Hello all, Been here for a while now and I thought I'd share my project with you, DoomBot V1.0. He's a big one, a little under 5 feet tall. I'm still working on the platform, haven't really decided just yet, but I did get 2 wheelchair motors. Nothing is wired up yet, I'm still planning on adding a bunch of stuff on it so we'll see. The arms are all dc window motors and a pneumatic cylinder. Comments appreciated!
Influences are T-600-800, Predator, Alien (I live for H.R Giger). I'm sculpting all the panels once all the hardware is crammed in. This is gonna have a real sick exoskeleton, both for looks and strength. See my website to get an idea.

Redzone's 2Nd Inmoov Build
So I started my second Inmoov without a name yet. I havent given up on Gideon, my 1st Inmoov, I have learned a lot from...
@stonewolf Ah dude I'm not one of those elitist types that hog knowledge...I'm always willing to teach what I know and I'm not afraid to admit I don't know something...I'm always "learning" so I never claim to be the "best" or an "expert" at anything because that's the downfall...and that's when you start sucking.
I only keep people out because of the nature of what I create. My paintings, sculptures, etc. At my late 30's, I'm finally confident enough to say " I'm done explaining myself".
I want to keep the Doom light, but hella strong. This is why I'm using carbon fiber, and Kevlar. Even now, you can hit this thing and it wont budge. Most "hobby" robots are fragile.
The problem with me, is I don't think this is "scary" or "mean" looking hahaha. But that's just me
I think he is coming along great I love watching this build. You are quite an artist. I can't wait to see how he looks with his skin the new face.
Marc is more than an artist... by the look and craft of his build he is a serious engineer as well...
Lookin' good!
@Richard R Yeah bro I'm an awesome engineer I used a PowerAde bottle for an arm bone cover! hahaha
@Dave Schulpius Too kind brotha. Yeah I'm liking how the "skin" is coming about, although now I'm having reservations of making this thing "organic" looking. I may leave it robotic looking, so I guess I'd rather call it "shells" now. I will post pics of my sculpting so I can show my process step by step, to those interested. I'm saving the silicone skin idea for a future humanoid build - that hopefully @Rich would collaborate on...
I am however sticking to my original idea to where the shells can be removed, and worn, and control the robot that way. The potentiometers are going to be contained in the outer joints. The only drawback is the Doom would be naked hahaha
@MovieMaker Thank you as always!
He truly is an amazing bot!
This is the drivetrain...the robot comes apart in 3 sections, the top body, the torso, then the drivetrain. Here you can see the "A" batteries, 4 18VDC drill batteries, DC/DC converter that puts out +5VDC, +12VDC and -12VDC. The motors are controlled via the 2 300 A motor controllers. I'm gonna have a "B" battery that will go on another section of the robot, and I have a DC UPS (Uninterruptable Power Supply) That will switch from "A" battery to "B" battery when the voltage is low (about 5%), it would also throw a digital signal which can be used as an alarm or some kind of alert that the batteries are low. I'm still figuring out a system that will charge the battery pack not being used while the other is working...
Any ideas you guys wanna throw around I'd appreciate.
@Richard R
Here's some photos of how I did the sensor on Doom's claw. As you can see I placed it on the bottom.
