  1. I had another thread where I was asking about a differential for Kerbal Space. I decided to build one and after polishing it a bit I'm ready to show it off. Works in 1.2.2 currently using the Infernal Robotics plugin, TweakScale, and ColliderStrikesBack for intra-vessel collisions. Doesn't explode with cheats off either thus it would work for campaign players. This one is jammed full of features! Selectable drive modes..... * Left wheel drive with low torque (slips easily, may be good for traction on slick surfaces) * Right wheel drive with low torque (Right drive engaged but not locked, left disengaged) * Right wheel drive locked (Right drive engaged all the way into lock, left disengaged) * Left and Right Wheel Torque Biasing Drive (Both engaged but not locked) * Left and Right Wheel Locked (Left engaged, Right engaged fully into lock) * 3-Way custom gear ratios (Move pistons individually and asymmetrically) About the 3-way ratios... Since each piston is independently movable you can underdrive the left or right wheels by retracting a few on only one side. This would produce a yaw effect for turning or allow you to essentially have more than one rear end speed if you do it for both sides. Start with 4 out for slow crawling speeds and shift 4 more out for high ratios. Should be all we need for some serious fun! Turn on subtitles (CC) for a walkthrough as the video plays. Recommended. I'll get the craft uploaded and provide a link shortly.
  2. Lately I've been using the infernal robotics joint parts to create usable U-Joints. Wanting to build a 4x4 off roader I took the engine model from the ICE engine mod (purely for looks, not using their wheels) and then bolted an IR rotatron at the end of the motor. Then of course I attached the U-joint and then the driveshaft, and another U-joint and finally that goes into a non-powered rotating bearing. Looks exactly like a real setup and by spinning the shaft when moving it looks real. It even articulates properly if the angles are kept reasonable. EDIT: Uploaded some Photos: http://imgur.com/a/Sqybh EDIT: Uploaded some videos below too inline. Here's the direct links. Kerbal Space - 4x4 Off-Roader with Simulated Differential and Driveshaft. Kerbal Space - 2-Engined-Driveshaft-Driven-2-wheel-drive Drag Racer Problem is there is no actual differential available to get this power to the wheels. So I had to "cheat" and add rotatrons again for each wheel coming out of the simulated differential. By driving all at once it "looks" like a driveshaft is powering the differential. Pretty cool! Looks very realistic to see a driveshaft working as the wheels articulate. It even properly "snaps" as it rotates by not using a linear speed as the joints bend. Using the bearings from IR I can even make multi-piece drive shafts. Worked way better than expected and got me excited. So then I decided to simulate the idea of driving using these shafts and just ran parallel driveshafts to overcome the diff limitation. I used multiple 45-degree Ujoints to basically bend the shaft 90-degrees so each shaft was dedicated to the left and right wheels. By then using two motors I got a rear-drive tractor built that drives without using any actual wheel parts. I attached the large heat shield scaled up for the wheels and it gets the *perfect* amount of traction. I even get wheel hop when making an independent suspension and less when making it a solid design just like in real life. So with all this said I have a quick request for help making a mod. I want a quick and basic hack to existing models to make a real differential that works on rotation. Should be easy to tack 3 IR rotatrons onto the Ground Pylon and simply transfer rotation torque from any rotatrons to the others . So if the input shaft rotates 90* then the two output shafts also forcefully rotate 90*. Basically the same if either side receives a torque load it would transfer into the other two rotatrons. Eventually more logic could be added for limited slip functions of a rear-end multiplier. (Shiftable 2-speed rear like a semi would be even cooler) I just registered here and this is my first post so I'll wait to upload photos until after this gets approved. I'm also a rather crazy software engineer well versed in C++ but not at all in C# but I'd be happy to code this if someone could point me towards what to do. Appreciate the help.
