This is my original Great Ball Contraition (GBC) module. I made a car that carries the balls with Adaptive Cruise Control (ACC). I use Lego's Powered Up platform. More info and free instructions: akiyuki.jp/en/works/1667
5:15 - perhaps the yellow is losing out because it measures a shorter distance, since its sensor is on the inner side of the track? The straight tracks will have a noisier response.
@@tomwaligorski9882 could be both, no technology is completely flawless. theres gonna be a couple of false positives/negatives in there, the main uncertain factor is How Many i think one happens at around 5:32 - the cars all come to a standstill, but green bugs out a bit and starts moving again
HE KILLED GREEN!!! STOP BULLYING YELLOW!! These are awesome, first time I've seen the hub's in action used in multiples like that! Perhaps look at app cloning, instead of having to use four (for now!) devices?
That'd be perfect for both the visual aspect as well as reduce battery charge wastage - have a little single-lane rail yard off to the side with a lane switcher that counts the average amount of ball throughput (switching only when there's not enough balls to warrant more than 1 cart and if there's nothing near it to prevent derailment) to store some of those carts, and uses the same type of gate as the main feeder to hold them in the pen.
Another really great design. Having built a number of GBC builds with Powered Up and Boost, the issue is feed back latency between the phone/tablet and the hub as well as the variations in the sensors, they all have there own little nuances. Light also plays a big part, the bright recording lights bouncing off the glossy bricks does also cause an issue. When I built a sorting robot with Boost it had trouble between yellow, white and orange because of bright light
Nice design and execution! This exactly shows why Boost/PowerUp is not suitable for GBC. 4 phones/tablets, all the Boost/PowerUp parts and a lot of batteries! My whole family would be without phones for a week when I run this at LEGO World Utrecht :)
This will hopefully be achievable, when Boost adds in Multi Hub Support (which has been promised)... and as for cost of parts, and batteries - that's never stopped GBC builders before! ;)
I'm sure the new smart bricks make everything more streamlined, but I do miss how you could make complicated motions with kinetic machinery. Great stuff as always.
A great module (as always :-) ). I especially like the different possibilities of the cars to interact. The BOOST components offer great possibilities but there would be so much more possible if the BOOST or PowerFunctions app could connect to multiple hubs at the same time. Not only would we not need multiple smart phones for one MOC, a sensor connected to one hub could trigger actions of another.
I suspect if all the sensors are adjusted to match, then any set of 3 cars will push the 4th around. The set of 3 will bounce against each other, so the lead car ends up pushing the 4th car around. Well, most of the time. It would be a metastable system. The cars can be placed on the track so none of them are moving. If each car changes its following distance randomly, it will break deadlocks, and make it look like the cars are losing their patience.
Wow, this is cool. You could make a ball quarry using this system! Think about this: from the rest of the GBC, balls are randomly sorted into little mine shafts, big enough for these carts to travel through. The cars go in empty, and come out as if there were little workers inside the mine filling them. The balls are then transported to one of your bigger cars by way of conveyors, hoppers, and chutes, and are then dropped into the next module. Keep in mind that with the amount of balls going out, the next module has to handle large numbers. I would recommend the ball-dozer or your wave module.
you should add some rubber double axle connectors to act as bumpers between the two, unless they're too elastic and cause them to fall off the track too much
Thats genius! But why the hell we are in need to power these four guys by four Tablets/Phones? Thats just silly and one single table should be able to handle that with ease
@@SynchronizorVideos Nope. It is a stupid thing about the whole range of powered up motors and hubs. The hub must always be connected to a device or remote, otherwise they just stop. Also, remotes/devices can only control one hub at a time.
