In this video I talk about dc motors and recommended speed. At the end of video we calculate wheel diameter and speed of lawnmower.
Speed calculator:
docs.google.com/spreadsheets/...
Motor 24V 350W 330rpm

You can also control the max speed of your mower by adjusting a few setting in the transmitters EXPO setting area. By adjusting the rate of input around the center of the joystick you can reduce the max value of the stick input as well as slowing down the reaction of input for accurate slow speed control. I used motors from a Jazzy mobility chair and the 13 inch diameter wheels that chair came with. I also use a sabertooth 32A dual speed controller set up in mixed mode. With the Expo setting adjusted I have a very controllable mower.

Excellent video. It sure will inspire me to continue working on my lawnmower. Btw, on one of my projects I use the same motors, power full and cheap! I'm looking forward to see more of your videos.

Great video. Can you suggest a motor driver for MY1016ZL motor which is compatible for pixhawk.

@gregorkobetic 3 месяца назад

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

@ronzika335 5 месяцев назад

Thanks as usual. Are you going to eventually move it into Ardupilot?

@gregorkobetic 5 месяцев назад

Hi, yes I am thinking about it for long time. It is hell of the project. I have to sort things out theoretically first, becouse I am a little bit confused when looking ardupilot hardware. I am not shure which hardware is compatible and cost effective. Did you make any progress?

@milanmedic4053 3 месяца назад

Little help. I have 4 motors with this specs: Supply voltage: 24V Rated current 1.4A Rotational speed: 1260 rpm Gear: 145 Would all four be enough to start and have enough power to wriggle through the grass?

@gregorkobetic 3 месяца назад

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?

4:46 je to tomo vinkovič srk 70 kosilnica ? trenutno tudi jaz predelujemo to kosilnico na električni pogon z dvemi 250 w motorji. bo to dovolj za pogon v strmine ?

@gregorkobetic 3 месяца назад

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

@kgkg5849 3 месяца назад

Hi, do you have the reference for all terrain wheel ? Please

@gregorkobetic 3 месяца назад

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

Rather than use arduino why not attach relays direct to your RC receiver? Do you think you could have just used the wheelchair motors with better tyres instead of tracks? I notice the newer Chinese Rc mowers are using much better brushless motors and differentials to power their tracks now

@gregorkobetic 5 месяцев назад

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

@janramonmartin 4 месяца назад

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

@gregorkobetic 4 месяца назад

@@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!

Hi, The tracked version is very cool but more expensive. Here's my version for 4x4 with chains and two chain tensioners on each side. It weighs about 120KG and works great: How it turns : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZF2rqSu_Dxs.html Drive train in detail : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7DUQMMLatK8.html I did have a lot of problems in soft soil with the drive train because of the weight before the two chain tensioners on each side.

*Where is it cheaper to use a hydraulic motor with a magnetic motor boss?*

@gregorkobetic 5 месяцев назад

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.
