  2. In other news. local slug population iq has been swelling with introduction of new predator, thought the culprit hasn't been identified…

  5. "These gearboxes seem to have self-healing capabilities…"
    More like 'natural lubrication' capabilities… blerghs

    I'm also impressive with how resilient that little thing is, and also with the fact that it wasn't being kidnapped in all that time.

  6. I believe you should put two more wheels on the solar rover and put two motors powering each wheel. Also power the trailer with two motors. Please do this, i think this will make the solar rover much, much better. If you do this in the next video, i will be very very very happy.

  8. Been enjoying so much your videos! I decided to start learning electronics and bought the Arduino kit. Do you think learning Arduino is a right step to get into this awesome world? …oh, and should I go CR 10 Smart or Prusa Mini + …Thanks .

  9. Kinda wondering, do you have any permission to run the rover there? I mean from the land owner. The GPS accident may have been caused by an angry human being

  14. 3:28 Tannins in the grass is probably lubricating the cogs. That stuff can cause a train to skid on the tracks as if it was ice. Usually happens when driving/braking on leaves.

  15. Watching your channel has made me really start to consider going back to school for robotics/mech engineering. This is just so damn awesome. Nice work man!

  16. CAN YOU MAKE A FULL SIZE ONE YOU CAN DRIVE!!!ELECTRIC CAR WITH SOLAR PANELS ALL OVER IT AND WIND TURBINES ON THE ROOF AND HOOK UP ALTERNATORS TO THE WHEELS SO THE CAR CAN RUN CONTINUOUSLY FOREVER THE CAR WILL ACTUALLY CHARGE ITSELF WHILE IT ON THE MOVE WOULDN'T THAT BE AWESOME?!!!!!!!!!!!!!!!! CAN YOU BUILD ONE? I BET YOU CAN!!! PROVE ME WRONG!!

  20. The slugs are probably attracted to the vibrations the rover makes.

    A pretty cost-effective and convenient lubricant nonetheless.

  23. I am loving the rover project, may I suggest a water blaster or sprayer near/in gear box to wash bio mass out when needed?

  25. I think it would be wiser to simply separate the gearbox from the wheel, to basically only have one point of entrance for debris to get into the gearbox, to increase it's maximum expected lifetime, and having that single point of entrance be as high above the ground as possible. For example, you could have the connection point connect to the wheel on the top of the wheel, on the highest point it can connect to the wheel in the current configuration, which would allow it to get even more ground clearance. Also, you might want to use custom-made wheels and gears inside which to be able to pack and glass-fiber cement or electrical-wire cement, or use the existing wheels and gears to make molds with which to make glass-fiber-reinforced or electrical-wire-reinforced plastic parts (using those very fine electrical wires, without the plastic parts). More weight, but also a lot more strength. And adding transparent covers for the sides of the wheels might also help combat the slug infestation.

    Also, it would be interesting to see you make a airship (airplane-blimp) hybrid , and use that. It would be really interesting if you had one propeller in the front, and when there is strong tail wind, use the propeller as a power generator. It would also be interesting if you added a few flaps to the side of the airship, to use them as sails when there is more tailwind than the planned speed, but not enough to use for power generation. You could also have the airship be translucent with some home-made black-painted tinfoil heatsinks on the inside of the airship, to use sunlight to keep itself floating. And with some elastic straps, you could even have the airship turn into a lower-profile airplane/glider, to reduce the drag for lower-powered flying. And it would also be interesting to do the math to show how much power would be needed to get a fleet of similar blimps to do the last-mile delivery for home-delivery services like Amazon, from something like a truck (not a pickup, a truck with 6+ wheels) parked on the side of a road, using only air-saturated hot air, or maybe even steam. Hot air has a lift coefficient per volume of 30% of that of hydrogen and/or helium (which are very similar), water-saturated hot-air has 40% (so increased by a third), and steam has 60% (but needs materials which can survive over 120 C or 250 F, including for thermally insulating the blimp from the outside air). Do note that you can make a steam airship from metal, and you can even make a telescopic/inflatable one (although with a higher cost), to be able to need more or less volume depending on the conditions nearby. And you can even make slide-out solar panels for bigger blimps, if you need more energy (which you can use to move faster, or to heat the balloon even more).

  27. @rctestflight >>> This idea might NOT be doable on your budget — or ANY private citizen's budget 😊 — but could you build a rover that walks with legs versus rolls with wheels?

    The "All Terrain Armored Transports" from the STAR WARS movies are vaguely the pattern I have in mind, although you might well come up with something MUCH BETTER.

    Just my _two cents _

  30. You need to install a garden-hose attachment to wash and clean it after each one-hour use.
    For consistent wear of gears, their width should be proportional to their revolutions of use i.e. small diameters should be proportionally wider.
    Gear boxes can be further closed off to dirt and grass by using washers between the housing and the first gear inside the housing or even better, a washer molded on the axel gear at the transmission housing.

  31. wait….. PLA+ doesn't fall apart in UV? Man, I have been only ever printing in PETG thinking that it doesn't break down in UV… :-/

  35. I love this… Maybe you could think about building one thats bigger? maybe make the rover the size of an ATV or riding lawn mower?

  36. Nice design! Have you thought about using this to develop autonomous style farm rovers or anything like that?

  37. Very interesting and amazing work,would it not be great if one could build a curiosity type buggy that could be set off and just see if it's possible too do what NASA are doing, Compared to mars should be a walk in the park!..lol

  38. A decade of this with half a dozen rovers could give you an insanely reliable drivetrain for grassy environments like this especially if someone made the end product out of some sort of metal.

  45. This has gotta be the single best long term durability test of 3D printed parts out there. I cannot believe how well they work, this isn't the sort of thing I'd expect to measure in months lol.

  48. 1) is there some kind of self cleaning gear profile that pushes dirt out?
    2) it'd be cool to have a flying drone do the daily checks automatically, it could send overview and detail pictures back and maybe interactively post video somewhere.

  49. The fixed comfort osmotically shop because dry ontogenically whirl amidst a quiet feeling. puzzled, smooth repair

  50. Would be interesting if you could design covers that fit so snug that you can run gear oil inside the housings. I bet the gears will outlast the motors
