I'm trying to find some solution for an articulating arm to go into an LED lamp project. I'd like either something cheap or something I can build, but so far I haven't had much luck. I could always dismantle an existing lamp, but it sort of defeats the purpose to buy a working lamp and take it apart to make another lamp. Any suggestions?

A while back i saw an instructable that was a wooden robot arm it had a main arm and a second smaller one. the smaller one had a handle that allowed you to move it. you moved the smaller arm to program the larger one. anybody know what i am talking about?

In Science next term, we've been told that we'll need to build a robotic gripper. All it has to do is pick up a cup. I've been having a look around, and the balloon idea isn't practical because if the cup was full it wouldn't work. And I'm okay with spending a little money, but I'd rather not spend $100 or anything on a kit. So what's a good idea for me?

Will someone write up the plans for a HEAVY-DUTY ankle and wrist weight. I have been searching online for a company that will make custom weighted wrist and ankle weights but there aren't any. I'm wanting to make a 50 lb for the arms and 100 lb for the legs. I'm thinking along the lines of several iron or lead bars strapped together with a nylon fiber or other strong material. I've only ever done projects in high-school, where materials were provided, so I don't really know where to get the materials needed. Please help.

I'm looking to make a flexible arm that I can position however I want. I need it to have a fair bit of holding strength in that I don't want it to sag. It doesn't need to hold my body weight or anything like that and it can vibrate or move a little without being a problem. Immediately, two things come to mind: the plastic pieces used for coolant in machine shops that has now become a common material for something like this. The other is made up of stacked plates with a ball on one side and a socket in the other, I wire or something of the sort is put through it and a tensioning knob is used to pull it tight and keep it in place. Commonly, I see these in mag base indicators. I'd prefer to find the second one. Though, I can't seem to figure out what to look for in order to make my own. The best thing would be to find a modular kit that would allow you to make one fo any length (I need one that is about twice as long as a mag base indicator mount). Any thoughts on what or look for or anyone know where you could find something like this? P.s. this is going to be used as a way to hold a small screen. If it works well, I may adapt it to work for other things.

Hi, I am building a 6DOF robotic arm for my final school project and i need you help I have an arduino and i have to run 6 servos with it i have a joystick shield on my arduino and was wondering what the best way to power the servos is. Should i get a servo shield, or seperate board? Also i have a 360º servo in the base and when it spins left it instantly stops when i let go of the joystick but when turning right it does stop but it stops smooth. I thank any help you can give me and english is not my first language. PS.: if you want i can send pictures.
Question by Miguelc1 | last reply
Having finished my rifle and finding myself with nothing to do ( Don't worry, it will still be posted this week ), I thought I'd finally have a go at side-arms. So I built the TDS2, and hated it ( I'm going to get bashed for that, I know it ). I decided to have a look at some others like Oompa-Loompa's unofficial side-arm, and the one Bakenbitz posted a picture of on KI some time ago. Afterwards, I came up with this. This side-arm is powerful because the magazine is at the front and the trigger is at the very back. It's also kept reasonably small because the magazine is inside the handle.It fires grey connectors. It's a bit clumsy, but it is only a first version. I can probably make it a bit smaller and more user friendly if I remake it. Tell me what you think, and as always, constructive criticism is more then welcome

I am not exactly sure where to ask this. I have about a 3-4 foot articulating camera arm, which I use for a completely different purpose (medical related). It is great at what it does, except it is very difficult to precisely adjust it. I have not seen anything that will do exactly what I need, but it would look somewhat similar to that type of articulating arm. It would need to have two telescopic sections plus one or two articulating joints. I think I would need to find each of those sections separately and then put them together myself, because I have not seen arm with that precise configuration of sections, and that is as lightweight as what I need. Where should I look for such kinds of parts?

I am building the robot below for a Halloween costume. I am building the head, upper and lower body, arms, and shoes out of silver painted cardboard. But as for the arms and legs I need advice as to what to use. I know the material used in these pics has a name but I am clueless as to where to find them and what it called. The costume should be flexible enough to dance (AKA wave my arms in a worm-like motion) at a Halloween party. Any tips or ideas? Thanks in advance. If you want I'll make an instructable once I figure it out and build it if you ask. PS I am 5 feet 8 inches, and My arms are not too fat or too thin, and I am 14 years of age if you care.

I recently had a great idea for a completely useless, yet hilarious project for me to work on, but I am stuck on a single piece.The end result is a joke device that uses one of those accordion, spring loaded boxing gloves controlled over USB (the idea came about in a discussion over the universal wish to punch idiots over TCP/IP). To understand what this is, you'll have to think slapstick comedy and saturday morning cartoons (of the Wile E. Coyote variety). It sort of looks like this but replace the lamb with a boxing glove, and when extended looks like this: XXXXXXXX. Imagine the coyote opening a door that he expects the Road Runner to be behind, and out pops a boxing glove on an accordion arm that hits him in the face, making those little roadrunners circle his head.I suppose I could make one out of some material (metal, plastic, wood?) but I don't have much in the way of fabrication facilities in my new apartment. The best outcome would be if I could get such an arm off of an existing device.Sure other things could work (a piston for example), but the look of this project is very important and an accordion arm is a requirement to that end.Any idea on how to go about building/obtaining such a thing? I can't even figure out what to use as search terms.

I have an antique platform rocker that I need a replacement part for. It is a cast iron arm at each end of a wood spindle. Looking up online I found it may be called the "Lowentraut mechanism" and was designed in the late 1800's. The rocker I have is in good shape but only has one of these cast iron arms and I am trying to find a way to get a 2nd one to complete the rocker and refinish it. I am attaching a photo of the one arm that is on the rocker. Any information on how to find a replacment part would be appreciated.

From The Design Blog, via NOTCOT: Pushing the boundaries of current upper-limb prosthetic design, designer Kaylene Kau has created a prosthetic arm that supports the dominant functioning hand in accomplishing day-to-day tasks with ease and efficiency. Featuring a flexible design, the prosthetic arm adjusts to allow a variety of different grips to hold a variety of objects with minimum fuss. The Prosthetic Arm also integrates motors and cables, which help the user control the amount of arm curls required for different tasks. Presenting a simple yet effective design, the new prosthetic limb makes users self-reliant, as they can carry out their everyday tasks without any assistance. Of course, any advances in prosthetics is welcome, but I bet the first thoughts of most people reading this here were either Cool! I could be an octopus! or Woah - I want one of those on my next Hallowe'en costume! I'd really like to see a video of it in action - I can't decide if it would be cool or creepy. I also imagine that an arm like this would be (relatively) easy to engineer for the amateur.

The veins in my arms (a ton in my right, a lot, but not as much, in my left) bulge a ton, even if I'm not doing anything. While typing at a desk they look fine. Just sometimes out of knowwhere they just bulge, I might not even be doing anything that requires effort!. Is this bad? It doesn't hurt, it just looks weird. I don't work out (mind you I'm not that weak either, I'd call myself average), I weight about 100 pounds (I know, I'm light), I'm ~5' 4", and I'm 14., and I'm skinny. I'm Eurasian (half korean, and half white stuff like german and welsh, etc.). I find this really weird cause 2 of my friends are really strong, but they don't have the weird vein thing (they're skinny too). My arms are pretty thin, like I can wrap my thumb to my middle finger around my arm (about halfway inbetween my wrist and elbow, maybe a little more) More that I think about it typing bulges my veins, I'll post pictures of my right arm soon, it's freaking me out. Soome kids in my school are like "cool, how do you do that." Some girls are like "eewwwww" when they see my arms, but other don't seem to notice it. Bottom line, is this good, bad, should I be concerned, etc.

I love steampunk aesthetics, in both machines and clothing (I'm meaning girls) branches... but I have no artistic talent at all, so I can't develop such a beautiful machines or decorations. But sometimes steampunk fans care a lot about clothes and less about characters. They simply dress up, and waste the chance to assume a character, especially at conventions and meetings. There are lots of steampunk prosthetic-mechanical arms and hands, but I can't avoid think about "less are more". I mean, a mechanical arm in brass, cooper and leather talks about your wit and ability, but a (simple) wired frame UNDER the jacket, apparent only by bumps and tensions under the sleeve and glove, and even better with mechanical wishpers and quiet pneumatic sounds when it moves (if you are so gifted), tells a story about the character of your character (if you understand me): for example, an inventor who has lost the use of an arm, may try to recover it and keep it hidden, like a shame. You can link it with an accident, a tragedy, a heroic act or a sacrifice. It would be part of my character, If I would had one. BUT steampunk is all about aesthetic, so... is it a nonsense? Or is it a second-level, deeper dive in the steampunk world?
