Linux-Based Robot To Explore The Forest 84

Posted by timothy from the sasquatch-is-running-scared dept.
crashoverride025 contributes this link to a BBC story about Treebot, "A Linux-based mobile robot equipped with a webcam and sensors swings into action to help monitor forests." Despite the Tarzan reference, it looks like this robot moves along a cable, rather than swinging from place to place.

    what we all agreed before...

    probes sent to mars should've been run by linux. Instead of worrying us to no end, now we would be discussing the data obtained and ways of improving the performance of futere missions.

    Not only that, I'm sure that the code for those probes beeing opensource would've meant people contributing and finding solutions and apps no one would've thought of...

    Wouldn't it be lovely that the routines of a mission to space would've been a truly world project, with programmers from all over the world taking part in it?

      Are you kidding? what do you think they run, Windows?

      Linux is great, but nowhere near the level of certification required for software that runs on space probes. The latter, as well as software running on airplane computers, space shuttles, etc ... are so strictly checked that many parts of them are proven mathematically, with great care, at great expenses.

      Just propose NASA or ESA to power their stuff with Linux and they'll probably look at you with a thin smile and the kind of condescending look one makes while shooing a slightly annoying retarded child.

I work for a company that produces GPS guidance/navigation systems for planes/helicopters and our systems use Ms-Dos 6.22, no joke.

        • Using Linux in any way you choose is not restricted by the GPL.

          Restrictions based on agreement with the licensing conditions of the GPL are limited to the manner by which YOU offer code up for distribution.

          So if NASA chooses not to distribute their copy of the code, how are they in violation of the GPL?

          (I admit I'm not sure how, in this case, distribution within an organization might be regarded by the FSF law team.)
          • Where does the organization end, an another begin? NASA is a good place to examine this murky, yet fundamental, factor of the GPL. Can the GSFC [nasa.gov] use it internally, without triggering the distribution clauses? All of NASA? The US Federal Government? US Citizens? The American People?

    helps by being stealthy enough to travel through the forest canopy along specially-constructed cabling

    I suppose a piece of metal crashing through tree branches hanging from a cable is more stealthy than, say a jackhammer. Wouldn't it be more quiet if many sensors were placed about the forest and used wifi to connect and send information? They could even still run linux to do so and get mentioned on slashdot!

    • I know it's a far stretch, but it's entirely possible that the team placing the cables might have, umm, you know, actually looked at the area while they worked. I know it's a bit of a challange for a college student to be able to identify branches, let alone avoid them while stringing the cables; but that's why they have advisors.

      As far as placing other sensors...well, if you had read a little bit farther in the article:

    As the article says, the treebot is part of a "Networked Infomechanical System", a type of wireless sensor network [crcpress.com], developed by the UCLA Center for Embedded Networked Sensing [ucla.edu]. The forest network [ucla.edu] is used to develop practical wireless sensing technology while simultaneously providing an example of its utility. The use of a mobile network node in a wireless sensor network requires some engineering of the multihop message routing protocol, since such networks are usually assumed to have stationary nodes. I don't know what they've done to address this; it could be anything from MANET [navy.mil]-style routing (e.g., AODV [ucsb.edu], in which they accept the resulting increase in route establishment overhead), to a quasi-static approach in which the treebot reassociates to the network every time it stops.
