Hm...zanimivo. katere kontrolerje uporabljaš?

Poslikam in pošljem, hvala 👍

Maybe next year. With RTK

Hi! if you have 12V starter you could power it from middle terminal of 2 batteries connected in series. That way you will get 12V. Just connect it through high current relay. Since this relay is switched off most of the time, it should not affect the battery charge balance. Anyway if you afraid that one battery will not be fully charged you can buy battery balancer. My next video will be about battery balancer since many people have this issue. Hope I helped. www.amazon.de/-/en/dp/B07SRSCCX2?ref=ppx_yo2ov_dt_b_product_details&th=1

I made electronics for driving main motors and control board for start/stop gasoline engine, turn on/off lights, horn, etc... Actually will not take much to prepare all kit together. Thanks, good proposal.

Hi, thanks for comments. I am thinking about making basic KIT to start from.

I suggest you play with ramping a little bit. It smooth the motor mowement. Recommend!

@gregorkobetic do you use the P1 and P2 for anything? I did check voltage and it's 3.3 - 3.5v using a 12v power source. Now I know I can dump the 9v plug in to arduino and run from one of those. I'm not fam8liar with ramping but I'll check in to it more

Hi, glad to heat that. Could you provide link to web page? Thanks

Some gasoline engines have generator for charging batteries for electric starter and to power lights, etc... however this power is in range of about 100W. My motors together need about 700W

@@gregorkobetic Thank you! Has the alternator some rpm works limit? I mean, my alternator has a 2.3in pulley while the gasoline engine crankshaft has a 6.3in pulley, witch means that, when the gasoline engine be working on 3000 rpm, the alternator will on 8700 rpm

@@diegoContodo my alternator can go over 10000, I can remember exact number. I think you are in safe range. But anyway check datasheet of your alternator 😉

Hi, that is custom electronics that I developed for remote control lawn mower, since many people have asked me for help in that field

Živjo, alternator sem sam dodal, da mi ni potrebno polniti baterij. 24v 90A, kar je sicer ogromno rezerve, lahko bi bil manjši.

Thank you

@@gregorkobetic всегда пожалуйста бро. Желаю тебе успеха и процветания в этом деле!!

​@@gregorkobeticr u building motor drivers from 0?

@@obuchalki yes, from zero. The one that you see in short video is universal electronic for rc lawn mowers. It have 10 relays for switching different devices like lights, motor engine starter, mowing hight, safety, etc and to drive main dc motors.

​@@gregorkobetic​ that cool. I do not have such knowledge to build motor driver from scratch. Would be great to see some tutorials

Živjo. Kakšne motorje boš uporabil?

@@gregorkobetic 4x 250w 75rpm

Predlagam, da vzameš sabertooth 2x60. S sabertoothom 2x32 so lahko problemi pri obračanju na mestu, ker se začne vklapljat tokovna omejitev. Doma imam še en prototip elektronike z releji in kontroler za motorje (rešitev vse v enem). Če te zanima mi napiši na mail gkobetic@gmail.com.

Živjo, v sloveniji se ga ne da kupit, običajno se dobi na amazonu, ebayu ali robotshop.com. Fajn je, da ga vzameš znotraj EU, drugače sledi navrh še ddv in nad 150€ še carina. Doma imam en kontroler za 2 dc motorja skupaj z 10 releji, ki se krmili preko rc receiverja prav za kosilnice. Če te zanima, mi piši na mail.

Hola! I recommend cytron drivers. You can replace sabertooth 2x32 with cytron mdds30, here is the link www.google.com/amp/s/www.cytron.io/p-30amp-7v-35v-smartdrive-dc-motor-driver-2-channels Hope I helped, have a nice day. Saludos to Mexico

Hi, 24V 55A alternator are available for good price. You have to dimension alternator with extra power, becouse motors take more current then declared if they stall. If you can get 12v motors you can get 12v alternator for lower price. But remember less voltage take more current for the same amount of power.

Hi Dragan, thanks for the nice comment. I don't think this camera have brand name. It is 24MP camera with 130x optical zoom from china. I'm happy with it. The only thing missing is autofocus, which is usually found on more expensive cameras. I bought it here: www.amazon.de/gp/product/B0CBMRV7BR/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Thank you!

Hi, sorry I am not shure if I understand this right. Your rpm is 1260/145=8.7? For 25cm wheel you need 75rpm to go 3km/h. Your robot will be too slow. What are you trying to build?

i was using a micro esc found on a micro servo and off the market micro esc to control the bts 7960 instead of a relay. it did run sometimes and sometimes it doesn't.🥲

my pleasure ;)

I bought it on anazon.de www.amazon.de/-/en/Rovtop-Independent-Positives-Negative-Indicator/dp/B08ZKNP3JR/ref=sr_1_6?crid=175DZYRLU5F70&dib=eyJ2IjoiMSJ9.Kt3bRw8nN2meHMwikILtFAfoNHjiY4d0XNnQKEdfn7VQ8_3sbj211ZCzT-JgE4ilcwK4GI7B5gD05E3USsDCagEZszBLsCUIpQbBJi7eXDrumEfwZgmFzbY6wI8WfrMnVYCyjxcBddWl8Jpc9ch3i_o7cYTAczQDp14IZThyVCRj2xvkaMAFE2jAiy-YGv3VI8Yve6_SKBfyuHmi_82St4IWh9xtxzwqlJa52o-jxjcSejTjMmCR47unE4bpFLnsZSFOWvPFBHThCcRD44UFoE5TWBLuVOApVn2WYcrJLzo.nopJEfwVZMr9YUhhaS9pWyTXxnW-3DpyzJjvJC7xS8Q&dib_tag=se&keywords=fuse%2Bbox%2B6&qid=1710352677&sprefix=fuse%2Bbox%2B6%2Caps%2C260&sr=8-6&th=1

thanks for this info@@gregorkobetic

Tole je Sachs and Vettel motor narejen v osemdesetih, dvotakten. Za kosilnico cca 100kg bodo 250w motorji ok tudi za v strmine.

This is my second account

Sorry didnt understand your question. Could you explain a little bit, thanks

I dont have experiance with pixhawk, but what I have seen from manual, every motor controller with rc sgnal or pwm signal input should do the job. Look for sabertooth or cytron motor controller

Hello, It's basically very easy. One channel from the RC receiver you connect to the Cytron controller and then where the electric motor is usually connected, you connect the actuator. Do you have a more specific problem? What are you worried about? I don't speak Spanish so I use google translate as well :)

The problem I have is that I use the 2 channels of the MDDS30A for the 2 MY1016Z3 motors to drive forward, backward and both sides and the linear actuator only has 2 positive and negative cables, can I connect it to the relay that you told me to turn on the lights? It is a 12v 30w 3 Ah linear actuator. Can I use the relay to turn on the lights to make the linear actuator extend its entire distance, which is 10cm, or even stop before it extends its entire length and then retract inwards? Is one relay enough or should I buy 2, one to extend the length of the actuator and another to change the current so that the linear actuator retracts? Sorry if I didn't explain myself well, next time I'll try to be clearer! I really appreciate your help, I built it to help my father in the field. I am a professional driver. I had a serious accident and my back is broken. I can no longer do international work.@@gregorkobetic

No problem, it's easy. Buy this relays from the link below and connect it to a channel where you have three position switch or joystick, so that you can move the actuator out, in and stop. drive.google.com/open?id=13Fb0eEKkRRdKi0nUl82udXW9trxm3iGB&usp=drive_fs

Thank you very much, you are my teacher in this, I still don't know how to do so many things that I would like to do with the robot apart from making it autonomous haha Well now we're going to the countryside, a big hug from Valencia Spain@@gregorkobetic

Thanks, I try my best to give something to community

Hi, I can't imagine what you could do wrong to blew up the motor. Are you shure it wasnt just faulty motor?

Hi, you need usb cable. Thats all. Works like a charm.

@@gregorkobetic thank you - seems i missing something - where and how it should be attached? Could you make quick video - i think many looking for same information - that would be very handy.

forgot to mention i have 2x60 - does it also suits?

Uh, 2x60 don't have usb port. You need usb to TTL serial cable like this: www.dimensionengineering.com/appnotes/Roborealm/Roborealm.htm S1 is Tx and S2 is Rx I am sorry I don't have sabertooth 2x60, so I can not make video about it.

@@gregorkobetic - that's was what i looked for - many thanks for helping out!

Hi, that's great if it works in your case! According to the BTS7960 datasheet, the chip has an operating voltage between 5.5V and 27.5V. The chip limit is just above 28V, so if it works, it is just on the limit. Alternator is usually charging at 28V.

It looks realy nice. Very well made. Congrats on sucessfull project!

Thanks, wish you all the best with your project 😀

Hi, you can not attach relays to RC receiver directly. You need some sort of controller to handle the rc signal and control relays. For higher slopes you must have 4WD or tracks. If you dont have high slopes you are fine with 2WD and better wheels. Brushless motors are better because they have constant torque and no brushess, however motor contollers for brushelss motor are more expensive

@@gregorkobetic you can easily attach a relay to a receiver - what makes you think you can’t?

@@janramonmartin you can if you use relays for Rc receiver. What you can not do is connect standard relay that you can buy in every electronic shop. Thats all am I saying. Have a nice day!

I am not shure if I am qualified to answer this question, but long time ago I checked this possibilitie, and I remember that hydraulic motor were very expensive. Not shure how are prices in China now.

Buy this board to control relay with rc receiver: www.ebay.com/itm/155205293795?hash=item2422f4d6e3:g:c0cAAOSwxXRjRlf8&amdata=enc%3AAQAIAAAA4ORO2AVx4YtMWvkCMNquwnfTa8aUpxH2AVJPlxW%2BvMeHGokuDj%2FoLumUdd8fWqc6mvJuFVEFCu9a%2Ba85cWQK9oqN4hf%2BFybNfAaR9Rncat%2BJG9m1LlU%2FtqS3%2Fm4wkU0%2FTv%2B69LQzvEOAliHP0o7l0og9yG6gQe8x7ifOFB3%2B2InOBVz2I04K88h%2BI92j4FOFbCZKHuXvUS1nTWvTrRKfET8CRVfYiPTEEFhEBIi4q6S%2BiwRXHZq3sDjdQ02bmW%2Bwf4IHaex5PxIG8QhMEoSyfbq13oOkYzgeLNS%2BU82NJ9p6%7Ctkp%3ABFBMqIL7vadj Then connect any lights you want over this relay board and you are done.
