What type/shape of metal ( i.e. tubular aluminum) should I use for a robot frame? Answered

I am building a robot. It will be about 1.5 meters long, about 30 centimeters high, about 40 centimeters wide ( all dimensions excluding wheels, tracks, etc.). It's body will be a metal frame with an outer fiberglass shell. The frame needs to be strong, lightweight, and rugged. It would also be nice if the frame could be welded with a homade stick welder, but that isn't a primary concern. Any advice is appreciated. Thanks!

DIY Storable Tubular Extendable Member (Tape Measure Style Extendable Robot Arm)

Hello, I am on an FTC robotics team, and often robots are required to lift/reach objects. This year, a challenge was to reach up and grab onto a pullup bar; the robot then completed a pullup. One common method this year was to use a tape measure; the tape measure was unwound using a motor, remained rigid due to standout, and was then wound up, lifting the robot in the process.  I am now in the offseason and I want to improve on this design. I found that a very similar mechanism to the tape measure has been used for extendable antennas on spacecraft. I would like to create a similar mechanism. The main difference between the tape measure and the STEM mechanism is that the STEM extends a tube. The tube is rolled from a sprung piece of metal. The piece that I am looking for is a material that could be flattened, but would retain its tubular shape like on the STEM. Does anyone know of any types of pipe or tubing that could be cut lengthwise and possess this springy characteristic? Is there anyway to create a material like this? Thanks, icecats

DarkOwlKnex's Project Update Five

As of late, I have been modding Bijou, my magical rifle, and making Short Deluxe Extended Playtime Albums for certain characters.   (You can see the four original Homestuck Kids' soundtracks here.  Don't fret, you don't have to be a fan of Homestuck to enjoy the albums; in my opinion, it's good music, and as the albums are based on a certain character, they are based on a theme to some extent.) (There is going to be soundtracks for the ponies from My Little Pony; Dr. Richtofen and I have been collaborating on what songs to pick.) In addition to those two things, I have been working on a new pistol, that I'm going to call Insight.  It is a super compact pistol that is different from all others because of one thing: it has a tubular magazine.  To my knowledge, it's the most compact tubular magazine gun to date.  The pictures show the gun and how to load it. Insight also: Shoots green rods. (A downside for some, but a pro for others). Uses a red rod sized firing pin. Has a comfortable handle. Can hold up to five bullets at a time. Gets about 25 feet as of now.  (This is just the pre-beta version, so I will keep modding it until it goes farther) Requires no cut pieces. (Nor do any of my posted guns, come to think of it.) And... Yes, the gun has a theme song: Insight by Joy Division. That's pretty much it. DarkOwl Out...    ,     ,  (O,O) <(IIIII)>    I    I

Insight 2.0

I know what you're thinking: I'm not allowed to make guns anymore.  Well, you're right: I'm not.  This video was recorded entirely in secret.  My school has had some weird days off so people can take the ACT and all that nonsense, leaving me home alone.  I'd say a pretty great thing came out of it: Insight 2.0.  A huge improvement from version one, this gun now has a sliding trigger, its coolest feature, a realistically slanted handle, an even comfier handle, and a much more reliable tubular magazine.  I hope you guys enjoy!

MIT team designs plane that uses 70% less fuel

Planes use a massive amount of fuel to move passengers and cargo around the world. A new design from an MIT team could cut this fuel usage by 70%. This is great news and would make flights cheaper and pump out a lot less carbon. The bad news is that air traffic is expected to double in the next 30 years and the earliest these designs would be in the air is 2035. MIT designed their D-series as a 180 passenger aircraft meant to replace the domestic 737 market. Conventional airplanes utilize a single fuselage design, while the D-series uses two partial tubular shapes placed beside each other — which accounts for the bubble nickname. The plane utilizes a host of technological advances to decrease its fuel consumption. It has thinner longer wings and a smaller tail and engine placement at the rear of the plane instead of on the wings. All of these features account for part of the reduction in fuel usage.

Ring a bell? (Special event for British members)

The Olympics are coming, and although I will miss most of it, it would be cool if I could take part in some way. It turns out I can, and so can every other Brit reading this, in an event called All the Bells. The short version is, on Friday 27th July, at 08:12am, UK time, as many bells as possible, from doorbells and bike bells, all the way up to full cathedral bell-towers will ring, all across the United Kingdom. Taking part is easy - just stand on your doorstep and press your doorbell - but why not go the full hog?  Are you in a cycling club?  Get them all out in the street, ringing their bike bells. Live near a church?  Even if you're not religious, get in touch and get them involved. Go to school?  Talk to the music teacher, borrow the hand bells or the tubular bells. Are you an engineer?  Hang up the biggest lump of steel on the site, and beat it with a hammer. Heck, just get all your friends to set an alarm on their phones and iPods with a bell-tone at 08:12, or turn up your PC speakers and play with sound effects. Pass the website around your friends and contacts by Facebook or Twitter, put a poster up at work, add graphics and links to your blog, and generally spread the word. [BLOGGED]

How to add suspension to a food trolley to prevent spillage of food and tea?

I am an A level Product design student and I am designing a food trolley for a person with grip and stability issues.  One of the biggest problems with current models is that when they go over the slightest bump or carpet runners/plates e.g. and they will spill and tip whatever is on them. This is a massive problem if the user is carrying hot tea or their dinner, increasing clean up work and generally reducing the quality of life of the user. I cannot think of a relevant method for stabilising the food tray/drink holder without drastically reducing the overall function and massively increasing cost while still allowing the trolley to support the user while they take their food from the prep area/kitchen to the eating area.  A few Ideas I have had:  large pneumatic wheels (solid rubber in most other examples), Some sort of spring suspension, Pistons, A counter weight... I have tried researching stabilisers for cameras but they don't seem to be relevant. Help with research keywords would also be useful as its difficult to know what to look up. Another problem I'm addressing is the aesthetics of the product as most examples just look like hospital equipment not everyday furniture. Currently I am siding on wood as the main material for the frame, If anybody has suggestions that would be better than boring tubular steel I am still in the early stages of development and would appreciate inspiration!

Ideas for making simple LED Flashlights, about 6 inches long?

I am wanting to create several (about 20) custom LED flashlights that could be attached to key rings. They would need to be long and tubular in shape, about 6" long, and with a button switch on the back so that the LED is lit when the button is pressed and held, and turns off when the button is released. This would be so you could blink the LED easily on and off manually; like if you used it to send a Morse code signal with the light. Battery powered; most batteries like coin batteries or up to a AA would be fine with me, as those will all fit easily in size. I plan to create the body of the flashlight out of polymer clay or another durable craft material. It would be a unique shape: a column made of colorful geometric forms. The inside could be made cylindrical to better fit the battery and other innards, though. The chapstick flashlight seems to be the closest thing to my purpose here; I am just unsure of how to extend that concept in length to be the same diameter but a few inches longer since the chapstick was the length of the battery! I've also considered buying an LED flashlight or two and taking it apart to see if the insides of it can fit inside a longer flashlight body (maybe it just would need extending of some wires? I don't know). I've been reading up on the LED instructables here. I've never soldered or built a circuit, but I am ready to learn! Any ideas you could share would be very helpful. Looking to get these made this month for an event. I am a technology-building beginner here, so speak slowly!
