Festo's latest biomimetic robots are a flying feathered bird and ball-bottomed helper arm

  • You could be excused for thinking that German robotics company Festo does nothing but put together fabulous prototype robots built to resemble kangaroos, jellyfish, and other living things.
  • They do in fact actually make real industrial robots, but it’s hard not to marvel at their biomimetic experiments; Case in point, the feathered BionicSwift and absurd BionicMobileAssistant motile arm.
  • Festo already has a flying bird robot — I wrote about it almost 10 years ago.
  • But the BionicSwift is more impressive than both because, in an effort to more closely resemble its avian inspiration, it flies using artificial feathers.
  • What makes a robotic hand good these days is less that it has a hundred sensors in the palm and fingers and huge motility for its thumb, but rather intelligence about what it is gripping.
  • It’s telling that the robot is transporting scarves and not plates of food or parts.

Curve Detecting Neurons

  • We found that practitioners generally had to choose between several algorithms, each with significant trade-offs such as robustness to different kinds of visual “noise” (for instance, texture), even in images much less complex than the natural images in ImageNet. For instance, this answer on StackOverflow claims “The problem [of curve detection], in general, is a very challenging one and, except for toy examples, there are no good solutions.” Additionally, many classical curve detection algorithms are too slow to run in real-time, or require often intractable amounts of memory..
  • Images that cause curve detectors to activate weakly, such as edges or angles, are a natural extension of the algorithm that InceptionV1 uses to implement curve detection.
  • Every time we use feature visualization to make curve neurons fire as strongly as possible we get images of curves, even when we explicitly incentivize the creation of different kinds of images using a diversity term.
