#Dev log 1.0: Its a Thing Now!
Well its defintitly been a while since i posted a dev log and I have actually been working on the robot in that time-shockingly productive for me. I have
-printed all motor cages, top plate, bottom plate, and battery plate. So I dont think ill need to print anything else
-I have started programing the controller, using potentiometers to send values over the ESP-NOW protocol to the esp-32 on the rover itself.
-I have all the physical parts besides the wheels because of Amazon issues

It doesnt feel like much after writing it down but thanks to me doing most of these things for the first time, everyyy step was full of of issues and time spent (def more than what was logged) trouble shooting.

Anyways simply put, I have the robot, now the boring part, codinggggggggggg
Things I have to work on include:
-controling all arm servos with the controller
-Figuring out how to move the TT motors that run the wheels
-Figuring out which wheels need to turn to go each direction, which is a bit trickier with mecanum Wheels
-Use joystick for controlling wheels, and I’ve never coded a joystick before yayyyy
-Once the controller stuff is all ready, solder it to a PCB (breadboard)

Here he is, every thing but his wheels. The battery is stored under the bottom plate and the motor drivers and esp-32 sit in between the plates.
Feel free to give me advice as always, and thanks for reading.

This log is mostly for me to figure out how to use stardance and how everything works (I spent like 20 mins figuring out how to go to a new line) anyhow here is what I’ve done

  • I’ve gotten the general shape down and, as I write this, am printing a test fit to see if I will move forward with the design.
  • I am kind of going with a more framey design, with almost as little material as possible
  • I’ve learned how to program servos on a ESP-32 for the first time and have successfully actuated every servo on the robotic arm
  • Spent an embarrassing amount of time figuring out how to use one of the two motor drivers ill have to use to run the wheels and their respective hobby motors. The only way I’ve gotten it to work is to send 5V to the 12V terminal.

The next thing I plan on working on is the remote control for which I plan to use another ESP-32. I should note that I have never made something remote controlled, so fingers crossed on that.

I think that sums up every thing I have done, if you have any tips on anything please to let me know as my technique in robotics is best described at “fumbling around till it works”.
Thanks for Reading!!!!!!!
