Hello, i was watching some of your guys videos and i really like your guys robot, i was trying to make a robot just like yours, but when i started testing it, the battery was getting like, drained, i was using 6 li-on battery, u guys have any ideia of the motive of it?
note: i was just using the raspberry pi b3, and arduino nano and two dc motor(6v)

[@evbrobocup]

We use 2x 18650 lipo batteries in series (so around 7.4V). For powering the Raspberry Pi as well as our servo motors,, we make use of two FEICHAO UBECs that output 5V. Our Pololu DC motors are powered by 12V via two U3V70F12 Step Up Modules.
Edit (to accommodate your edit, I leave the old answer for others): So your batteries drain faster than you expect? Are they relatively new and of a trustworthy company or did you charge/discharge them a few hundred times? Another cause could be that the batteries were stored under suboptimal conditions (completely discharged, completely charged, extreme cold...) for a long time. Last but not least, the rapidly draining batteries could be caused by a faulty circuit design, have you checked the power consumption using a multimeter?

​@@evbrobocupHello, thank you so much for answering the question, we used old laptops batteries, maybe this could be the problem, and we didnt test the batteries consumption on a multimeter, again, thank you so much for answering, now i'm going to try getting some new batteries, any Idea of a good local to buy It? 😊

[@evbrobocup]

We got ours online from Samsung, but there are dozens of tests online on which batteries to buy

@@evbrobocup Ok, thank you for the informations, wish you guys good results in 2024 :D

Ich verstehe die neue Rescue Zone mit den neuen Ecken nicht ganz. Gibt es dafür irgendwo ein neues Regelwerk?

[@evbrobocup]

Ja, sind die offiziellen Regeln von 2023. Rescue Kit und silberne Kugel müssen in grün, schwarze Kugel in rot

[@psynox]

@@evbrobocup aha danke! Aber was passiert wenn man die schwarze Kugel auch in grün tut ?

[@evbrobocup]

Nichts, aber gibt dann einfach keine Punkte. Wart ihr dieses Jahr auch in Kassel?

[@psynox]

@@evbrobocup ja wir sind dort 7. geworden

Hello, I'm from Brazil and I participate in the same competition as you guys but I'm having some difficulties as it's my first time and my school never had it either, if by chance you could help me I'd be very grateful, I'm going to participate in the reginal in 1 month and I use the ev3 for my robot, if you could give me some robot design tips with lego and programming and s block it would help me a lot, if you want to talk send me a message
