Hi very nice rover. I am also currently building one. as a platform I also have a children quad. at the moment I am dealing with the question of how you have solved the control of the linear drive for the steering. Can you tell me how you solved that from the pixhawk?
Hi. Awesome robot! I've got the same one. b.t.w. If you take that lame 24v engine motor, and bolt it to the steering shaft with a servo drive, you can get all the power & speed to steer it without using that slow wheelchair-ramp actuator. You can use a cheap brushless R/C airplane motor with a $15.00 reversible esc - and you'll be able to launch wheelie's with it.
Erich Stein I'm not sure I understand what you're describing. The Leeson 1/2 HP motor produced over 35mph @36v with different sprockets using a Vyper controller. Ended up bringing it back to 24v w/ a Syren50 and gear ratio @6:1 as the wheelbase is just too short and it keeps flipping at anything over 15mph. Incredible torque now and ideal for autonomous missions.
I'm sorry, this was my ignorant mistake. The "LAME" 24v razor scootor motor, I was talking about. I can now see the the LEESON motor you are using, looks impressive! I found the same motor 24v, 17.5 lbs-torque @ 20 amps.
Awesome! Thanks so much for the specific answer. I am currently building one of these vehicles for my graduate thesis project. My goal is to make something people can experience. Your project is inspiring! How did you interface the actuator with the pixhawk? Thanks.
Please share it's making video
Pretty awesome chassis design. More off-road!
Hi would you be able to share some details on the new motor. Looks like it has plenty of power. Currently looking for a motor for my bot. Cheers

I think He used an old servo pcb and a linear Poti so its like a Standard servo control
Nice !

Erich Stein Faster steering not needed. @140lbs, strength and reliability with an actuator.
Yes, your right. It's not like it's easily possible to make this actually go fast.

Is that frame from a golf-caddy?
Negative. Frame is a Razor Dirt Quad.
What kind of linear actuator did you use? Cool build!
Jeremy Bass Thanks! Firgelli 12v 200lb 2" feedback rod linear actuator. 2yrs and still working well.

I´d love to know that too!
I had the same spam "your Angelica"...I'm very sad to discover that I'm not her only love :-)
