Neural Networks for Flight Control
Something I just submitted to slashdot:
A small company called Neural Robotics has produced a robotic mini-helicopter armed with a rapid-fire shotgun. Based on their low-cost AutoCopter, the UAV uses neural network-based flight control algorithms to fly in either a self-stabilizing semi-autonomous mode controlled by a remote operator, or a fully-autonomous mode which can follow GPS waypoints. A video of the AutoCopter Gunship is available. (Dijjer mirror)
Stepping aside the ethical issues of replacing soldiers with flying shotgun-wielding robots for the moment, their “neural network-based” flight control system seemed like an interesting technical accomplishment. This PDF briefing has a few details.
Taking a look at page 14 of their PDF though, perhaps their control system is a little on the simplistic side. It seems to just update roll and pitch based on the current movement and facing of the helicopter, without making use of visual information or other sensors. I’m not too familiar with flight control, but using a neural network for that seems like overkill. When in fully-autonomous mode, I wonder if they make use of sensors for crash-avoidance at all, or if they just hope that nothing’s in the way of the chosen GPS coordinates.

1. This loan will provide the necessary capital to purchase software, marketing materials and entrepreneurial educational tool taught by master entrepreneur and CEO of Nouveau Riche University, Jim Piccolo. With the ability to now focus full-time as opposed to free-time I expect to increase my income to a respectable $1,800/month.
2. Seriously folks, this loan will be used to take my Forex Trading Strategy, which is working very well, to the next level. Look at the picture in the listing. Over 150% profit in 13 days of active, 24 hour, automated trading using my software. (Turns out never traded for real money)
3. This loan will be used to help me invest 10k into a forex managed account investment fund. I am a good candidate for this loan because I am investing my own money...
No Loss Trading Plan that really works for your.2008-01-18 20:41:56 by bfnnrgn
Are you in the Dallas, TX area? I have a trading plan that is non speculative, non directional, and generates a very high rate of return. It works everyday - all the time - with no losses - (yes) it "really" works. I have been trading the financial markets for 30 years and I understand exactly what I am doing. As a demo, I started trading a friends Forex account of just $6,000.00 on 12/20/07 and I generated a 100% return in just three weeks using leverage with no losses. Luck was not part of the success. A properly funded brokerage account will never have losses. I know it sounds unlikely but I can demonstrate and prove it "is" true. It took me most of my life to develop this technique and it did not come cheap to me. I call it my zero sum no loss trading plan and it will beat any...

$2000 for an online course huh. If it works for you. A few weeks is really good to actually begin to profit in live trading. Staying consistant over the long hual is the trick now. That takes discipline. Avoid the blowout sessions where a trader chases good money after bad trying to recoup losses. Or greedily jumps into a trade with little research.
I home schooled myself over about a year period. I didn't have the money to trade at the time so it really didn't matter. I was content to learn and save till I had it. I had some expenses that was a priority over forex. When I did have the extra cash not swallowed by life I had been profiting for over 6 months on paper and the transition to live was relatively seemless.
I'm getting nice returns now for almost a year live. From...
