06:32 Jak_o_Shadows not xfce
06:40 deshipu unity
06:40 jthornton I havn't tried unity...
06:58 Vetaxili Hi all, I'm supposed to implement EKF based on Thrun's "Probabilistic Robotics" books without even understanding the math behind it. :-S I was doing ok so far but I got to the stage where I have no clue what one variable is supposed to be, namely Q on line 100.Would anyone be able to help me out please? http://pastebin.com/7dghx3j6
07:04 chris_99 unity always seems to screw up for me
08:07 jthornton well I did finally figure out how to sort out the "panel" in xfce and now it is nicer
08:26 Vetaxili how can I generate occupancy map 'manually', i.e. without using matlab's package?
09:05 killa_ I am trying to control my bot using arduino and xbee on transmitter and receiver side but unfortunately i cannot establish any sucessful results
09:05 killa_ i use iteadstudio xbee shield
09:05 killa_ and s2 xbee radios
12:24 deshipu phew, moving home is a horrible thing
12:25 deshipu I'm left with just the bed and luggage
12:33 veverak :D
12:42 deshipu oh my god
12:42 deshipu they glued a tiny cannon to a cocroach
12:42 deshipu to measure how its gait changes when there is a sideways force
13:18 deshipu also, using jelly as a force sensor for measuring the cocroach gait
13:18 deshipu turns out orange jelly is the best, because they don't eat it as fast
13:19 chris_99 haha
20:06 rue_house hah
20:06 mrtnj ha
20:08 Tom_itx haha
20:20 Anniepoo I've made robot parts from gelatin before
20:20 Anniepoo gummy bear bots!
20:20 mrtnj how did that work out?
20:21 Anniepoo pretty decent
20:21 mrtnj what was it able to do?
20:21 Anniepoo I was looking for something rubbery and skin like for a social robot
20:21 Anniepoo silicone's expensive
20:22 Anniepoo I worried it'd degrade over time, but it's still pretty much the same as it was
20:22 mrtnj lol nice. are there any videos of it around? sounds like an interesting project.
20:23 Anniepoo hmm... you know, I don't think I've got anything
20:23 Anniepoo I never made a whole robot with it - I just cast some test pieces
20:23 Anniepoo but now I'm tempted!
20:23 mrtnj an edible robot!!
20:24 Anniepoo yah, I kept doing tests of the tear strength by nibbling at it
20:24 mrtnj delicious project to work on too thens.
20:25 Anniepoo now you've got me started, darn it!
20:25 Anniepoo lol -
20:25 mrtnj i just recently got into robotics, but i haven't made anything yet :\
20:25 Anniepoo I've got some semi-hefty servos
20:25 Anniepoo maybe I could make a worm bot with gelatin skin
20:25 niepoo thinks about how to cast a
20:26 Anniepoo face is the obvious thing to do
20:26 Anniepoo maybe pour it into a halloween mask
20:26 mrtnj gummy face?
20:26 Anniepoo need to mix is fairly soft for that
20:27 Anniepoo you can adjust the hardness
20:27 mrtnj how autonomous are your robots?
20:27 Anniepoo gummy bears and those soft lifesavers gummys are really soft
20:27 Anniepoo but jujubees are really hard
20:27 Anniepoo but they're the same stuff
20:28 Anniepoo depends on which one you're talking about
20:29 mrtnj how autonomous was your most autonomous robot?
20:29 mrtnj can you tell me about it?
20:29 Anniepoo I used to work for robokind - theirs are relatively autonomous
20:29 Anniepoo http://robokindrobots.com/
20:29 rue_house my robot is so autonomous, its whats typing to you now
20:30 Anniepoo well, my most autonomous robots were virtual robots - I used to work in virtual worlds
20:31 Anniepoo anyway, I'm headed for supper
20:32 mrtnj enjoy!
20:33 mrtnj robokind seems to have a meaningful goal.
21:40 mrtnj buh bye!
23:25 theBear hehe bear bots
23:25 theBear hehe, bear bots
23:26 theBear woopsie doozy
