Remote Control Garden Wagon

Post by Wrench » Fri Jan 05, 2018 4:06 pm

Does anyone know the proper materials needed (shopping list style) to create a remote control garden wagon, i.e. childs radio flyer style wagon? I have fabrication abilities with metal and wood, but RC eludes me. Also, if you know of a more appropriate blog to ask such questions then I am happy to take note.

Essentially, I would like to drive loads of garden material around and/or drive my son around in the wagon via remote control. So the wagon would need to carry up to say ~150 pounds, give or take, and the top speed could be anywhere from 4 to 14 mph, give or take.

I considered this blog because I don't want to reinvent the wheel and I assume many people on this blog have already build similar (and much greater) things; I'm looking for some guidance from the experienced and knowledgeable folks who peruse these blogs.

I had considered attaching the axle from a two-wheeled PAW (power assisted wheelbarrow) to the rear of a wagon but I don't know what kind of servo could handle steering the wagon (1/5 scale, or maybe a linear actuater??), and I am not sure I could get a speed controller to handle the 26 amp peak draw on this 24 volt PAW axle...

Any advice is welcome.

It's basically a scaled-up mobile robot. Use two drive wheels and then you can implement skid steering. For a speed controller, look into wheelchair speed controls, or this: https://www.robotshop.com/en/cytron-30a ... river.html

The https://www.4qd.co.uk/knowledgebase/ site used to have tons of information on speed controls and quite a few circuits if you want to DIY, but I haven't been there in a long time.

For other sites that are more into this, you can check out the Machine Builders network, but it's a pretty slow site. Could take weeks for an answer: http://kramerville.net/mbn/ubbthreads.php?ubb=cfrm

Lyndon, thanks for the further resources. I will check them out. To date, I have decided to merely attach a servo to the actual throttle of the wheelbarrow and use a linear actuator for steering. Not the most elegant solution, but the K.I.S.S. principle applies to most of my efforts. Thank you again for the resources.
