Hi, that one is my robot. It's a 'ringspinner', a ring shaped weapon spins fast around the outside of a normally stationary robot. The gyroscopic effects of this can be weird, and in that case it was flipped up with the inside spinning within the ring stalling in the ground.

@@teslacoil4335 Not James (but I was running one of the other spinners in that melee). Spinners in 150g bots can seem to do nothing, or deliver massive hits that throw/destroy the other bot (or themselves). It depends on how much "bite" they get on a hit, which depends on weapon diameter weapon speed, engagement speed, and probably several other factors. This is true in any weight class, but in 150g bots the power to weight ratio is crazy, but similarly the weapon speeds are probably faster than they need to be (because of the high kV values in small brushless motors) so they tend to "grind" on the other bot, up until they actually get good engagement.

Expo won't help. I use these N20/N30 motors on micro crawlers and the cheap tiny DC speed controllers are often inherently bad at low speed control. You get nothing before about 30% throttle even if you raise it super slowly. The reason for this is that the motor's coils act as an inductor and the motor controllers are set up for efficiency and quietness at high speed, which means they run a PWM frequency above hearing range (20kHz+). If you're well versed in analog electronics, you'll see that the inductance and resistance of the motor form an RL frequency filter, reducing the voltage across the armature at low motor speed. Adafruit released a whitepaper on this and it was a revelation to much of the hobby community, including me. So if you're building a crawler or robot and want low speed control but don't mind a slight lack of smoothness, a sub-audible PWM frequency like 20Hz is far superior. All the good quality crawler ESCs are set up to change the PWM frequency as well as duty cycle based on throttle. That way you get maximum power across the speed range.

(10:08) "using design history, I can just go back and change the shell thickness". Yes, you _can_ do that, but I've found it a lot simpler to just declare a parameter and use it in the course of modeling the object. You can start by setting "shell_thickness" to (say) 3.0, and then when you model your shell just type in the parameter name as the value. If you want to change it later, you don't need to track down the history element to change its thickness: change the parameter directly and it will be applied in the entire design history (which can potentially use this value in a lot more than just one step!). It works in sketches too, in case this feature of the object was derived from sketch lines.

Straight up when I figured this out it started saving me so much time on designs it was crazy You can even have parameters that are functions of other parameters. For example: You have "wall_height" set to 6.0mm and a circle cut out in the middle that needs to have specific spacing from the top and bottom, you can have the size of the circle be the parameter "wall_height - 2.0mm" now the circle will always have 1.0mm between it and the top and bottom.

@@Gormadt Yes, being able to use them in formulas is great, I use it all the time too. I think there's only _one_ place where I've had trouble using them, and that's in schemas when drawing an N-sided polygon, where N would be the parameter. For example if you start with an hexagon centered on a point and with a certain radius, and want to change that to be an octagon by updating the parameter from 6 to 8. I just couldn't get that to work, even with a "unit-less" value and all, I never managed to get F360 to accept the value. If there's a workaround I'd love to know!

Tiny robot mischievously pushing everything off the table made my day lmao

it should totally be "Charity Case", on account of the bands used for treads

Make an O-ring groove in your drive wheels that will preserve the crown profile when an O-ring is around the wheel. That way if you loose a belt you can still drive. It won't add much weight and give you redundancy.

the forks might have to be closer to the ground. maybe also redesign them to be sheathed in the bots front, since they're relatively flimsy and your only weapon. I'd suggest making the interfaces angled, so they don't have the tendency to get stuck while lowering them into their sheath+scooping position. oh and then I also wonder if you have enough weight allowance to add some metal spikes on the upper surface of the fork, to keep enemies from sliding off the fork too quickly... maybe just superglue sand on it. it would probably be better to have it grip only in one direction though, so they can slide on easily, but can't just slide off.

The softer, the more grippy usually.

This track design is genius! Thank you so much for including the step file!

one of the wonderful things about this weight class is how many hilariously easy+cheap to get materials actually work pretty dam well for structure in a bot. here's a great example which do you think has more structural integrity per weight as a side panel: a sheet of titanium or a panel of decent quality pvc foam? even the cardboard from a cereal box ends up being surprisingly viable and both of those materials have the benefit of not transferring shock to the rest of the structure.

Crowned pulleys are a genius bit of engineering, you'd think you want to make pulleys with the inverse curve like a rope pulley, but for a flat belt this causes the edges to "walk" up the slopes and come off the pulley!

I think it's worth mentioning that Fusion 360 is FREE FOR PERSONAL USE, with minimal restrictions. The biggest restriction for me has been the "10 editable files", but you can change which files are editable ANY TIME, as often as you need to. The price of entry kept me from using Fusion for a LONG time, because I thought you had to have an educational license to use it for free, and had a really hard time finding the magic phrase "Free for Personal Use". It's almost as if Autodesk doesn't want people to know about that option, and pay for the yearly or monthly subscription when they don't need to. I will probably subscribe to the annual license eventually, but I haven't needed it so far. Honestly, the software is FAR more powerful than my skills in using it so far. As I grow as a designer, my needs may grow as well.

For the name, my suggestion is Lucas. Some time ago there was a YT series "Lucas the Spider" that featured a cute animated spider, and this bot does remind me of that little guy, especially when filmed in macro. As for Fusion, would be an amazing piece of software if it was "buy and download" instead of "rent from cloud". Besides, the "all models you upload now belong to Autodesk" part of their contract seems fishy. At least it did when i looked at their user agreement some time ago while considering using the service. Still, cheers to them for sponsoring this video, it is a good one!

"Larry the Lifter" I can not wait to build one of these, thank you sir !

Making a few of these for our library makerspace. The video says 50:1 gear ratio what rpm were they?

Great video and build, how did you manage the weight ?

I would min/max the electronics. Use motor wire, enamel coated wire. Replace all wiring with it. Remove all pin headers from the boards. Maybe even go as far as to re-design the boards using only the required components and move those components to the new boards. Or, combine the speed controller and receiver into one board.

Just a quick question What RPM are the Motors? I work at a Library MakerSpace we have the parts printied and are ready for the next step?

I had a class in middle school where we had to use Autodesk and I just couldn't grasp CAD back then, haven't really given it a try since, but that kinda stuff is still beyond me

Crowned pulleys! I've never heard of those before but it makes so much sense once explained. I'm going to need to remember this for some projects. If you like a spider name, the Peacock Spider. Otherwise, Sir Lifts.

Hi, you have a list of the other electronic components you used? Thanks!

What about using continuous rotating servos instead of the geared motors? They generally have a lot more torque and you can increase the voltage to up the speed as well as changing the wheel diameter. It also makes things a lot more simpler.

Way, way too slow.
