Solution to that thruster problem was just simple and absolutely brilliant.

[@GummieI]

And also funny to see the thruster "pulsating" whenever it turned or at the start of the uphill xD, so functional AND entertaining solution. 2 birds with 1 stone

[@Crazyclay78YT]

I literally thought to myself "I never would've thought of that." It just goes to show a non engineer might be the solution to an engineering problem

[@tomsterbg8130]

I love the gravity pipes too, but a huge flaw is acceleration changes. It may activate when you don't want it to which becomes a problem if you don't want to damage your robot, it has to deal with larger speed changes or be more fuel efficient which are mostly problems outside of SM.

[@villekorhonen824]

@@tomsterbg8130 Oh yeah, it is by no means the most efficient or problem free solution, but it works well enough in slow speeds and it just looks cool.

[@ig-rd5923]

Man, throughout the whole series, scrap man's solutions were actually very good. Obviously, someone with a lot of logic experience would be able to make marginally more robust solutions quicker, but all of these solutions were quite smart imo.

[@vibaj16]

Scrapman, to check if one input is active, but not both, you can just use an XOR gate instead of the 3 gates you used. To be more specific, XOR is active if an odd number of inputs are active (and XNOR is the opposite, so with 2 inputs it is active if both inputs are the same)

[@aetherian_wolf]

That only work if you don't care which one is active. He needed specifically if it's holding the blue ball and not the red ball. What he should have done is use a not and and gate.

[@vibaj16]

@@aetherian_wolf that's not what I was talking about. I was talking about for the turning, where he basically used 3 gates to do what an XOR gate does

[@Pystro]

My suggestion on getting across that beam in the bonus level: Counterweights that are lowered down when the road disappears. (Because they need to be lifted back up on the way back you have to actively lower them instead of them just dropping). You might want to put wheels on the counterweight, to help with sideways weight distribution while the counterweights are up.

[@roccov3614]

Yeah I put my wheels in a diamond shape and when the front wheel was on the beam I lowered my weight.

[@FruitJuice92]

i hope the creator of this challenge keep doing things like that because i love this format

[@mayronjunior139]

One solution to that final one would be to use the low friction blocks as gidelines that descend when theground is not seen.

[@Friendly_Neighborhood_Dozer]

Or when white is detected

[@photelegy]

I love how many more people get to experience how a programmer feels with the logic gates and the bug fixing 👍🏻

[@Bohnson.]

scrapman's handling those two gigantic balls really well..... as if he had experience with that

[@QuirkyView]

A good trick to figuring out what logic to program into something is to say out loud in simple words what you want to happen. So when you were puzzling how to get the car in reverse, it would be "When this and not this are active, drive backwards." so the forward ball sensor would be connected to a NOR gate which would go to an AND gate with the other ball sensor, and that's it.

[@dark-5825]

I absolutely love your practical/analog thinking with these! I would've tried to solve the thruster issue by making the thrusters turn off when going backwards, but thath little gravity trigger was so clever, because it solved potential issues elsewhere as well. Respect

[@anthonymondragon5043]

Potential tip for the beam. In one of Khan's multiplayer episodes with the monorail build, he had a system that would wrap around the rail. You might do something like that with friction blocks since they provided so many wheels. Hope this helps! :D

[@oriongaming1233]

try using sensors and the extra wheels to fold down to keep yourself stable on the beam

[@kendallguier1378]

This is simpler then my idea gj

[@kendallguier1378]

I was also thinking stop at the end and fold out an arm across the beam with a controller and bearings and grab it.

[@s0ulflre131]

To balance the car on the beam you could use sensors to detect the glass walkway and have them activate corresponding thrusters aimed downwards so if the right sensor detects the walkway above the left thruster activities and pushes the left side of the car up and vice-versa.

[@ckinggaming5bucketmadness766]

My idea for the last level is a 3 or less/more part centipede like creation that will detect the white line and let down a set of 2 wheels that would go along the sides of the line and life back up on the way back(perhaps with the usage of well timed timers?)

[@kendallguier1378]

White sensor into free bearing tilt sensor into balance thrusters White sensor middle 2 sensors outer sides(turning) just a grabber and directions after that

[@prestonbennett1897]

Absolutely brilliant way to turn off the thrusters. Impressed.

[@4lchemist904]

I love the tilt sensor, such an elegant solution

[@Milamberinx]

It was an elegant solution to a problem that didn't exist though.

[@Ben_6278]

i have no idea what's happening but it's so entertaining

[@lehazing5957]

Have it balance the same way a roller coaster holds on to the tracks

[@TheRealPauseacorn]

this series has taught me how to halfway do logic programming. like knowing the solution to the issue at 12:00 could be solvedwith an AND gate requiring both the sensor to be activated and the timer to be activated for it to stop. First episode I wouldve never thought of it

[@randomboitime4221]

The whole black line skipping issue could have been skipped (no pun intended) if scrapman just paid attention to how the first training car followed the black line in the first challenge. Very fun to watch them nonetheless however, it's wonderful :]

[@Thefallenslayer22]

!!! SCRAPMAN THIS WILL HELP!!! (sorry for the all caps) You have 8 sensors use 2 to detect the black line for forward one at opposite ends then 4 spaced evenly underneath so that if they detect the black line they will cause it to turn back to keep straight with one block space in between the sensor so the line can pass undetected until the bot is off course and use 1 sensor to detect the white line to activate your stabilizing wheels use 1 sensor to detect the trophy and activate reverse function and if there is any low friction blocks possibly use them also as stabilizers

[@aeresys]

Wow, that thruster solution is actually genius

Suggestion: I saw a cheese on a challenge where a robot extended an arm with a white piece to trigger the ending without going through the course. Here it would not be a cheese to pick up the trophy with a folding or extending arm, if you can make something long enough. I don't know what you have access to, a whole lot of pistons would be nice.

[@Orblets]

He does show the chest contents at the end of the video, he has 2 pistons and 3 controllers so some sort of piston extender and controller scissor extender thing to grab the trophy might just work

[@Nevir202]

Love how he didn't just make a line follower, in which case, the crossing lines would mean nothing, and cause no issues lol.

[@DeadBread.]

IIRC The reson why he doesn't do line followers, but instead, line avoiders, is that in Bot Factory 1, you have to build line avoiders, but in BF2 you can build line avoiders OR line followers, and ScrapMan didn't know how to make a line follower, so he just went with the standard avoiders for all BF2 levels.

[@Nevir202]

@@DeadBread. Ya, definitely a tendency to stick with what you know.

[@saturnring2jw]

I think the creator has his vehicle in every level. Good job with all that logic. I was starting to get lost there. ha.

[@mutevampire]

Wheels on the side that rotate down to hug the center beam after the wheel behind them loses sight of the road? With 10 wheels you could make a fairly long car, too. Perhaps one that anchors in place and stretches out with pistons, using the balance beam as a brace instead of the entire floor?

[@XeridoxVisualArts]

13:42 I thought "Just slow it down a bit" but your solution is probably better :)

[@rainielcanete4337]

My idea:first you need 4 wheels balancing the vehicle then when it detects the white line (the 1 block long thingy) the wheels rotate to the side of the 1 block long road, and then to make it back again when it has the throphy then it goes backwards and when it comes back and detects the black line again the back wheel only goes back to normal and when the front wheel get stuck, it also turns into normal too, #ScrapMan please read this if it works because i never have been in a video, thanks

[@qraz3228]

You can make a wheel system like a roller coaster, where there is a wheel on top, left, and right of the bar to keep it in place

[@sebastianusprime]

Suggestion for trophy level last challenge: Paint a block brown and put it over the sensor.

[@richardinman4091]

Wanna bet there is another sensor under the trophy right now that has to be deactivated for the other one to activate?

[@PlutozReal]

You have 10 wheels. Do 4 wheels normal. 1 wheel in front middle. 1 wheel in back middle. 4 wheels horizontal in the middle. When the ground is not detected the wheels lower. So you're grasping the rail on either side with the two wheel on top providing forward and backwards movement. Then just roll out grab the cup and drag it back.

[@DJLing]

I suggest a caterpillar approach! I mean, you got all those wheels, use em!

[@NassimBDK]

for the next challenge you have 2 solutions i can think of(untested tho): - paint your vehicle brown and make the sensor detect it - use wheels on the walkway to stabilize the vehicle when on the beam

[@Starlight-nu1zh]

Painting the vehicle won't work, trophy is painted a non-paint tool brown

[@richardinman4091]

Wanna bet there is another sensor under the trophy right now that has to be deactivated for the other one to activate?

[@RogueAero]

@scrapman put the low friction blocks on controllers or pistons as a guide for the rail. Set it up so they go down while a color sensor detects the white line and 2 side sensors DON'T detect the ground. Then a claw mechanism to grab the trophy and lift it up 1 or 2 blocks(assuming you can even pick up the trophy).

[@Kraxel-North]

Make two sets of three wheels, the outer two of which fold down to grab the beam once they don't detect the ground under them.

[@prestonthegod1717]

I love how the first level in this video is so complicated and genius that he forgets he can just paint his vehicle brown to complete the level 😂😂😂😂😂😂

[@bonesciencegaming3863]

Scrapman I have an idea, maybe make it detect a void and have a tram like system fold down to stabilise it and then retract it when it detects groumd

[@alexanderkrauss6266]

You could probably try it like rollercoaster trains work. Sideways wheels that coming down as it hits the balance beam.

[@JWhere_]

Solution to the last challenge: paint the underside of your vehicle brown.

[@limonlx7182]

I noticed that bearing issue in the beginning, was wondering how long it would take you to notice it.

[@roccov3614]

By the end I was using just 2 logic gates with the sensors. One XOR to indicate when you need to turn and then a NOR to flip that to indicate you need to go straight.

Do you think it would work to get across the 1 block line if you used a kind of system where the wheels are in the normal direction until you get to the line and then the wheels turn inwards so it is similar to how you would make a roller coaster cart?

[@kylewall9107]

Thought I had was would you be able to make a mechanism that extends out to pick up the trophy? Forgoing the balancing sideways portion (balancing to not tip forward may be a thing). There are only two pistons, but there are a number of bearings...

Is it orbin' time yet again? :D Nice build, though i would recommend "Better wires and bearings" mod so the connection spaghetti is easier to follow.

[@SpidermanFan92]

I would double the sensors on either side of the line so the interior ones can track the line but if all four detect black then just straight ahead.
