Diddiborg with Ultraborg over Web UI

The distances shown in the web UI in that code are divided by 10, so they display as cm.
The values in the code are in mm, so they need to be 10 times larger.
e.g.

will be for distances below 15 cm as shown on the web UI.

The code you have shown for the auto mode has a couple of coding mistakes that will cause it to not work:

• One of the lines is missing the final ).
• You need to use elif for each additional condition, else is only used to mean "anything that is not covered by any if or elif above".
• All of the conditions set the same speed: 30%.
  I guess you were trying to make him stop when too close.

You can simply the code a bit by only doing the maxPower calculation and the setting of the motors once.
This is because each time you want to set the motors, the only difference is the speed you are setting.

I think something like this would do what you were intending:

I think the reason the code is slow to react to changes is due to the onboard filtering performed by the UltraBorg.

UltraBorg has two modes for reading ditances:

1. Filtered:
   Cleans up the distance readings to give better accuracy and stability.
   The filtered readings update slowly, they may take up to 2 seconds to change to a new value.
   Used by calling the UB.GetDistanceX() functions.
2. Unfiltered / raw:
   Provides the latest reading from the sensor without any filtering.
   These raw readings update quickly, but they suffer from 'noise' and may be less accurate for measuring a fixed distance.
   Used by calling the UB.GetRawDistanceX() functions.

I would suggest replacing UB.GetDistance1() and UB.GetDistance2() with UB.GetRawDistance1() and UB.GetRawDistance2() and see if the response is faster.

What you could do is make another couple of global variables for the users set speeds.
You can then do some simple tests to see what direction the DiddyBorg is set to move in.

Here are the basic bits to get a "direction" value which you can compare to presets:

That is a good idea :)

It should be fairly easy to put that code into the diddyWeb.py script.
I think the simplest way would be to add these blocks of code:

At the bottom of the import list:

Before the "Timeout thread" code:

And add the highlighted lines to the section "Stream delegation loop" which is run each time an image is taken:

Adding the button code to metalJoy.py is fairly simple:

1. Add the imports to the import list at the top
2. Add the pin setup above the "Setup pygame ..." section
3. Add the highlighted lines to the "loop indefinitely" section:
   

   1 2 3 4 5 6 7 8 9

   # Loop indefinitely     while running:         # Check for button press         if (GPIO.input(buttonPin1)):            #this is the script that will be called (as root)            os.system("sudo shutdown-h now")         # Get the latest events from the system         hadEvent = False         events = pygame.event.get()

That line needs to be further to the right than the if line above it.

Put simply Python is sensitive to the use of tabs or spaces at the start of the line.
The error you are seeing is telling you it expected a line to start to the right of a line above.

You could use either, but I would suggest a push to make would be best.

You should wire it with a weak pull-down resistor like this:

Use a nice large value like 10 KΩ for R1, Vcc will be the 3V3 pin.

That is the basic idea, yes.

The only thing is that you want a large value resistor.
A larger value means less wasted power when the switch is on.
Too low and you might exceed the 50 mA maximum for the 3.3v pin.

For the resistor I would use at least 1 KΩ, which would use 3.3 mA when turned on.
Ideally something like 10 KΩ would be better, that would use 0.33 mA when turned on.

This might be a problem cause by your text editor :)

Programming languages are very picky about the character symbols used in code.
In particular the quoting marks for Python and HTML need to be of the " or ' type.

At the moment you have:
httpText += ' iframe.src = ”/Lightoff";\n'
and
httpText += ' iframe.src = ”/Lighton;\n’
for example which look like the text editor has swapped some of the quotes and double-quotes with the fancier style ones.

What you wanted to have was:
httpText += ' iframe.src = "/Lightoff";\n'
and
httpText += ' iframe.src = "/Lighton";\n'

The symbols you want to use are: " '
The ones you want to watch out for are: “ ‟ ‘ ‛
These are often used by editors such as Word to make you text look nicer.

There are a fair number of lines with these rouge symbols, and they can be quite hard to spot.
I would suggest either using the find tool on your editor if it has one, otherwise turning the font size up helps a lot.
In the section of code you posted there appear to be bad quote symbols on lines: 101, 105, 200, 204, 240, 242.
