Clutter, angled thrusters and debugging

[Denis]

I am starting to make circuits to make my robot "do stuff" and I'm not very fancy yet, but already the robot's interior is very cluttered. Half of the clutter is due to the fact that thrusters aren't angled, so the option to have them angled (aligned with the isometric grid) would be a good thing (it's on the list, I know. I hope bumpers will align with the thrusters as well?).

I'm wondering if we can manage to get really fancy in the limted space. I know there will be circuits eventually to help with this, but I'm not sure how far off they are. From the BOM for circuit A I think they're still far off for me. I haven't all the gate seeds yet and I think circuits are for the phase where you are planting gate trees.

Also regarding getting fancy: it's really hard to debug fancy circuit. There is the clutter, and then things are happening too fast (when the logic gets into play at least) to really see what's happening. I can't see why my circuit does not always do the same thing.

The key to cleaning up the clutter, is not Curcuits (A and B), it is Chips. That is where you get to wrap up your circuitry and make it all disappear from the robot interior.

As for things happening to fast. Yep. The gate propagation clock is about a third of a second (maybe less) while you are watching, and faster when you close the robot.

One of the tricks is using a 1-shot to make things happen 1 step at a time. Here is one way to make it.



Every time you apply power to the NODE...the output of the AND gate, goes high for 1 clock cycle, then it goes low again.
You have to remove power and apply it again to get it to cycle again.

This makes it easy to move 1 step at a time. Apply the output of the AND gate to the thrusters that move in the direction you want to go, and then you can easily walk 1 step at a time, without having to play the power button game.

Here is one of my *Magic Circuits* that I use in my robots.




The 4 pins on the left side are connected to the thrusters. The two lower pin on the right determine the direction to move.
There are 4 combinations of input, and they correspond to the 4 directions of the game grid.

X Y Direction
0 0 SW
1 0 SE
0 1 NW
1 1 NE

There are other ways to arrange the logic, but this one is easy for me to remember.

I use external logic to determine when to move, and how far. (see the 1-Shot circuit for an example)

Not circuit but chips: ok. Of course this means that it's much further in the future than I thought since chips require circuit A and circuit B and probe and electronic tools, etc. The road to get there seems long...

Thanks for all the tips rkda! I'll come back and check all of this when I get my first chip.

2 other quick things:

Thing 1: Take a quick look at the one-shot circuit. It works because of gate-delay. Without gate delay, you wouldn't be able to make that circuit.

Thing 2: If you tap a gate in your robot, it will rotate 90°. When you solder, the wire starts horizontally, then angles vertically to meet the 2nd connection. You can use these two things to organize your circuit a bit.

Also note: Some have argued that the space "in the middle" is too big, and thrusters/bumpers should all be closer together for easier soldering. I'm pretty sure that would only exasperate the clutter problem. That said, also "On The List!" is: you can move the robot parts around to anywhere you want. That's much-later, but I recognize that different people have different ideas, and so I don't see why not to do that. Eventually.

[Denis]

Thing 1: yes. Of course, if there was no gate-delay, we wouldn't need to slow down the circuit to debug it. (it's ok, I embrace gate-delay, but your argument is circular and I just wanted to point that out)

Thing 2: yes, I got all that. It does help.

Space in the middle: Actually when things started to clutter, my reaction was to ask you to move stuff further apart. My reaction was actually "hey why is everything cramped in the middle instead of spread around the edges?!"

See, THIS is exactly why the end-result solution will be to allow individual players to drag around their robot-interiors however they like.

Heck, maybe I'll get fancy and let people save "interior designs", so they can switch. (Once there's a layout that's saved/restored with the farm, there's no reason not to allow multiple layouts be saved/restored, right? )
