content: Imagine that you live in a "room" which moves in a direction correspondent to your position (if you go off centre, it always moves).That is probably worse than small and round aquarium.On the other hand, you can say that you are being "fished" e.g. followed by fish.

content: This could actually prove to be useful to scientists studying fish intelligence.I think I'll apply for a government grant to buy one of these and study "Fish Responses to Various Local Stimulii Outside the Boundaries of the Aquarium"Expect my paper soon.

content: I would like to see a variation of this; an octopus in the fish tank with a joystick.

content: Hmm. It doesn't mention anything so I guess it should be assumed that this will ship with a fish pre-installed?

content: Funny that his kit includes a full Beaglebone Black. Has he not considered making a custom board for way less money?

content: Surely they could find something to replace the BB. Maybe hack one of those computer-on-a-dongle devices that I've seen for 20-ish dollars.Or make a cradle to hold an iPhone / Android device and use its onboard camera. Interface it over BT and make an application you can install on the phone.

content: Another thought, does the sloshing water not mess with the camera's ability to get an accurate fish location?If they made it so the tank part was sealed, or put it in an L shape so the fish would move in the bottom part of the L, and the sloshing would only happen in the top part, that might help.

content: I think he has it programmed to move such that it doesn't slosh around very much.

content: Quote from: Stonent on May 11, 2014, 09:54:35 pmSloshing should not be an issue for 2D location estimation (because camera is far(high) enough from the sloshing action). 3D location of fish is more difficult (if even possible) task, but they do not do/need 3D.

(In a virtual game from real world data.)"My fish is faster than your fish.""Dude, you doped your fish."http://www.popsci.com/article/science/when-one-fish-gets-drunk-its-whole-school-swims-fasterScientists, god love them, because you know, human societies and fish schools are the same!Next thing to try: Draw a Christian cross on one, a Star and crescent on another, see who they follow (if any)...When I read articles like this I always wonder, is this valid science?A side topic really, not for this thread, I just wanted to share with you this link for now.Have a nice Sunday.

content: Needs fish suicide option. If the fish performs a certain pattern, the blender starts!Nah, it's silly, just stressing the poor fish and reacting to movements that's got nothing to do with the fish's desire to move the tank.

content: I keep koi, silver perch, barramundi and rainbow trout. They all behave differently but the one thing they have in common is just about the only thing they care about is food. Given the ability to move their tank, most of my fish would follow me around the house all day because they know where the food comes from.

content: Fish care about food. I used to keep an Oscar, and had a smaller tank with feeder fish as a weekly treat. If i showed Oscar the little net he would immediately swim close by the net, then follow it down to the bottom of the tank, then back up with the snack Tilapia. Only 2 were faster than him, and lived in the tank for a few years with him until they got too big, when I returned them to the dam.
