of the airway preferentially transfers volatiles to the nasal cavity and allows humans to enjoy the smell of good food.
Study finds metal foams capable of shielding X-rays, gamma rays, neutron radiation
Research from North Carolina State University shows that lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding means the metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.
