Good evening Ryan,
Thank you for the link,
I will order the two engines in order to test.
I will come back to you for advice on programming.
Best regards
Question, the power going into the pixhawk POWER port.
You say 12v is going into it, can it handle 12v going in? I thought it was 5v max input?
@@IeuanBevan. It's been too long to remember, I would refer you to the ardurover manual!
Thanks Ryan
I will test today
I'm currently doing a similar setup and i'm stuck on the parameter settings in Mission Planner. Can you share your settings and possibly a wiring diagram for this system. I'm missing something, I can't get the motors to run properly
Sorry for the late reply. This video might be helpful - sorry it's so boring! ruclips.net/video/V67tA-PdVOQ/видео.html
Good day. Is it possible to connect Pixhawk 2.4.8 Controller and sabertooth 2x12 motor driver for Rover with one battery?
I will assume you either built an autonomous rover and/or a boat
When you pair the RC; the pixhawk domain, and the motors together, do you have to calibrate it?
For example, building an UAV that uses PixHawk and connects to the mission planner firmware, you need to calibrate it by Tilting it in different angles with the mission planner
Do you have to do that in your project??
Hello Ryan Moeller !.
Can I connect my Cytron MDDS30A too?
My station is FlySky FS iA6X with its 10-channel receiver the FS iA10B
I use 2 MY1016Z3 24v 350w brushed motors
Can I use the Pixhawk to make my robot autonomous? The MDDS30A is almost identical in operation to your Sabertooth Dual
Please help me, advise me what I need to do to convert my robot to autonomous?
Yes the pixhawk can definitely make your robot autonomous. See this manual here: ardupilot.org/rover/
One question. What if you wanna take your rover backward. how do you do that?
Great presentation
Nice video.
Nice! Where can I find this type of motor hub? How it is called? Thanks!
The microcontroller is a Pixhawk and the motor controller is a Sabertooth Dual 12A
is it possible if i use L293 or L298 motor driver for my rover using pixhawk controller? i cant find sabaertooth dual 12A Motor driver in my country
In the final design, did you use a seperate battery for the Pixhawk? Also if you don't mind, I'm curious which motors you decided to go with?
Yes I used a separate, LiPo 3s battery for the pixhawk. The motors I went with were IG42 24VDC 078 RPM Gear Motor from Super Droid Robots. They were slow but had plenty of torque and then some.
That's incredible!!! I've been flying rc's for many years and I've recently decided to build an APM Rover. I'm doing research on parts and pieces and your video is exactly what I was looking for. Thank you for that!!! Have you progressed with your robot any?
I'm glad this helped! The robot is all finished and I'm hoping to find time to make a video soon!
@@ryanmoeller6892 im looking forward to seeing any of your progress!
gr8 work . if I can ask how did you setup a model for a Frysky, I have a 9XD plus but there is no model for a rover? (2 DC wheelchair motors controlled by pixhawk 4, robocla3 2x30A, Qgroundcontrol and S-XSR frysky receiver)
To set up my model I just followed the instructions that came with the receiver. This video is a little rough around the edges but might help: ruclips.net/video/V67tA-PdVOQ/видео.html
Why didn't you use the PWM signal from the X4R?
I'm currently trying to connect an x4r receiver to the sabertooth dual with 12 Volts. I tried to use the PWM Signal coming from the X4R Receiver, but the sabertooth somehow does not like it. But PWM should work, shouldn't it?
Yes PWM does work on the sabertooth. You have to set the switches on the sabertooth to the correct positions, though. You can find the information on which positions the switches need to be in by reading the sabertooth manual. (I got the manual from here where I bought it from: www.superdroidrobots.com/shop/item.aspx/sabertooth-dual-12a-motor-driver/1155/) I used mode two, RC mode.
When the X4R is connected directly to the motor controller you can use the X4R channel pins, one pin per channel.
When the X4R is connected to the pixhawk you have to use the sbus pin because the pixhawk only has one input pin (RCIN) so unless you're only using one channel on the X4R you have to use sbus. I hope this helped.
Hey there! Great setup. I have played around with APM myself. Now looking to get a Pixhawk to experiment with.
I was wondering, wouldn't it be better to put both motor channels into 1&2 and enable mixing? In other words, forward, backward and direction all on the right stick? I have done a similar setup with the same motor controller your using setup for mixing. This way you have full direction and acceleration control on one stick. Of course, if this is the way you want it to operate then this suggestion is mute.
I did this at first, but then I found that when I was turning in one direction and trying to move forward slightly, my finger would accidentally move the stick in the reverse direction and then back to the forward direction very rapidly. This would cause a lot of strain on the motors as they switched from forward to reverse and back. So i seperated the throttle and the turning so this wouldn't happen. Thinking about it now, I could have just adjusted the parameter for turning speed so that the wheels weren't at full speed when the stick was tilted all the to the left. Did that make sense haha!? You're right though, either way would work. I'll be using this mostly in auto mode so it doesn't affect things too much anyways.
@@ryanmoeller6892 I had experimented with using two sticks early on. But as my projects started using more channels I found it convenient to pile steering, direction and speed control on to just the right stick. Leaving the other stick free for other things. This idea was further advanced when I started building custom Pan/Tilt rigs for my event video side business. The right stick in those cases took care of pan/tilt with full speed control. While the left stick as well as other channel pots on the transmitter where free to use for zoom, focus and iris control. Record stop/start, etc. I just purchased a 6wd wild thumper chassis and am hoping to use the left stick to alternate between pan/tilt of a camera and other functions like an arm/gripper or turret control.
So basically for me, consolidating motion control to one stick was out of a need to free up controls/channels for other things. Grouping them together for easy access. But what ever works, eh. ;) Good stuff all around. Again, good job!
As for intergrating the PixHawk, I would like to make it a part time autonomous setup. One where I can remotely cut out automatic control to switch to manual when needed using the stick configuration I described.
Dear Sir,
What's the difference between this version and Radiolink version?
hi ı have a btc7960b and ı want wire like you please help me they have 8 pin ı need just one what should use ?
I'm sorry, I'm not familiar enough with your setup to understand the question. Best of luck.
👋hello ryan
It's been two days since I finished the connection and I have a problem.
I looked for, I made several modifications without positive result.
my problem: I have the forward and reverse command on track 1
but I don't have a track 3 direction.
my configuration:
2 motors connected to Sabertooth 12A
a Pixhawk + Mission Planer
FlySky FS-i10 2.4g radio + FS_iA10B receiver
* do you have to mix in the radio?
second problem:
mission planer denies me the auto function.
I have 1 = manual
in 2 = RTL
in 3 = auto >>>> error on glider mission.
thank you for your help if possible
Best regards
Disclaimer: it's been awhile but yes you mix the signals in the transmitter. Sounds like you need to add a channel for left/right using the controller. Make sure the mixing settings are the same in both the transmitter and the pixhawk.
At about 27 minutes there's a section that might be helpful. This was intended to be a boring but on depth explanation so that's what it is haha: ruclips.net/video/V67tA-PdVOQ/видео.html
awesome!
Can you please make a video for pixhawk 4 full collection
This video is a little rough around the edges but I hope it helps! ruclips.net/video/V67tA-PdVOQ/видео.html
Is that a kangaroo on the desk? Did you get it to work?
Not exactly sure what you're referring to but I didn't use a Kangaroo on this build.
hello, sir, I have the same setup as you,
can you plz tell me the Sabertooth dip switches layout that you use.
Hello! I used the Sabertooth documentation and some trial/error but you can see the layout at 2:08 (ruclips.net/video/4-KvA8BWleA/видео.html). I wrote them down for you here: (disclaimer, the video was fuzzy so these might be backwards! I am not currently able to look at the robot itself so this is the best I can do.)

hello ryan,
can you give me the link to order the motors
Regards
www.superdroidrobots.com/mechanical-parts/Gear-Motors/42mm-Gear-Motors/product=491
That whole website is awesome, they even have instructional pages that are amazing. Give it a look.
One last reply: that gear ratio I used was meant for a robot in muddy fields, i.e. high torque low speed. If you want to drive a light robot on paved roads that are mostly flat you will want a different motor with less gearing. They have a lot of gear ratios to choose from which is nice. They also have a web page for how to calculate robot speed if you don't already know.
Hello
Version firmware rover??
Thank you
Hello have you any experience on Ardurover? Thanks
This is my first time using ardurover, and I have learned a lot but I'm not an expert.
Thanks for your feedback Ryan. Could I know your e-mail? I had started to assembly the Rover but I have still few doubts...Regards
@@andreacecchetto5748 I'm not keen to putting my email address in a RUclips comment for anyone to see. But I'd be happy to answer any specific questions you have via comments.
What’s the function of GPS in this demo 😂😂
Is there an update?
Yeah I'll probably do an update when I am done. I'm still working on robot chassis and RTK GPS stuff. Anything specific you'd like to know? I just posted this so that my professor could see my progress but if you have a specific question that I can answer I'd be happy to help.
