    Chris, you always take me back to my school days of robots and BBC Micros in these videos, and I thank you greatly for that.
    As great as modern tech is, the idea that we can move a robot with a computer seems as fresh now as it was over 40 years ago and with your delivery, doubly so.
    Top stuff indeed!

    This is precisely the kind of thing that I enjoy most! I tried to get an RPi RP2040, but was forced to settle for a board with the RP2040 included. The Cytron Maker Pi RP2040 includes 2 motor relays and 7 discrete 4-pin Grove connectors. So far it has been a disappointment, but that's likely because this is so different from using Python via GPIO on a Zero W or other CPU packing RPi.
    It would interest me to see the Maker Pi board run through its paces in your most capable hands as I am without much joy using the board so far.
    Perhaps you could repeat today's exercise using the Maker Pi RP2040? The whole smash cost me $12 and it will do as I require ... eventually!

    Hello Chris,
    That's an amazing project because of simplicity and practicality reasons,
    I'm sure that you know all what I'm about to say but just to let others know that there is always a space for improvement as you mentioned in the video,
    Regarding the html code, you can actually use one form element (without specifying it's action) and then set required formaction on the submit buttons,
    also, instead of send the html in each response, you can send it only when the request is empty,
    and to prevent the page from reloading after submit you cam specify a target where the response will be delivered to, so it may look like this





    anyways, it will not make it faster but it may save a few bytes in the response,
    If it's up to me I'll use XHR or WebSocket API for faster response time
    Sorry for the long post but I just get excited 😁
    Thanks once again Chris and have a nice week!

    Considering how much the Raspberry Pi is used in education, perhaps this is something that you could focus on in order to increase your viewership. Because this is a very fun little project, and immediately usable for students. The two main issues there is that students are usually not very rich - so likely wouldn't become Patreons - and that Raspberry Pis (Pies?) are nigh impossible to find at the moment.

    That looks like fun. I'd be interested to hear if you could calibrate it so that you could have buttons for different amounts of turn. For example 'turn 90 degrees left'. I guess you'd need to use that ratio for the motors to work out how long a full turn took as a starting point. Or maybe you could implement variable speed control to the motors.

    • @ExplainingComputers
      @ExplainingComputers  2 ปีที่แล้ว +7

      Hi Graham. What you ask could be done in two ways. The simple way, as you say, would be to run the motors for a certain length of time -- using sleep command -- having worked out/experimented to get the right length of time. And this would basically work, although it would not be that accurate, as the time would change when the batteries wear down, the tracks could slip, etc.
      A more sophisticated solution would be to work out the number of motor rotations required, and to fit encoders on the motors so that this could be monitored. If you look at the CU shots of the motors, you will see the shaft extends out of the back, which can allow an encoder to be fitted to measure their actual rotation. So the motors would be run in a loop that would terminate when the number of rotations for a 90 degree turn was reached.

      @@ExplainingComputers - Why would it not work? Each _def move_forward()_ etc. could just include move_stop() at the top before setting each output bit for the H bridge driver. While technically not needed (as you show) it might be easier on the motors not to slam from forward to backwards especially if you included a small delay after each move_stop(). Right turn, stop for 0.5 seconds, left turn. The bigger the robot or motor, the more important it would be to allow it to stop before changing directions. When driving a car most of us come to a stop before slamming the car into reverse... although it would be fun to watch otherwise. ;-)

      @ElmerFuddGun Yes, certainly it would work to include the command to prevent potential damage to larger motors as you describe. But that is not what the comment I responded to is about! :) It suggested that it would remove the need to press "stop" between moves, which is not necessary.

    Importing 2 variables for your wifi, is not for when the device gets stolen, just for video publication (no need for blurring),
    it also prevents having to change your daily wifi password that may be embedded in various other wifi devices.
    also some wifi routers have guest network options (+active hours), i would use those.
    Or make the pico W an access point

Suggestions: underfacing edge sensors, when the gamma value changes, stop. How about a small arm that folds and extends, and then the real challenge! A camera on the arm to detect beverages through ML, grab them and return them to the own, like a beer-bot or say cola-bot? 😆

      Technically, it is most certainly in a robot. A robot is mechanical device under programmatic control, and this is exactly what is going on here. The motors do not respond to controls (as in an ROV), but to a program in turn operated by controls -- which here is an ROV program! :) There seems to be a lot of confusion about what the term "robot" means these days. :)

      @@ExplainingComputers The limit is really thin between them. A quadcopter like a DJI one with all the complex behaviours embedded in it or remote controlled by pushing only a button is surely called a drone or a flying robot.
      But a program that translate/transmit simple orders/inputs like a remote control to a vehicule, can it be called a robot ? It remembers me my philosophy courses back in the day. We had only 4 hours left to try to answer this question and I never succeeded. :D
