Just had an idea. Would be nice if Roomba had a camera and a sentry mode while your out. Plus the ability to “take over” control from the auto computer to drive with a phone so you could check your house out when away. Other idea. Linear actuator to lift front combined with tank tracks to climb stairs.

In my humble opinion, you don't need stronger wheels. What you need are rudimentary suspensions for your Hot Rod Roomba. I believe that new suspensions would also help with the handling problems. A more flashy painting would look good, too! 😉

[@electrosync]

Maybe some simple urethane spacers or something? A paintjob would be nice too.

[@Mr.Glitch247]

I mean, you're already 3d printing the wheels, why not just design them to flex a bit? I'd try some "compliant wheel" research if I were you.

[@AndyGneiss]

@@Mr.Glitch247 Perhaps a spoked wheel design where the spokes are shaped to act as a stiff spring for the compliant idea. I wonder what sort of plastic would be suitable for that job.

[@fairguinevere666]

@@electrosync Yeah, my first instinct would be something like that between motors and chassis, as longboard wheels can go really fast with decent stability. Something in the 60sa range tops.

[@electrosync]

[@DanteYewToob]

You definitely need suspension to keep the wheels on the ground. Rebound is very important in a drive layout like this because of one wheel has even slightly more traction it careens out of control. You want the wheels to hit small bumps and immediately spring back down into the road. Suspension isn’t just about a smooth ride, rebound is arguably more important!

[@bradleyrigby6105]

Great job on this, one idea i have for anti wheelie v3 is to basically have it like an old ball mouse, so it can spin around with less resistence and improve the durability of it

[@electrosync]

Great idea!

[@theaveragepro1749]

maybe make the wheel out of teflon or some other low friction/wear material

[@Hellsong89]

Would collect all kinds of crap and potentially jam if not clean surface, but there is ways around it, just that those demand space. I would probably attempt on instead of that build in servo the adjust the angle of the wheel based on gyro values as kinda thrust vectoring in a plane steering type of thing, but it should be lightning fast to response and have more weight on the wheel, so it can self correct chance of direction when no input is given and maybe adjust those steering values based on its speed so it steers less in higher speeds.

I agree with Maker-Mindset, a suspension system of some sort should help with the impact problems. I also think a small gyro in the steering control would help with avoiding collisions in the first place. It would need to be as close as possible to the centerline of the Roomba, and would take some tuning to get it working right.

As a lifelong rc enthusiast and mechanic I’ve found this very entertaining! and I’ve got some suggestions, for the wheels and tyres how about 1/8th scale buggy tyres or some bsr foam or even Traxxas xo1 wheels,and how about a gyro for stability a combination of gyro location and tuning along with center of gravity adjustment should see it dead straight but the biggest gains will be in a semi pneumatic tyres or Eva or hypalon foam giving it some suspension keep the chassis rigid and simple suspension could work but adding suspension with huge unsprung mass would not handle as well as just tyres with give

[@SpencerPaire]

Great build! I think those urethane wheels are a great touch. I wonder if there's any space to add ribs or at least a thicker head for those wheels. And you may be able to save those plates by epoxy-ing metal or fiberglass for more rigidity. Next idea; make it suck. But like REALY suck by using an EDF to make more downforce. Might cheat you into better handling, lol.

[@electrosync]

Thanks! The urethane casting was new to me - it's actually pretty fun (but smelly). There are actually ribs on the rims, but I could only fit 2 mm on there, so they probably have limited effect. An EDF is a great idea! Where my logo is in the centre of the Roomba actually has direct line of sight to the ground if you remove a few plastic parts...

[@adrianbik3366]

What's an EDF?

[@DerKaktusAvant]

You better make that Roomba fly

[@LuannTM]

Really impressive job m8! Some thoughts that may help you develop it! You're dealing with high speeds, considering the project size. So, if you want to go faster, you should try to add some weight to it. That will provide more grip to the rubber wheels. Or (but I don't think it's worth because again, the project size is small) try to improve down force or reduce air resistance as much as possible. Also, the wheels. Try using a softer material, that is shaped like a proper rubber tire, hollow inside. The rubber tire plays a big part of the suspension system in modern vehicles, and considering that you're using electric motors, that transmit power and accelerate without delay at all, a subtle force is transmitted directly to the wheels, that may or may not be too of a suddenly for stiff rubber... Thats why top dragsters have soft tires... so, it's a good ideia to avoid losing grip. Another important thing is that the project doesn't have any kind of shock absorbers, like suspensions or dumpers. So what happens is that all the reaction forces that hit the wheels are directly transmitted to the chassi itself... And considering that you added a lot of 3d printe parts, all this undamped energy will damage these 3d printed parts. That being said, adding a suspension and the arms mechanism will definitely raise the overall height of the project, something that we don't want... For this reason you should also redesign the power train itself. The current system connect the motor to a planetary gearbox set and a wheel, all in the same line/plane. Keep the current location of the motors and the misalignment created by the new suspension mechanism and the wheels can be corrected using a dual universal joint. Kinda like in this image: images.app.goo.gl/wdp5oSmsmAtZTY15A Also, if you're ideia is literally "make the fastest vacuum cleaner robot of all time" because fuck it, let's put this thing in the Guinness world records because YES, power delivery should skyrocket m8... Drain the batteries in seconds if possible, delivering the maximum energy possible to the engines for the maximum nominal RPM possible (before the motor blows itself)... Keep going!

[@electrosync]

Thanks, those are all awesome ideas! If I make a follow video, I think I'll go full mods and ditch my self-imposed rules.

[@Lumia_Light]

Some form of a suspension system can help a lot with the harmonic bouncing that is likely the culprit in breaking the wheels. Also, i think with this design i would implement spherical tires as method to prevent the wheelie. These dont force the roomba foreward like a cylindrical wheel does. I'd also make sure that the chambers that these spherical wheels are placed in have suspension too.

People coming together to help you improve the speed Roomba even more is great.

[@reverse_engineered]

I built a combat robot with a similar shape and speed to what you are using (scaled down). One thing that really helped with handling was adding in a heading control. I used a micro drone flight control board that had an onboard gyroscope. I wrote some simple software to read the amount of yaw commanded by the RC receiver and compare that to the amount of yaw measured by the gyroscope, and with a basic PID controller, adjust the difference in power to the left and right wheels to try to keep the measured yaw equal to the commanded yaw. It worked great for high speed attacks on uneven surfaces with an imperfect chassis. Another thing that might help is torque control. By limiting how quickly the power to the motors can rise, you limit the amount of torque supplied to the wheels, avoiding slip that would cause you to lose control. This also limits your rate of acceleration, but you're aiming for top speed, not a quarter mile time.

[@VigilantnotMilitant]

To continue this silly saga, you're wearing over-the-top safety gear, in a kitchen or dining room you've padded, and you race modded Roombas to see how quickly you clean up the toddlers split Cheerios. Each Cheerio takes a tenth of a second off your time or some other gimmicky play rule. Seems like chaotic good to see Roombas cleaning up Cheerios waaay too fast. Would also be dope (though decadent and wasteful) to include jumps lol

[@Metallica4Life1995]

For the handling issue, what about using some sort of gyro/compass to keep the Roomba on a specific heading, you could probably use an Arduino with a 3axis module. Then directional inputs from the transmitter would adjust the desired heading for the Roomba to match, it might need a bit of tuning but I bet once it's perfected it'll handle much better and have active stabilization, allowing you to focus on hitting higher speeds without the worry of having to adjust steering as well

My go-to filament used to be PETG as well. However, try printing your high-stress parts with a carbon fiber reinforced Nylon. It's nickname is black aluminum. Honestly, it's replaced needing to machine aluminum parts in some of my niche projects. Slicer settings tips: Use a cubic infill pattern for strength in all directions. Concentric top and bottom layers for things like wheels. Wall thickness is more important than infill % when it comes to the strength of a part. Values over 50% infill give only minimal increases in strength. Using 100% infill will throw off dimensional accuracy for small parts.

[@reidprichard]

Why cubic over gyroid?

[@stevehazim5823]

@@reidprichard Cubic infill is composed of 3 dimensional triangles (pyramids). Triangles are used in construction because they are geometrically sturdy and distribute the load experienced to each wall of the triangle. Cubic infill is great for prints that need compressive strength. Gyroid infill does print faster, but is better for parts requiring shear strength.
