E.F.O.R.S.B v2 . A large robot as large as the Robot's base. Mecha one made this robot to run over everything in it's way, except for it's bretheren. Its programmed to destroy the humans. . E.F.O.R.S.B stands for: Exo Force Off- Roader Scout Bot I built the first version back in 2008, you will see pictures of it later in this creation page. What this robot was built to do is go off-road mainly, but it can pull weights, as you will see later in the creations page. I built this with sets: 8108: Mobile Devastator 8274: Combine Harvester 8960: Thunder driller 8941: Rockoh T3 8527: Lego Mindstorms (1.0) Obviously And Alot more pieces, including alot of bionicle armor, by the green claws you can probably get 8980: gresh for the pieces. Problems structurally were making the robot Formidable and stronger, because the back of the robot has gearing that needed extra length, so it had to be longer than the front. And I learned from the first EFORSB that I needed to add bumpers to it to make it even stronger. Since the Motors were facing opposite directions, I had to make a simple gearing system to make all the motors move in the same direction. Now that im programming with RobotC though, I probably didn't need to do that, but its built nicely anyways. I currently didn't program it yet "im still learning robotC" and It may not be programmed for a long time, but when it does, I will post a video showing you how it moves, but not now. Here are the pic descriptions for you: Pic 1: Main picture, or picture of all the robot. Pic 2: front side of robot, showing Sonar and light sensor Pic 3: Top view of the robot from the front Pic 4: Back side of the robot "The red triangle piece is used for the trailer" Pic 5: pic of the simple suspension Pic 6: Picture of the under view Pic 7 & 8: Picture of the robot's suspension in action Pic 9: Picture of the back's under side, but covered for hand protection pic 10: Picture of the back's under side, shows the simple gearing system Pic 11: Picture of the front's under side, but covered for hand protection pic 12: Picture of the front's under side, shows the extremely simple gearing system Now for the suspension, and how its built. Suspension The robot's suspension is alot more simpler than the first, but looks complicated on the robot, because everything has to be connected in a special way. For example, My last suspension had alot of junk on it, while mine doesn't. I had to take apart the trailor to show you what the suspension looks like, but its back together don't worry. Back to the Suspension though, Jbrost76's Voyager on the NXTLog inspired me to make the first, and the second, and borrowed the idea of using the NXT turn table for the suspension, which is rather simple yet is very effective. Luckily, no structural problems were faced, except for adding wires in an effective way. I think you can explore the Pics so you can use the suspension for yourself. Now for the trailer EFORSB's Trailor I built the trailor just to test the robot's pulling capabilities. I haven't tested yet, because it still needs to get programmed, and im still learning about RobotC code. but I built the trailor with the Thunder driller, or at least thats where the black wheels came from. I gave the trailor those wheels because they would likely have more grip on the dirt than a regular tire, or at least mud. I tried to make a trailor with some unreal looks and design but with real functions, like the adjustable wheel "seen on pic 3." It wasn't easy, but I did manage to make one, I did have alot of bionicle parts, but balls and sockets aren't very stable in just staying in one position usually. With the robot's trailor, it could probably bring fire wood to you in a jiffy, though you would have to add more specail gearing for it to actually work. Now for the pics. Pic 1: Regular view of the trailor without the third wheel holding it up Pic 2: Regular view of the trailor with the third wheel supporting it. Pic 3: Under side of the trailor, shows you how it is adjustable. Pic 4: Trailor holding a plastic box Pic 5: side of the trailor itself pic 6: Robot with trailor "its hard to see, but you can see that the robot and the trailor are almost as long as the width of the door." Pic 7: Robot with trailor, with the same plastic box on it Pic 8: shows you how it connects to the robot "its connected upside down because the touch sensor already occupied the top, and that explains the red triangle piece. Go to This page to see the older version of the EFORSB, and the description on that. Program and Movie coming soon...
