 :) hello!
Looks like you have a design, above the amateur robotics range.
For industrial parts, check out a book called the Thomas registry. It lists
all the manufacturers in North America. It sounds like a job for multiple
contractors, if speed is needed to get you up and running.
Software simulation, use Mathematica or Autodesk. (alot more are avaliable)
The manipulation of liquids at 110 C (= 230 F) sound like a quesiton for
Perry's chemical engineering handbook. This would be a guide for your begining
of the materials, and may help in collateral questions you would have later on.
Precision of +/- .5mm (.0196 inches, or roughly 20 thousands) would not be hard to
make on a Smithy lathe, or southbend lathe. if you wish to make things yourself.
Software for your controller can run anywhere from an Allen Bradley PLC, to more simple
robotic microcontrollers, depending on application. Simpler control, with no deadline to achieve
results, indicate a smaller cost effective microntroller platform. If more demands are projected,
more money vs project demands must be calculated. Good luck!

Mechanics and Construction / Re: Need help with a project!

Cool! Maybe I can offer an opinion......
Are you using wheels, the demand will be different from a walking model.
IF YOU ARE making a walking model, I would offer an idea in that direction. I have
been working on an inexpensive way for robots to walk, and does not require
a million dollars to program. Still in the proto stage myself.
I have found out that, the wheeled robots are easier to program than the
walking ones, with balance and direction to take into consideration.
The walking structure that I use is simple(relative), and less expensive. I designed it
to do work, in the expectations of a human counterpart. With simplicity, comes less
programming headaches. --

Mechanics and Construction / Re: robot motor question.

Hello! I can offer my opinion.
I would look at the terrain that the robot has to go. (load conditions)
Hydraulic motors can produce power to the wheel, but too heavy.(smaller, maybe?)
This sound similar to a chemical engineering question, with the power/ load demand.
You could take a motor, then run it in place on a jig & fixture, to determine the total
power demand per m. Or, run the whole model on a jig and fixture to get an idea
of the power consumption.(with load). You could use the Jig & fixture to give a laboratory
guesstimation of what would be needed, as a model. You could then, "tweek" out any
mechanical designs that you have, or mods to the UGV. If you are at a university, the neighboring
students at the electrical department may offer more insight, as they are on sight. Good luck!  :)

Misc / what types of microcontrollers do you use for your robot?
« Last post by mklrobo on January 21, 2015, 10:12:11 AM »
 :D  Hello! I am new to this forum, and would like to ask a question.
What kind of microcontroller do you use for your robot, and what advantages does it offer?
I was reviewing Axon, and it has alot of features that I would like to use for my "future" robot.
There are alot of products that I have looked for, but could not fine until I went to this forum.
Parallax provides the propeller microcontroller. Have not used any adunio products. Thank you
for your direction.  :)

Software / Re: How do you program a rubiks cube algorithm?
« Last post by mklrobo on January 21, 2015, 10:05:14 AM »
I forgot to add that I did find a program that solved it, and put the coordinates in a
file; the positions were listed in the vanacular of the program itself. That would have to
be interpreted and interfaced to the robot.

Software / Re: How do you program a rubiks cube algorithm?
« Last post by mklrobo on January 21, 2015, 07:20:28 AM »
Hello! I have a suggestion. (I was on my way to do this myself)
I started to use a method like Awally88.
You can aquire a free "digital" cube solving software on the internet.
Then, the work begins.
I tried to find color sensors, and match them up to the emplacment on the cube.
In parallel, program the digital cube in the software to the same color/state emplacement.
Program the digital cube to step though the solution; in each step, program the robot
to move the real cube accordingly. Thus, the cube will be solved for you, with little or no
headaches involved.
       The trick is, of course, to interface the software. That is where the work will be. Making your
own systems of equations to solve the cube will be a JOB.  I wanted to rent my cube solving robot to
a near circus, for amusement, but no one wanted to entertain the idea. Good luck with your project! :)

Important dates:

Application deadline: January, 27th 2015 (Extended)
Notification of acceptance: February, 7th 2015
Event Date: March 18-22, 2015.
Location: Peccioli (Pisa), Italy, http://www.echord.eu/facilities-rifs/the-peccioli-rif/
 
Website: http://www.dis.uniroma1.it/~rockin/


RoCKIn is short for "Robot Competitions Kick Innovation in Cognitive Systems and Robotics" (http://rockinrobotchallenge.eu) and it is an EU-funded Coordination Action aimed at the promotion of research and education through competitions.

The RoCKIn Camp 2015 aims at leveraging the preparation of teams to participate in the RoCKIn@Home and RoCKIn@Work challenges, the competition event that will be organized by RoCKIn in Lisbon 2015. RoCKIn@Home and RoCKIn@Work take inspiration from the corresponding RoboCup leagues, but they focus on benchmarking robotic systems and networked robots. Both challenges require basic navigation capabilities with no restrictions on the mobile platform, advance perception, manipulation and human-robot interaction. RoCKIn@Home focuses on tasks that service robots execute in a real home environment, while the tasks to be performed in RoCKIn@Work target an industrial automation scenario.

The RoCKIn Camp 2015 will take place from 18th to 22nd March in the ECHORD++ facility of Peccioli (Italy) and it is designed as a hands-on week long school, where teams improve the performance of their systems through working sessions in the RoCKIn competition tasks and functional benchmarks. At the Camp site, a realistic environment for both competitions will be provided by relying on the existing ECHORD++ testbeds and equipped with the RoCKIn ground truth system for logging data and create benchmarks. The activities planned correspond to the Tasks and Functional Benchmarks as defined in RoCKIn (http://rm.isr.ist.utl.pt/projects/rockin-competitions-wiki/wiki).

As outcomes of the field exercise, we plan to collect the best technical and scientific contributions achieved through the experimental evaluation performed at the Camp in the task and benchmarks into a Special Issue of a scientific Journal.

In addition to the teams selected after the RoCKIn 2014 competition event, the RoCKIn Camp 2015 is open to additional participation of European teams. We accept applications in two formats:
Team applications (for teams with an already established record). Team applicants must bring their robot to be used in the practical activities.
Individual applications by team members.

All successful applicants (individuals and team members) will be offered:
Accommodation in shared rooms (including breakfast, 5 nights)
Lunch (5 days) and social event
Access to the testing facilities arranged for the RoCKIN@Home and RoCKIn@Work

Each selected team will be allowed up to four team members and will be awarded a travel support up to 1200 Euros.

Applications should be submitted via http://www.dis.uniroma1.it/rockin by January 27 2015. The applications should include a technical report including team description (including previous experience, role and competence of team members) and a detailed technical presentation of the proposed solution for the task or functional benchmark to be addressed during the camp. Applications may address one or more tasks or functional benchmarks. The selection will be based on the team submission material and, in particular, on the quality and maturity of the technical solutions proposed for the RoCKIn task and functional benchmarks.

Electronics / Re: Electric bicycle
« Last post by bdeuell on January 20, 2015, 09:13:41 PM »
If I am reading your post correctly you are making a significant error in your calculation. It appears you are using the static radial force on your rear tire, when you should be using the tangential force (under dynamic conditions) to calculate the required torque.

This tutorial might help explain the correct torque calculation.

Electronics / 50$ dollar robot tutorial help!
« Last post by cardboard bot on January 20, 2015, 07:17:38 PM »
Hey guys I'm new to robotics and electronics in general so I'm lost here i started to build the circuit for the fifty dollar robot and stopped after i read (read this post) link about the 6 pin vs 10 pin programmer cable after much speculation of what i had i came to the conclusion that the AVR pocket programmer cable has both if I'm right. but then another thought came into my head after i followed the (read post) link i followed the link provided by supreme robot to download the zip Webbot provided for a simpler schematic when i opened it, it seems to me like the schematic is for users using the 9V and 4.8 battery pack option and therefore being a noob at this i don't know which schematic to follow since I'm using the 6V rechargeable battery, does this option affect the circuit wiring i compared the admin pictures and the pdf diagram and they don't match to me, i would think that this battery option wouldn't change the connections but now I'm having second thoughts. could someone in the same AVR pocket and 6V rechargeable boat answer me on what they did. I'm thinking that i should solder 2x3 pins for the input since the programmer i believe has both and this input/output was said to be newer and then to just follow the admin tutorial since there using a 6V and only one battery. :o :-\
