Tracked vehicle

Don DIY
US army tank tracks are available here: http://youshouldbuildit.blogspot.com/p/blueprints.html and DIY tracks Blueprints video. This is a slide show of my homemade mattracks made for my trike to haul firewood and timber out of the forest during the winter. Video shows a standard 25mm, 3mm pipe milled down to 2mm for fitting a bearing. First video of four in the homemade ATV tracks build series. This time I'm welding together the sprockets and turning bearing brackets and rear axle wideners in the lathe. See DIY sawmill. On ebay "personal tracked vehicle" plans. https://www.youtube.com/watch?v=HYLazxjcFLk   http://youshouldbuildit.blogspot.com/p/blueprints.html

3d printed
https://www.youtube.com/watch?v=jE9xyDmjvcw I've completed 2/3 of my track system and give it a test run. I've very, very happy with the results of the test. I also spend a lot of time in the video explaining the design and engineering of most of the parts including gears, drive shaft, axels, wheels, trucks and floating idler system with automatic track tensioner.

Harmonic gears are great, but they’re also superduper expensive, because they require all kinds of precision machining. Alexander Kernbaum, a senior research engineer at SRI International, has come up with an entirely new rotary transmission called the Abacus drive, and it’s a beautiful piece of clever engineering that offers all kinds of substantial advantages. See Gears robot.

 * https://www.youtube.com/watch?v=IzzWYvWjA3A copyright issues on Nero and Traxxas We have read online that there is an open lawsuit going on between Traxxas vs Hobbico. The Lawsuit is about patent infringement on the Suspension design of the ARRMA Nero, from Traxxas. Visually, to us at least, the cantilever setup has been long used - but by Traxxas, when in the RC world. To us, it looks like a close use of the Traxxas Patented Suspension (Our opinion only).

I would recommend using non o-ring chains if you were going to replicate this as the rubber o-rings didn't really like the heat of the welding!﻿ aming I think what John was asking, how is the drive going to be split, if it is only a single engine with no transmission then its the same as having a locked diff in a car and won't turn. He could possibly mount another two small centrifugal clutches on the rear sprocket with mountain bike disk brakes attached to each.  That would give him some slip in the final drive line and independent brake control of each track.  Good work EpicBuild.

Heng long
https://www.youtube.com/watch?v=SA1vb0Ua6vg video of first run on my latest project, a Heng Long 1/16 M41A3 Walker Bulldog RC Tank with Dual Mabuchi RS540 Motors. Modular 3D printed tank mounts and worm gear drive housings I designed on TurboCAD. RC ball bearings on worm drive. 3D printed beaing insert on drive axle with 16x8x5 ball bearing for output. Fabricated aluminum motor rail. Run with Sabertooth 2X12, single7.2V battery. Final drive ratio 23.64 to 1. Drop in 3D printed mounts use same stock mounting holes as oringinal gear housing. Had to custom make the spur gear hubs from a shaft coupler and a universal hub on lathe. The drive axles are fabricated from 5/16 grade 5 bolt shank and RC truck axle. Lid fit on the tank, motors are right under the air vents! This turned out so nice, wanted to share this with you. These mounts should fit in any Heng Long tank with any motor. What is really nice is to be able to change gear raitos you can't do with stock gear boxes. Will see how they hold up. Very tight fit but it works, mission accomplised.

The result is a miniature version of a true snowplow, caterpillar tracks, with blade and light projector mounted on top to light the way in the dark; everything is controlled by a remote control from the PlayStation 2. Let us see how our caterpillar robot is assembled, starting from the mechanics and then describing the electronics and firmware that is necessary.

Robot arm rotates on platform or lazy Susan bearing, rotated by a chain, sproket and vertical DC motor. http://www.howeandhowe.com/rs1-rbs1-robotic-ballistic-shield.html SWAT-Bot is the world's first mid sized robot designed solely for SWAT/SERT applications. It serves as a robotic ballistic shield, door breacher and vehicle/debris remover when the environment is deemed unsafe. The Robotic Ballistic Shield (RBS1) or “Swat Bot” concept was created in coordination with the Massachusetts State Police. It utilizes the RS1 base platform, a collapsible ballistics shield, and a hardened AR400 steel nose shield to protect those in the line of fire. Standard procedures for approaching a hostile environment means utilizing a shield barely larger than the human torso for protection. The “SWAT Bot” offers the operator and team adequate cover from hailing gunfire and explosive scenarios. http://hdwall.us/wild-animal/cars-drift-ken-block-wrc-monster-energy-subaru-impreza-wrx-car-desktop-hd-wallpaper-331753/ http://www.howeandhowe.com/rs1-g2-guardian.html
