Mustang Shelby GTEX AWD (42138 MOD)
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingFew months ago I modified the set 42138 with one BuWizz motor for driving the rear wheels, one PU motor for steering and a BuWizz 3.0 to power the model. This MOD was really fun and all BUT, deep inside I knew I can do better, especially after being inspired by upcoming Bolide (and a bit frustrated by it's lack of AWD). So after a lot of trial and error, fiddling and trying literally all kinds of component placements, I came up with the following MOD: So you may be thinking, It's a different color, so what? It has a fancy diffusor, spoiler and a few body mods but what's different? Well... The answer hides on the underside photo: Yes, this small 1:16 model has all wheel drive with differentials! Not only that, but the rear axle allows for torque vectoring which allows me to fine tune handling, especially adjusting understeer/oversteer. The model has been assembled and tested with real bricks, I will post more media soon. AllI can say for now is that performance is excellent, there is plenty of torque to spin all 4 wheels and it can even do AWD powerslides.
[MOC] WAVES - A Kinetic Sculpture
Nalyd997 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingWAVES - A Kinetic Sculpture Hi everyone! Just released a video of my latest sculpture in my series of explorations into movements of the sea. This one is inspired by the great work of @aeh5040 with his synchropods. Really happy with how this creation as well as the video turned out, recently upgraded all of my camera gear. Hope you're all doing well!
Mathematical Analysis of a two degrees of freedom differential system
TechnicBrickPower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHi All, Just made a video that presents an analysis of a two degrees of freedom differential gearing system that I have been basing some previous designs on. I use this to explain why the "Slow reverse Car" mechanism did not work as expected. Only for maths fans - don't watch otherwise ;)
63 Speed Gearbox with multiple reverse speeds
TechnicBrickPower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI have made my first gearbox using differentials. It's a 63 speed gear box using 6 selectors. The gearbox implements all gear ratios from -32:1 to 31:1 using five differentials.
[GBC] Hybrid Construction Site Module
LegoGBC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingAfter months of building (well, life got in the way) I've finally finished building my biggest, most complex GBC module. It's a hybrid GBC (uses both mechanical and pneumatic functions) of a construction site-like-crane operation. Here's the video. A detailed description of how the crane works is written below The 6 step movement of the crane is done without using any sort of programming and no mechanical timers - it uses 3 differentials (one heavy duty) to power 4 outputs: 1) The crane rotation 2) The crane's claw (a pneumatic switch) 3) The crane's boom (a pneumatic switch) 4) The PF switch used to reverse the motion The 6 step movement: 1) Close the claw 2) Lift 3) Rotate 4) Release 5) Rotate back to original position 6) Lower So how does it work? Differentials send the power to the 'easiest' output. So the first, easiest function is to close the claw (rotating an axle which then changes the position of a pneumatic switch) -to grab the crate The second easiest is to open the boom's pneumatic switch -to lift the crate After that, the crane rotates until it's blocked at it's final position (the drop position). The power is then sent to the PF switch, which reverses the movement: -The claw opens -The crane rotates -The boom lowers Notice how the boom lowers AFTER the crane rotates back to it's original position (while it lifts BEFORE the crane rotates) - this is done so the boom won't lower in the wrong position (where it drops the crate) - a rubber band mounted on the boom's switch makes sure this happens: -It's easier to change the switch to it's lift position than it's to rotate the crane -It's harder to change the switch to it's lower position than it's to rotate the crane back. There are many (really, many) more small mechanisms in this module, but I think it's better to see those in the video :) Thanks for watching!
