Doug,

The code is in MATLAB and uses one of their ordinary
differential equation (ODE) solvers "ode23".  I can send
code if you wish.

Data for the on-target curve is provided below.

Doug,

I did that several years ago and posted to this group.
I will see if I can can find the code/results.

Maybe, but not for a while. One step at a time. I’m not 100% sure the Challenge 
is do-able by garage quality robotics (and garage quality funding).

 

I found some differential equations describing paintball trajectory that 
include lift and drag. I need Tracy’s advice to help me translate them into 
code that will compute the marker elevation based on a target distance. The 
math is hanging me up. She’s pretty booked up with school, though.

 

I think it will be interesting to see how close the equations come to correctly 
describing the flight. I may be better off with some experimentally obtained 
lookup table of range vs. elevation.

 

I’d love to win the Challenge and make Frank donate the $1000 to Hillary 
Clinton’s campaign :)

Sorry, but there are no secret settings that can be controlled from the game

Hello –

 

I’m getting Bad Kitty ready for next weekend and I see it’s developed an

compensate. I know I can do this via the serial interface, but I’d have to

hard to program the device while checking the turret for correct centering. 

 

Is there a way to set the trim from the PS2 controller directly ? Like 
double-secret set of magic button presses or something ?

[TANKS] C12C question

2015-05-31 Thread Doug Conn
Hello -

 

I'm getting Bad Kitty ready for next weekend and I see it's developed an
involuntary turret rotate condition. I suspect my turret ESC is going bad.
Until I replace it, I wonder if I can adjust the trim of the controller to
compensate. I know I can do this via the serial interface, but I'd have to
disassemble part of the tank to get access to the C12C. Even then it would
be hard to program the device while checking the turret for correct
centering. 

 

Is there a way to set the trim from the PS2 controller directly ? Like
double-secret set of magic button presses or something ?

 

Thanks,

Doug
