LEGO Technic Chili Crawler with SBrick

Posted by Lénárd Pásztor
Hey, this is my Lego Chilli Crawler. It is an overall improvement from my last Lego Carrot Crawler: https://www.youtube.com/watch?v=w4d_Gx69NEg Eurobricks Post:http://www.eurobricks.com/forum/index.php?s=c50bef3337e282c244dc3f44ee4c3d27&showtopic=120645 Features: - Triangulated 4-link live axle suspension using 4 soft, black shocks. - 4x4 with one PF XL motor mounted parallel* to each of the two axles. A final gear ratio of 1:5.001, yes this may seem slow, but the enormous Super Swamper tires make up for it. -4 RC4WD Super Swamper tires. No, they are not Lego, I got them from a nearby hobby shop. - One L-motor for steering in the front axle, geared down via worm gear to 8 tooth gear, then a 12 tooth gear to a 40 tooth gear. The 40 tooth gear drives another 12 tooth gear that moves a 13L gear rack. - Portal hubs for all four wheels. Standard Lego Unimog for the rear axle for rigidity; custom triangular plate portal hubs on front axle for a steering pivot point closer to the center of the tire. - Good articulation, about ~55-60 degrees. - Controlled with an SBrick. - Powered by a Lego rechargeable LiPo battery. Say hello to the Carrot Crawler! This crawler has been a work in progress for a long time and is in its final stages. It includes an SBrick that is controlled by an iPhone 6! Features: -Triangulated 4-link suspension using the Lego soft shock absorbers. -One PF XL motor per axle (a total of two), each geared down 1:2.779. -Custom portal hubs for each wheel. -Ackerman Steering with slight caster angle powered by PF M motor geared down 1:3.333 including a worm gear. -Rechargeable LiPo battery box as power source. -Controlled by a SBrick and an iPhone 6. -RC4WD 1.9" Super Swamper crawler tires.
