Building a Hydraulic Lego Excavator
Ғылым және технология
Building and testing a remote controlled hydraulic excavator with Lego. The excavator includes 6 motors controlled by a BuWizz 3.0 (a remote control and battery unit).
An electrical slip ring is used to connect the 2 track motors through the rotating turntable with the battery box. 2x CADA micro Motors are used to power the tracks. They are small, providing high torque, and having low RPM.
The turntable is moved by a Lego small angular motor for space reasons and because of the low RPM, which provides better control of the superstructure.
3x Lego Technic Powered Up Large motors drive one pump each. To make the small Peristaltic pumps, a Lego part had to be modified by drilling holes. The pump works with Regular Lego pneumatic hoses. It builds up a lot of pressure/vacuum, enough to operate hydraulic systems, and it works in both directions.
The Hydraulic cylinders are actually Lego pneumatic cylinders. They are not intended to be used with water as the metal parts could corrode. To avoid this, I used a mixture of windscreen wiper fluid and water. The system requires some air, as the 2 cylinder chambers are different in size and therefore require a different amount of water. Each pump powers its own independent circuit and, respectively, 1 excavator arm joint.
The PS4 Gamepad is connected to the BuWizz 3.0 Bluetooth Unit with an App called Brickcontroller2. The app allows the user to assign buttons of the gamepad to individual motors. The analog sticks of the gamepad resemble the 2 joysticks of a real excavator, adding more realism.
The design and proportions of my Lego digger resemble the CAT 390L, which is why it is in Lego minifigure scale.
The hydraulic system works without fluid by pumping air. However, the movement is not accurate and lacks power.
I made 3 custom parts that are 3D printed: a slip ring mount, a pump housing insert, and an excavator bucket. However, the excavator would function without these parts. The slip ring does not need to be mounted; the pump insert could be attached with sticky tape, and the Lego Bucket would still work despite being big. However, I greatly prefer using a custom shovel.

Bad day + brick technology video = good day
Idea: Can you make a truck that comes with this set, in which the excavator puts the sand or whatever it wants to, and then the truck can go wherever it wants and drop the sand? Like a dump truck which has a bed that bends down to drop the sand, and has a flap on the end to stop the sand from falling out? Edit one: This sorta blew up?? More chance that @BrickTechnology sees this.....

Nice video. I always struggled figuring out how to present actual sand digging, but the way you did it by laying a full layer underneath the excavator makes sense. It's so simple
This might be the best Lego related video EVER. Advanced design, building and very funny. Great stuff!!
Reminds me of my middle school science project when I made a hydraulic excavator. Little kids wrecked it up before the end of the day 😂

Great build and the prints look awesome. I personally would have gone for a direct hydraulic with one pump-cylinder per work-cylinder. Your solution is more compact indeed
Note that not all Lego pneumatic parts work with water. The switches in particular break, as my brother discovered waaay back. Unless they improved it since, which is very possible.

Peristaltic pumps are commonly used for small precise pumping, like in medical devices. As a bonus, the liquid doesn't touch anything other than tube, so it's easier to sanitize.

Im not gunna lie, hearing the exact same sounds that a real life hydraulic excavator makes, but teeny and high pitched, made me giggle. All coming from this accurate lego creation. Great job with this; It really shows how those machines work.

I just want to say how much I throughly enjoyed the epic excavator ending montage. It was beautiful.

Tbh, it seems like the center motor was struggling to stay balanced on rotation, but that 3d print to gap close and fit was clean. Also really cool use of the hydraulics. I would love to see a build that demos the use of the servos as well. 10 out of 10 would watch again
Excellent, I've been wanting to make a custom pneumatic excavator for a while but air power just doesn't cut it for speed, power and accuracy. Surprised by the amount of power those peristatic pumps can produce, it's a game changer. Thanks for the inspiration.
love the addition of the 3d printer!
