Topic: Motor control after making a turn (Read 2287 times) previous topic - next topic


Doing an unconditional state++ after the switch statement isn't going to work for all cases. Consider case 9; there's a timing condition that must be satisfied before moving on to the next state. It is a slightly unusual application of a state machine though as there's no possibility of choosing a new path through your states at run time - you could simply write it sequentially (though I can see no reason to).

It sounds like the system will simply dead reckon its way round the maze and state 11 is a means to effectively end the program by using the default case. If so, presumably case 10 will have the ball drop code added.

Fair enough. Disregard my suggestion, I hadn't thought it through. :)
Please post technical questions on the forum, not by personal message. Thanks!

More info:


the ball drop will be controlled either by a relay or by some mechanical latch or sorts, depending on the budget.

Well i reckon the movement part is done, Cheers again for the help guys, much appreciated :)

Hopefully this works on the actual robot

If you haven't tested with the actual hardware yet, might I suggest that you do so soon? You will likely discover all sorts of minor issues that'll need work.


yup were testing it this coming week
