New Bot Under Construction - Noles-d (nawless-d)

So my life is finally at a better place and it's time to get back into robots. I have been watching all of the great builds and just couldn't stand it any longer. I've started construction on Noles- D (pronounced Nawless-D), my Non-Lethal Security Droid. I am using a bar-b-que grill for the main body and constructing the base and drive system myself. He will use a tracked drive system with wheelchair motors. The non-lethal part includes twin airsoft machine guns, a paintball gun, and twin rocket launchers. He will also have a gripping claw and 5 DOF arm, along with on-board computer and array of sensors. I am using the V3 boards with Noles and have converted them to USB connect since I have an on-board computer. When completed he should stand a little over 3 feet high and weigh about 150lbs. The base section is 1/2" oak plywood that will be covered with carbon fiber. Here are a few pics of my progress so far. As always, community suggestions and assistance is always appreciated.

Also, if any of the community is in the Phoenix area I would love to meet up and discuss projects - help each other out, etc.

This is the base drive section so far. I should start coating it with carbon fiber tomorrow.

This is his claw, it uses MG995 metal gear servos for grip and wrist. Should be strong enough to get me a beer from the fridge.

This is one of his rockets modified to be fired from a tube. I am using ABS drain tube.

Here is the grill I got from Goodwill for 3 bucks. It had never been used but should work perfect for me.

I cut out some acrylic to mount up inside the grill dome to house the bulk of my electronics. The computer will be on the base and easily accessible.

I've started attaching some electronics - main EZ-B board, cooling fans, voltage regulators, etc.

A big part of this security bot for me is intimidation. If they are intimidated they will leave. But I also want security monitoring and a functional service droid. One EZ-B will control the bulk of the work, while the second one will mostly control the arm. I will post more as I make more progress - and beg for the input of the community (truly the best resource around).

I love the idea of your project.The tank drive could be a problem in my experience.It does not make for efficient maneuvering and it uses a lot of battery power.One design i saw on servo magazine or Robot magazine was a outdoor patrol bot that used some 12 inch lawnmower wheels with a heavy duty caster,Great mobility. I do like the intimidation or looks of a tracked base robot...I hope tracks work out great for you....Keep up the good work.Check out some of my robots on project showcase.Hope to see your updates soon...This is fun!:)

Can't wait to see it built and in action... Maybe you should has called it Lawless instead....:P
#3  
@rb550f - Yeah, I have been creeping on all of your builds. Very impressive.

@Richard R - I like that, i"m still toying with the name. Noles-D was just the first thing that popped into my mind. It's kind of empty in there so lots of room for stuff to pop in.
;)

This is pretty cool Bret! If you run into problems with lateral strain on the wrist, may I suggest these servoblocks. It will put the weight of the beer can on the bearing instead of the servo.

{Here is an igniter for the rocket......Shhhhh....you didnt get that from me}

Looking forward to a great bot. build. Cool idea.
#7  
Welcome back to building Bret! I'm so glad things are going well for you. Cant wait to watch the progress. Maybe you should consider changing it's name to Webber. :P

No problem Bret. Welcome back.

Bret,
Great to see you back into robotics.
Looks like a cool project and the claw is great.

I love the idea of a intimidating security robot made from a grill:P I can't wait to see the finished project!
#14  
It will be the Webbinator (thanks Dave ;)). Yeah, nothing lethal, just intimidating and painful. haha
#15  
Currently working on a Larson scanner for a little more intimidation factor. I will upload a video as soon as I have it operational.

Looks like a great project.

Evil Mad Scientist make a larson scanner I used with Melvin for a short time, it's open source too. If you need one I'll dig out the link (although it sounds like you have an idea in mind for that).

Glad to see you building again!
#17  
Well with budget cuts in all the Webbinator is going to have to multi task... Strap a propane tank on him so when he's not keeping riff raff at bay with his flamethrower he can grill you up a nice steak dinner... :)
#18  
Ooh, I like that - cook a burger, cook a burglar....
#19  
Okay, here is a quick video of the Larson scanner installed in the Webbenator.

Here is the camera - it is IR for night view.

<singing this like Michael Jackson's Thriller>
"'Cause this is GRILLER, GRILLER night
And no one's gonna save you from the robot about to strike
You know it's GRILLER, GRILLER night
You're fighting for your life inside a killer robot, GRILLER!"

I'd make that the song he plays in attack mode. LOVE the Knight Rider/Cylon LED scanner. Every robot needs one! hehe

If you gave it some red/blue flashing lights, some security decals and some bright/blinding lights I believe it'll perform security very well.

I love the idea of the rocket, but depending on your neighborhood or it's area of operation you might find folks react negatively. If you make it detachable and add it on like for shows, parties and Halloween the rocket launcher would be awesome.

@Bret, That's one of the things I like about you, you always think BIG! Welcome back. What a comeback!

@Justin, Very Funny! Griller. ha!ha! fits right in with the 4th of July celebration.
#24  
I think Justin has something here.... Griller is an awesome name for your bot....:D
#26  
Got the main interface board installed - starting to look less like a bar-b-que and more like a robot...

Looks awesome. Do some full robot shots. It helps give a sense of what's been accomplished.
#28  
I will do full shots when I get that far. Building his upper and lower sections separately. Been working on the top with the electronics and such so I haven't made any progress on the drive section. But I will post pics to follow my progress.

@Technopro - here is a very rough drawing of what this bot will look like.

Can't wait to see it come alive

Got my targeting laser finished last night, just need to install it in the dome. I will also install 3 equidistant motion detectors.
#32  
Been working on the airsoft guns. I tried using the guns I got from Josh Starnes but I ruined them. So I had to go with a different gun.

I settled on these Uzi's. They are more compact, run on 7.2 volts, have a higher FPS and their boxy design make them ideal for making mounts.

First I had to cut the handles down.

Then I made aluminum mounts to tie them together.

And this is rough idea of what this will look like mounted on Grilller.
