Picture of 6-Wheeled R/C Wheelbarrow with Pneumatic Dump

This project started out life going to be an r/c lawnmower. It has now morphed into this six wheeled creation.

Step 1: UPDATE! PLEASE SEE VIDEO BELOW. THANK YOU.

Step 2: Robot: Materials & Tools

Materials: Electric wheelchair (from EBay, Craig'™s List, Pawn Shop, or steal your grandmother'™s), motor speed controller (from on-line vender like www.robotmarketplace.com, R/C radio transmitter, r/c receiver, mini high torque servo, (from on-line or local hobby shop). Tools: Assorted wrench set, assorted screwdriver set (flat & Phillips head), Allen wrench set (SAE & Metric), wire cutters, wire strippers. Optional: Battery power screwdriver, electric tape, 14AWG wire (if necessary to extend wheelchair battery leads). (NOTE: these instructions are contingence on the make and model of your wheelchair).

Your the man! I have been looking for a week or so for something like this. I have plans for a trail version of your project. I like mining/prospecting and I like the woods. The one thing I don't like is listening to is motors in the woods. Similar to a Power Wagon, this will be a great drive system for my Electric Mule Cart for packing my gear into the woods. Sweet..

Great idea. I was thinking about a similar power base to serve as a RC tractor that could use a variation of a fifth wheel coupler to attach to implements like a lawn mower, (reel, electric, or gas) snow blower, garden cart, leaf rake, sprayer, garden cultivator, etc. lots of potential uses! Thanks

Automated wheelbarrow, handheld dump truck, what's not to love? :D

I think this is great. I don't know how easy it would get around rough terrain and tight spaces but it looks handy. Was there a capacity limit on the lift?

Just wondering along with michael. Less accuracy in unloading and much more lift power required this way.

Really nice build !! I agree with your design. Having the dump backwards allows for a FULL & COMPLETE dump...does it not? The dump will be a wider, less specific dump but how often does anyone need a very precise dump? Maybe you can update your answer above if you have tried it and let us know exactly what happened.  My only other observation about the design is "Why pneumatic"? Seems like high speed electric would reduce the time and cost of  the build. Using deep cycle batteries should overcome the electrical energy loss. Anyway, I was just wondering if you had considered this lift method and dismissed it for a reason? Again, "Thank You" for a great idea and good instructions.

Very clever, excellent ideas especially the two wheeled wheel barrow, Keep up the good work...................................................JG

To the questions on the bucket/barrow. You can't tell from the pictures but the angle of the "scooped" end is such that it is almost parallel with the ground when the cylinder is in the vertical position. To design the cylinder to extend much past the vertical position would not be good on the cylinder. Also, the "flat" side does have a slight angle to it so material will slide out. As for volume, it's the same either way. In using a wheelbarrow you must tilt the wheelbarrow off the leg assemblies to roll it where you want to go. Here the bucket stays level the entire time until you dump it. Video to come when work allows me time to get back to the project. I already have several modifications I want to make to the prototype. Updates and video coming. Thanks for looking!

You know what would be a really spectacular next step? Give it some AI control, and operate it by voice commands or possibly use a Kinect-like sensor for arm gestures. Since a wheelbarrow-robot has a somewhat narrow functionality it wouldn't need a very large command vocabulary: "Follow", "Stop", and "Dump" should suffice. A command for returning to its charger could also be handy.

Wow...good ible .. interesting solutions..
Just a question.. Why turn the barrow round the other way?
Regards..

I'm with bullgog69er, show us that cool trike you're building in the background. Nice dumper.

Why is it backwards? Seems like a waste of volume/capacity.
duggerpato11 months ago
Awesome! But the wheelbarrow is backwards, bud.
carneage11 months ago
why do you have the barrow working backwards? it will not hold as much material or pour as well from a low long square edge rather than a tapered rounded edge.

Is there a reason that it's designed to dump backwards?

Awesome! Now you just need a video of it in action...

I built a remote roboyic lawn mower out of power chiar too using vex contralor and vector 833 speed controls electric start motor one of thease days ill post pics of it u did a nice job trike in back ground looks nice too

Awesome build, I'm working on a r/c project for a theatre and am curious what motor speed controller you used.
edvanhal11 months ago
I am impressed. I purchased a cordless electric wheelbarrow and it's OK but it needs more power... I am interested in the dumping action, because it can't be tipped manually (too heavy?). Way to go!

This thing is so ridiculous, yet so fantastic. Next, build an RC shovel, haha. That way you don't have to do any work.
