Nope. The power supply was stiff and well filtered, and separate for both the motors and
Did you manage to calculate the total power budget for your circuit? Switching relays take up a lot of current as well.
By well filtered I hope you did add 0.1uf ceramic caps in close proximity to the Vcc and Gnd pins of your logic chips. Tantalum (not electrolytic) 4.7uF along the power rails. Oscillators should be well ground and the clock lines as close to the clock pin on the processor as possible.
And how about the ban on Half-life a while back. It was said that a parent who was an MOE (ministry of education) official complained to a LAN shop onwer that blamed the shop his son was playing too much computer games. The owner then said it was the parent's fault and not his, and led to a squabble. The parent left by saying that he would pull his weight and get half-life banned! Eventually it did get banned, but after reaction from the gaming community here (thank goodness for the internet here) the ban got lifted after a few weeks.
So much for government impartiality.
One of the reasons why titanium is not used except in specialised cases is not only the cost, but it's workability using hand tools.
If you've ever done custom cases you would not the DISTINCT difference between working with steel and working with aluminium. Now picture the difference between Titanium and steel.
I did a project in high school (~1985) trying to use a ZX81 as a controller for a robot. It worked, kinda. Very susceptible to emi, especially the sort that small DC motors put off. It used technology that was "good" for the time, which translated to today's technology, means "slow and power hungry."
EMI? That's sort of unlikely for stuff running at low speeds and for circuits of that size. More likely it's a power supply problem.

Sane thing to do, would be to test it out on those crash dummy thingies first.
Monitor temp, forces etc... You don't want to get your hands ripped off by the winds...
Anyone notice that at the mission control centre?
