This entire robotics series is unbelievably well done. Can't recall anything I've seen on YouTube that's better (and I've watched a LOT of tech tutorials).

Finding adequate power supply, regulator and following safety standards are some tricky things while building a robot. You give us some good pointers in these areas. Thanks Josh. I look forward to the next video.

thank you, i have been doing hobby robotics for a while now. Up till now i have used 2 batteries but i want to use 1 battery as my robots are small. your explanation is the first resource i have come across that is both understandable for hobbyists and sufficient in detail to give me the confidence to give this a try.

[JoshKindhart]

Thank you so much for making this video. This has been an obstacle I have faced for quite some time and it was just the thing I've been needing to get my projects off the ground!

[DPIAPU]

Excellent video! You did an amazing job at simplifying and explaining things to make it easy

Hi Josh, thank you very much for the amazing videos. Please keep on making such videos. It helps a lot. Thanks again

My robot should have exploded or be dead by now 😭 I have put it through hell without knowing anything😭 I’m holding things closed while the power is running, using leds, lidars, multiple Raz Pis, servos, dc’s, sensors, cameras! My Bot was cooking!!!! Thank you for your video and the time you put into it! I have learned so much in a short period of time and you have saved me thousands of dollars from my ignorance throwing all my investments into one robotic project without understanding power restraints and protocols! Thank you!

Great series - thank you! With respect to powering with a lipo battery such as a 3S, isn't there a danger in letting the power level in the battery drop below a certain level? Will you go into how to monitor and manage power, such as shutting things down when the battery reaches a certain level? Also, maybe how to charge a lipo safely which would be useful for a go home - roll up charging system?

Thank You For Your Time This Really Helped Me

[osielramirez]

Thank you for the video, it really cleared up some doubts I had about the cricuitry! You explained things much better than most professors lol. So far I'm starting with a Ras Pi robot kit that you can edit code for yourself, but I will be moving to making my own custom robot in the future.

❤❤❤I like your content about robotics.

So in theory with the circuit above and the motors running constantly at max the battery would run out in 30 min right?

[KingKong-kkbs]

Can I use common hardware store wires/cables for robot car powered by 12V lead acid battery? or do I need any specific wire/cables?

[nathanromany]

I can't understand the purpose of using arduino. Can you generously explain why you used it for motors while raspberry can make for you those tasks easily, too?

[TheThunderSpirit]

Hi, please suggest ways to measure the exact power consumption of robots. In my simulation, I don't have battery but I want to model the battery. I also want to model on board CPU's power consumption - which i want to optimize later. Thanks in advance.

[ericrodriguez]

If I had many sensors and a RPi and a Arduino UNO all integrated into one package using I2C would I olny need one regulator for the sensors to be powered? I know you would need a logic level converter for the RPi and UNO to communicate I am just unsure on how to let power flow through the daisy chain system the qwiic connectors can provide from the sparkfun and adafruit breakout boards.

My main issue is wiring. I want to use a LiPo battery for some 7.4v heavy duty servos with gear box, power hogs, but the servo wires as all servo wires are, small gauge, but the LiPo has larger gauge wiring, what do you use in-between them to wire reduce.

[aashrithm]

Hello! I love your videos - they are carrying my project :). I was wondering about a different battery. My rules say that electrical energy must be stored in a maximum of 8 AA batteries, and any battery using Lithium or Lead Acid is not allowed. I want to model your setup of 12v and 6A. Do you know of any recommended battery that I could use?

[CircuitMindsS]

Hey, Thanks a lot for all the info,
Keep it,

[mariadelmar]

Hi, I like your video a lot! Could you please leave the link to the regulator? I have been searching for a similar one, but it is being a bit hard. Thank you so much!!
