Modular humioniod robotics? Answered

Hello my name is Alex, I have a very early stage idea for a modular humioniod robotic development platform. I'm looking for information, a point in the right direction to all things modular robotics. Books, threads,forums, drunken scribblings on a napkin I don't mind. What I would really like to do is a open source collaboration, where people can make either the whole thing or just indavidual modules. What do you think? Great idea? Dumb? Totally unachievable? All comments and replays welcome, positive or negative Thanks in advance Alex

Modular Lighting - help please!

Hullo! For my school project, I am manufacturing a modular lighting unit but I'm a bit lost on the whole electronic side of it. Basically, I can make anything as long as it's vaguely connected to the theme "modular lighting". At the mo, the idea I'm continuing with is flowers in a vase - the flowers are the light source and when it is stuck into the vase, it recharges. I've never done anything remotely related to electronics before so any help as to how I would make this is welcome! :) [or any new ideas] I would just buy a charger to make it easier for me, but I don't know whether I can buy one where, instead of inserting the batteries in, there's wires coming out? Almost like a phone charger or something, so I can connect it to the vase somehow. Thanks!

Is it ok to post it?

Hey Instructables! So a couple of weeks ago I finished a year long project, automating my room. The project is completly modular so if any piece burns out or fails you can quickly switch it, the project includes automatic lighting controlled via a PIR sensor, an LM35 controlled fan, a miniature green house controlled by another LM35 and it displays the info about humidity and temp, through a 16x2 lcd and DHT11, a combination lock for my door via a keypad, a infrared control that can turn on or of my desk lamp, alarm clock, room lights, solder station and has the function to turn the whole system on or off, it also includes a modified Sony alarm clock, that has a TDA2040 amplifier with aux in and its connected to some speakers around my room. I have all the eagle files and ready to print pdf´s. Everything is controlled by 2 DIY arduinos. I made most of the modules for the sensor array but a couple of the controll modules were made using already existing files on fritzing, and the DIY-Duino Should I redesign this modules and controller board before uploading, or will crediting the authors of this parts will do?

What is a good cable/socket system for modular circuits?

I've been working on and off on an integrated color organ and vumeter over the past few months.  Part of the design is that there will be a central "hub" that will do all the filtering and user interfacing, allowing me to build the display itself separately.  The intent is that this will allow me more design freedom in a display, since I won't have to fit all the circuitry into it.  It's also cool, since this project is more self education than anything else.  The minor problem is that I have no idea what type of cable or connector to use in order to make the design modular. So, is there a good cable/socket type for this purpose?  It preferably needs at least five wires (high, low, mid, left channel, right channel), which is why I don't think USB is a possibility.  Also, will it be necessary for one of the wires to be hooked up to ground of the central hub?  My intent is for the display and hub to have different power supplies, with the filter outputs hooked up to transistors in the display, which will in turn "trigger" the leds. Forgive me if this is a glaringly obvious question; I'm entirely new to electronics, so I have no experience with cables and the like. edit: the display is going to be at least a foot from the central hub, if not more, so ribbon cables and the likes are out of the picture.

Modular Furniture Parts (or Legos for Adults)

I've been considering building more flat pack furniture (I'm sick of moving around awkward cheap crap made of MDF or particle board) and I've been thinking of maybe making some kind of modular parts that could be configured in different ways to become different pieces of furniture. Does anyone know if such a thing already exists? Also one of my sketches involved building frames out of posts and cross pieces with some surfaces built from strips of wood suspended on metal rods. I was wondering about the feasibility of making something like that. I realize I'm sort of babbling here so I'm attaching an image from my sketches. Does this make any sense? What could these supports be made of? Originally I liked the idea of using metal for the contrast in materials, but I don't have a metal shop and I think getting them fabricated would be expensive. If anyone has any input, let me know. It would be cool to have an open source modular furniture system (well I think so).

Is it possible to make modern looking, cubby style storage out of cat litter pails? Perhaps modular? Answered

Depending on the brand of cat litter, the pails seem very well-suited for being made into stacked, modular storage.  They are so sturdy but cannot be recycled in most areas. It would be ideal not to have to cut off anything, but the edge where the pail is intially sealed prevents the pail from laying level.  Could something as simple as  2" x 4"s help stabilize them?  But would that necessitate an overall structure or lattice holding all the pails together? (Disclaimer: I don't use clay cat litters because of environmental concerns).  And, if the lids could be included in a design, it would be a great way to store all kinds of supplies without dust getting inside.

Proposal for a Multitasking Robot

Greetings, I am a senior EE major at Polytechnic University. I spent most of my time working with robotics and electronics. I always wanted to enter one of these robots competitions but finding the time and funds was always the problem. Its really interesting that iRobot is deciding to sponser a few teams. After brainstorming I came up with a few robot ideas that I believed novel. Then I thought about it some more and came up with more ideas. Instead of narrowing them down I thought how great would it be if all of them could be made. That led me into designing an idea for an iRobot Butler that can do many tasks. The idea is to create a modular robot that has the ability to dock with its base station and perform multiple tasks with different specialized modules. The project I propose is to develop the modular autonomous docking system and several modular tools for the robot to utilize. These tools can be used for entertainment purposes or for human aid. Here are a few concepts 1) Mobile Music docking station and amplifier - You have a stereo system, great! Only down side is its always stationary so you have to blast it till the neighbors know the lyrics if you want to hear it everywhere in the house. With this kind of a docking station just come home plug it in and let the music follow you. 2) IRobot key fob (that thing that opens your car) - Why have robot if you can't command it when you need it. With a IRobot linked to some off the shelf electronics you could have it meet you in whatever room you are in. 3) Where's the remote? Who knows? But iRobot can help you out by using a embedded universal remote following the sony ir protocol. Just give iRobot a buzz and he could come in and change it to your liking. 4) Not so Clocky Alarm Clock - Clocky is a robotic alarm clock. It rolls off its nightstand, hides somewhere in the room and then starts to wake you by forcing you to find where it hid. With the modular IRobot when you go to sleep it can hook up with its Music docking station and do pretty much the same thing. 5) Life Alert System - Many of us have been hurt at times where we wished someone could come to our aid. If you are in a accident and unable to reach a phone, press on IRobot's key fob and him lock onto another tool which brings you a cordless phone module to call for aid. The Docking Station The docking station for the robotic butler could be tracked using the same method as the self charging station. In order to remove platforms or add them a servo would be placed on the iRobot which would lock or unlock the tray. To maintain electrical connection between the two trays an array of spring header pins could be used. There are many great robotic ideas out there for the iRobot however the expense for one robot to only do one thing is pretty great. In order to compensate for the overhead expenditure a multifunctional robot with inexpensive and optional tools is a possible solution to suit home needs. This way all of the design entries can be utilized. Regarding my qualifications, I taught for three years as a teaching assistant to a freshman engineering course. My most recent completed project is the development of a chemical model car experiment and an Autonomous Underwater Vehicle design project for freshman engineering. Both of these projects underwent a rigourous amount of work and will be shown at the American Society of Engineering Education 2007 conference.

I've almost finished my M4 SOPMOD. One problem. I need help making a SOPMOD kit. If you want to help, you can be a collaborator in the 'ible.  Also, for my next project, I would like to make an XM29 OICW. I've included a picture for those of you who don't know what that is. I'd like it to be a collaborative project. Hopefully, The top portion would be a repeating mag fed sling (Pseudo-Semi auto?), and the bottom part would be a mag fed repeater (semi auto?). they would be modular, and be able to fire separately. Also, it would be cool if when connected, they both fired with the same trigger.  If pulled off right, this project could be very innovate, and advance knex considerably. That is, if good range could be achieved. Also, it would be an awesome replica. I'm not sure which part I'll do, but it'd be great if some people wanted to be part of it, and if these people had some good ideas for mechs.

How do you finish your projects? Answered

Whenever you want to finish a prototype, what kind of checklist do you go thru? things like: How do you decide what case design to use, what materials for that same case, how to solder everything up, what makes you decide if you "lock" the Arduino on that project forever by soldering everything around it. If you decide to make it modular, what techniques do yo use. What kind of material do you use to attach everything together: Hot glue? close everything down with screws, nails,  staples (...)? How would you make it water-proof or resistant to the weather (if it was something to be outside for a long time). If you have to use a lot of cable, do you solder everything up with heat shrink tubing? When do you use connectors and what kind of connecters do you use? I would love to see a video tutorial on how to properly finish up a project, and make it look beautiful inside a case.
