Okay, The first one was okay, but in six weeks, I have to go to the West Point military academy and compete in four more events, one being Sumo Bots. "We can rebuild him, we have the technology" Construction for Labotimize begins today, Pics up tomorow, hopefully the La-bot-amy videos will be up tomorow also
RULES (more or less)
Wiegh under 2.5 Kg
voltage must not exceed 18 volts
robotmust fit in 30cm x 30 cm square
must operate on at least 3 frequencies (we have 7 sets of crystals)
CONSTRUCTION IS FINISHED!!!! ITS AWSOME! Okay, so this bot will be used in the Mightybot Challenge and in the Science Olympiad Sumo Bot event in Westpoint New york in march, Today when we fired it up, we pushed 5 KILOS!!!!! THE BOT WIEGHS 1.6 kilos! so efficiency is about %320 efficiency I will post Pictures tomorow and a video link also. I'm pretty excited with this guy
Okay, states is over, final weight of bot...2.2 kilos, wieght pushed 11.2 lbs (5 kilos), so 119% efficient, poop
Motor driver/ controller How are you going to switch frequencies with the sabertooth? To wire a motor from that thing one would just ignore the signal wire and wire - and + right?
we are using a futaba No, we are using a futaba reciever (R132JE AM 27 MHz), we will feed the two channel outputs to the sabertooths channel 1 and 2 inputs, how else are we going to controll it?
oops Whoops, I forgot to look at the sabertooth documentation. I thought that there was a receiver built in for some reason. I was thinking of building a battlebot, where did you get your reciever and transmitter?
well, they were on sale at a The sabertooth is pretty pulg n play huh? well, they were on sale at a local r/c shop (dans crafts n things) for 40 bucks paired, if you want one theres one here, it comes with the transmitter, reciever, 2 servos, and a battery pack
sabertooth Yeah, The saber tooth looks very easy to use. No complex motor drivers to make or anything,really. It looks awesome. And I think I may bid on that ebay auction
Your sumo bot should weigh Your sumo bot should weigh basically 2.5kg, no point in having a lighter robot to win a draw if you flat out lose in the first place. Some pics would be great.
When we first tested it, we When we first tested it, we stalled it, and loaded down the controller, we needed to cool it to allow it to drive 10A and higher almost continuously for 2 minutes at a time(the length of the match)
ok, now i understand, 10A is frigging lot of current The drivers I am using in my current project would propably melt ( they get pretty warm with just 2,2 A)
the funny thing is that the the funny thing is that the Gearboxes on the motors alone weigh more than the batteries, our center of gravity is actually just behind the forward most point on the wheels. Our problem during the competition was the scoop didnt stay on the ground if we accelerated too quickly, this problem caused us to loose our final match to a bot that ws fast enough to get under us before the scoop came down!
