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.
About this creation
E.F.O.R.S.B stands for:
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 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 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.
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
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.
