More important?

I not think you have many problems of timing, and engine are controlled by MPU hardware interrupts and if the code is simple minimally there will lag

RE: !!! HOT B-BOT PROJECT UPDATES & UPGRADES !!!
Okay. But i decide me to IR Sensor, it is easyer to put it into the Maincode without changing much Parameters or Calculations.

In this Winter my B-Bot will run at Home in Autonomus Mode. Time is very rare.

I will hold anybody UP 2 Date Wink

Greetings Wampo

RE: !!! HOT B-BOT PROJECT UPDATES & UPGRADES !!!
HC-SR04 sensor work fine. My servo output was unused because my robot rise up without arm, so, I put sensor on servo and it stay horizontally all time and not affected by robot swing. I make Autobrake function - if you run robot fast, it make very nice looking brake with drift turn at 180 degrees and themselves stopped 10-15cm from wall. If you run robot at moderate speed it stop without turn and drift.
BUT (!) - sensor work fine ONLY in large room without furniture. There is lot of problems if you run fast in room with tables chairs etc. Robot time after time detect distance for break start and it stay jerky, it break or decrease speed time after time and you can't normally drive. You can change detecting distance shorter, but then it will not be able stop at high speed. Also sensor can't detect distance from angled surfaces - if you drive to wall at 45 degrees it cant see it Sad You can put sensor on another servo (horizontal moving) or even put 3 or 5 sensors, but anyway problems in room with furniture. There must be complicated code for recognizing small/tall objects or angled surfaces when robot turning and driving fast, but Leonardo have only 32kB flash memory Sad Now I have erased code for HC-SR04 sensor and voice/sound Wtv020sd16p because I need more space for driving code

Hi Sasa.

So many treads and messages. While I start create my BROBOT without the brain-board and surely I wanna use sonar detector for self-driving mode.

Do you have any experience with that ? Any good forum's link where I can find all information to build BROBOT on Arduino+ESP or straight on ESP ?

I am good in Arduino programming, so no problem for me.

I tried sonar sensor, but at final I removed it. Robot can't drive fast in room with tables, chairs etc, it brake very often. Much more fun is fast driving with manual control. You can look at KomX code for esp8266+sonar.

I will have a look on KomX, thanks.

I understood you. How the hell is it stopping in front of the wall? just crashing to it ?
I plan to mount mobile phone on the robot, but that it will be easily damaged Huh

Ok, it's time to realize the little robot-balancing!
I have all the material to make it happen but I ask the wiring diagram of the light led version and the last updated code,
thank you to those who want to help me,
Yours sincerely,

Which LED light desire? Briefly describe your vision of functionality.

Goodmorning everyone!
forgive me if I answer only now, I have a very busy time.
I love that illuminates the different color LEDs according to 'action of the robot.
Also I would like to build the robot a bit higher ... nopn know if you can do it?
