Hackaday Prize Entry: Octo, The Robotic Walker

Posted on by

Walkers like the Strandbeest are favorites due in part to their smooth design and fluid motion, but [Leandro] is going a slightly different way with Octo, an octopodal platform for exploring rough terrain. Octo is based on the Klann linkage which was developed in 1994 and intended to act as an alternative to wheels because of its ability to deal with rough terrain. [Leandro] made a small proof of concept out of soldered brass and liked the results. The next version will be larger, made out of aluminum and steel, and capable of carrying a payload.

The Strandbeest and Octo …read more

[Hari] Prints an Awesome Spider Robot

Posted on by

Although we have strong suspicions that the model’s designer failed entomology, this spider robot is very cool. [Hari Wiguna] made one, and is justifiably thrilled with the results. (Watch his summary on YouTube embedded below.)

Thanks to [Regis Hsu]’s nice design, all [Hari] had to do was order a hexapod’s dozen 9g servos for around $20, print out the parts, attach an Arduino clone, and he was done. We really like the cutouts in the printed parts that nicely fit the servo horns. [Hari] says the calibration procedure is a snap; you run a sketch that sets all the servos …read more

Giant Spider Roams The Streets

Posted on by

There is a giant spider the size of  a house stretching its massive, delicate legs as it parades through the French city of Nantes. Is the Arthropod Apocalypse upon us? Fortunately not, for this arachnid is the latest in a series of performance pieces by a French theatre company, La Machine.

Like the rest of La Machine’s productions, this spider is a large hydraulically controlled model driven not by a computer with a single operator but by a team of operators perched inside and underneath the mechanism who turn the operation of the spider’s legs into a piece of complex …read more

Fail of the Week: Arachno∙fail∙ia

Posted on by

Going down the list (FCC, CE, UL, etc.) we can’t think of a regulating body that will test for this failure mode. Reportedly, a $1M irrigation system was taken down by a spider. And an itsy-bitsy spider at that.

This fail turned up as a quick image post over on /r/mildlyinteresting but I wasn’t the only electronics person attracted like a moth to a flame. Our friend [Sprite_TM] popped in to answer a question about conformal coating. Seems this board was sealed in a waterproof enclosure but was obviously not conformally coated.

[Sprite_TM] also helped out with some armchair-engineering to …read more
