Jessen's icosahedron
Jessen's icosahedron
- ... that the faces of Jessen's icosahedron (pictured) all meet at right angles, even though they aren't all parallel to the coordinate axes? Source: Jessen, "Orthogonal icosahedra", [1]
- ALT1: ... that tensegrity structures based on Jessen's icosahedron (pictured) have been proposed by NASA as a "super ball bot" that could cushion space landers on other planets? Source: Agogino et al, "Super Ball Bot - Structures for Planetary Landing and Exploration" [2]; see p.22, "The six bar icosahedron tensegrity structure used as a basis for the tensegrity probe", and note that "six bar icosahedron" is another commonly used term for the Jessen's icosahedron structure in its tensegrity applications.
- ALT2: ... that the "Skwish" children's toy has the shape of Jessen's icosahedron (pictured)? Source: Cera, "Design, Control, and Motion Planning of Cable-Driven Flexible Tensegrity Robots", [3], p. 5, "six-bar or six-rod icosahedral tensegrity ... is the most ubiquitous form of tensegrity robots, in part thanks to ... children’s toys which were pervasive in the 1980’s (see ‘Skwish’ toys)"

Improved to Good Article status by David Eppstein (talk). Self-nominated at 06:11, 10 January 2022 (UTC).
@David Eppstein: Cool topic! New and long enough, within policy, QPQ done, Earwig finds no copyvios. Hook facts check out, though I think a better hook might combine elements of ALT1 and ALT2, saying that the icosahedron is used in both toys and proposed spacecraft (or perhaps robots, which are mentioned in the article). Image checks out, though I think this one is a clearer depiction. Antony–22 (talk⁄contribs) 21:09, 15 January 2022 (UTC)
- @Antony-22: I have no objection to the choice of image. How about ALT3: ... that NASA proposed a "super ball bot" to cushion space landers on other planets using the same tensegrity principles and Jessen's icosahedron shape (pictured) as the "Skwish" children's toy? —David Eppstein (talk) 21:20, 15 January 2022 (UTC)
@David Eppstein: All hooks and images check out, second image preferred. Here's a rewording of ALT3 I think is a bit more compact. Antony–22 (talk⁄contribs) 21:32, 15 January 2022 (UTC)
- ALT3b: ... that Jessen's icosahedron (pictured) has been used for both the "Skwish" children's toy and a NASA proposal for a "super ball bot" to cushion space landers on other planets?
- David Eppstein Just checking to see if you're fine with ALT3b before I promote it. SL93 (talk) 18:32, 22 January 2022 (UTC)
- Sure, precision of wording is not important for this hook, so the variation between ALT3 and ALT3b doesn't matter to me. —David Eppstein (talk) 18:48, 22 January 2022 (UTC)
