MagneBike - Magnetic Wheeled Robot

 

The MagneBike is an interesting magnetic robot that is surprisingly flexible and can maneuver some crazy metal geometries.

“Locomotion Concept and Robot Design

  • Two wheels in a motorbike arrangement: better adaptation to the surface (flat or curved).
  • Magnetic wheel unit including lateral lifter/stabilizer arms. The lifter functionality helps to pass over step obstacles. The stabilizer functionality allows to drive sideway.
  • Five active DoF: front/rear wheel, front/rear lifter, steering unit.”

Electron Microscope Image Capture with an Oscilloscope

at 2:06 pm. Filed under Computer Hacks, Insane Equipment

 

What to do after you get your hands on a discarded scanning electron microscope. Ben Krasnow from Applied Science took the signal directly out of the device and fed it into a DSO. He was then able to capture it at a much higher resolution than is displayed on the original CRT that came with the unit. The results are incredible.

3D Printed Car

3D Printed Car

 

Printing this car took just 44 hours our out of 44 parts. Just bolt on some electronics and wheels are you are ready to drive! Love the design but up close it doesn’t look polished like a metal vehicle but you can see that it goes together in thick levels. What will we see in the future? Instead of customizing your new car by picking a color, interior trim option and accessories are we going to be able to push and pull some of the body features? It sure does open things up for some interesting thoughts.

Fast Charging Batteries that last 20 Years?

 Fast Charging Batteries that last 20 Years

 

Apple is famous for making nice looking products that are practically sealed for life even though many of us consider the internal battery a serviceable part. Having to access batteries for occasional replacement might be a thing of the past. Also planning to charge items is currently something that revolves around many things, you probably plan to charge your phone while you sleep, your electric car gets topped up when you are at work, you have a few sets of batteries for your cordless power tools. Wouldn’t it be nice it charging took a few minutes instead of many hours? How about a battery that lasts 20 years, which is typically more than the entire usable life of the device? This might not be science fiction for much longer. Scientists at Nanyang Technology University have developed fast charging batteries that can be recharged up to 70 per cent in only two minutes!

Thanks for the tip John.

“In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide.

Titanium dioxide is an abundant, cheap and safe material found in soil. It is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays.

Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. This speeds up the chemical reactions taking place in the new battery, allowing for superfast charging.”

U.S. Navy Autonomous Swarm Robot Boat

U.S. Navy Autonomous Swarm Robot Boat

 

The U.S. Navy is developing Autonomous Swarm Robot Boats. These boats are outfitted with Control Architecture for Robotic Agent Command and Sensing (CARACaS), this technology was developed by NASA for the Mars rover. 

“Navy researchers installed the system on regular 7-foot and 11-foot boats and put them through a series of exercises designed to test behaviors such as escort and swarming attack. The boats escorted a manned Navy ship before breaking off to encircle a vessel acting as a possible intruder. The five autonomous boats then formed a protective line between the intruder and the ship they were protecting.”

Fostex FE206En Back-Loaded Horn Loudspeakers

Check out this crazy internal baffle structure of this cool Fostex FE206En Back-Loaded Horn Loudspeaker.

 “The back-loaded or rear-loaded horn loudspeaker system is like bass-reflex and double bass-reflex speaker types in that the sound radiated from the back of speaker transducer is utilized to enhance the bass response. The difference however is that back-loaded horn (BLH) speaker enclosures make among the most efficient use of the back wave from the speaker driver. The back-loaded horn speaker enclosure operates by developing the bass response using the back wave from the speaker driver and an expanding horn section. The remainder of sound spectrum (mid and high-frequency ranges) is radiated directly from the front wave produced by the speaker driver. Back-loaded horn speaker enclosures are generally amongst the most efficient enclosure systems and respond well to the subtlest components of music signals. For “tighter” sound reproduction, you can reduce the interior volume of the horn speaker cabinet using fill material. Sound absorbing material should be used directly behind the driver and also at the mouth of the horn to smooth out the frequency response.”
