Children and youngsters at coronary heart love Legos, particularly motorized Legos. It is enjoyable to dream up challenges and engineer options to eradicate obstacles. Or watch from the sidelines whereas somebody builds one thing intelligent. That is why Lego movies on YouTube are enjoyable to look at.
This video is titled “Driving Lego Vehicles within the Sand” and was put collectively by Brick Know-how, who additionally did one on parallel parking and one other the place they constructed a sizzling rod with a working clutch and four-speed gearbox. They’ve various movies on their YouTube channel, which is sort of a cross between Engineering Defined and Lego Film 2.
They attempt to resolve a difficulty that frustrates four-wheelers in every single place, getting caught within the sand. Beginning with rear-wheel drive, they be taught wider wheels make a distinction, as do the steering and a locking differential. Weight distribution additionally performs into the equation, as individuals with rear-wheel drive automobiles will let you know. Including weight over the drive wheels is without doubt one of the keys to not getting caught.
Whenever you add obstacles, it will get more difficult. Lego limitations, potholes, slopes, and hills eradicate the direct path to the end line, which suggests the rear-wheel drive automobile can not energy its means by means of. That is the place the all-wheel drive turns out to be useful, together with one other locking differential.
One of many largest issues that makes a distinction is tires. Not solely does the tread design have an effect on the car’s efficiency, however its form additionally impacts it. Tires with a flatter-shaped tread are rather more efficient at maneuvering by means of the sand than ones the place the tread is extra rounded. Moreover, the variety of tires makes a distinction. Probably the most profitable design used a six-wheel drive configuration to additional support weight displacement. That is why you see heavy vans with further wheels fitted.
The six-wheel drive truck with impartial suspension is essentially the most profitable car. It navigates all of the obstacles aside from the occasional cat, which scouts out of the sandbox in an try to make just a few obstacles of its personal. Because the closing iteration six-wheeler has a flatbed, the Brick Know-how crew must also take into account including a scoop to maintain the litter clear.
