Mechanics and Construction / Re: 3D printing parts for fun!
« Last post by Anoroc on August 15, 2014, 08:09:04 AM »
Not a secret. I just didn't want to come off as an advertisement, (I really just want some fun projects to print, and share).

However, since you asked:

We spent about a year refining everything. I'm toying with some other forms of printing now, but it'll be quite some time before I'm finished :P

Misc / Need help with picking a university course!
« Last post by Zevoo on August 14, 2014, 01:14:49 PM »
Hello guys.  :)
I'm applying to universities this year and I want to study robotics. Since this forum is all about robots I thought it's the best to ask people here because they have got the knowledge of robots and will point me to the best university courses.

In more detail, I'm interested in creating robots and research. From the parts of a robot to the programming. Basically I like to see my self as a inventor.

I have prepared a list of the courses. could you guys list top 5 in order of the best to the least best. Top 5 because I'm only allowed to apply to 5 universities through a website called UCAS. Judge by quality of the course and not the university!  :)

Here are the links to the courses:
http://www.kcl.ac.uk/prospectus/undergraduate/programmes/alpha/PQR/keyword/robotics = king's college

http://www.mdx.ac.uk/courses/undergraduate/design-engineering-robotics = middlesex uni

http://courses.aber.ac.uk/undergraduate/artificial-intelligence-robotics-degree-work-experience/ = aberysywth uni

http://courses.aber.ac.uk/undergraduate/astrophysics-masters-degree/ = aberysywth (also came up when i typed in robotics)

http://www.beds.ac.uk/howtoapply/courses/undergraduate/next-year/artificial-intelligence-and-robotics#tab-6 = uni of bedfordshire

/www.reading.ac.uk/Study/ug/RoboticsMEng.aspx = uni of reading

http://www.reading.ac.uk/Study/ug/RoboticsBSc.aspx = uni of reading

http://www.reading.ac.uk/Study/ug/RoboticsIndustryBSc.aspx = uni of reading (BSC Robotics (1 industrial year)  AAC/ABB)

Thank you very much for going through the effort of reading through all the courses, I appreciate it.   :D

Mechanics and Construction / [advertisement] NEW Channel Snap Mounts!
« Last post by ServoCity on August 14, 2014, 12:42:30 PM »
The Channel Snap Mount A provides a quick and simple way to attach various Actobotics parts to your structure. Simply snap the mount onto our aluminum channel as shown below - it’s that easy! Made from 1/8” thick Delrin, the mounts are both lightweight and very sturdy. By incorporating our 0.770” hole pattern they are extremely versatile and allow for a 1/2” flanged ball bearing to press fit into the center hole. The smaller mounting holes are 6-32 thru holes that offer countless mounting configurations. Sold in pairs.

The 9V Battery Channel Snap Mount makes it easy to mount a standard 9V battery into our aluminum channel. Simply snap the mount into the channel as shown below and press-fit in your 9V battery. The mounts will securely hold the battery in place and provide a clean mounting solution - no more tape! Made from 1/8” thick Delrin, the mounts are both lightweight and very sturdy.

I virtually print something every day. I have CNC machines too, but there are some parts that make more sense to create on the 3D printers. It's changed the way I make stuff.

You keeping your version a secret?

Let's see a link.

Mine was a ton of work as all SW is 100% from scratch, both in the uC(ARM7) and the PC.
All axis's servo control (encoder feedback with PID @1kHz update) with brushed DC motors.
All electronics hand designed and built.
Mechanics machined and welded at home.
I did leverage previous work on 3D printers by using store bought hot-bed and nozzle (J-Head).

For total effort:
10% HW
10% Electronics
80% Software

If I had to do it again, I would certainly be smarter about it and use the stepper systems that have become common and a motion system like Mach3.

Looks like one heck of a substantial build!

Misc / Just saying Hi from SC
« Last post by Andakwa on August 13, 2014, 10:28:33 PM »
Hello everyone, I fiddle with micro-controllers & electronics and just finished my first robot. It is made with Arduino Uno, Seeed Motor Shield v2, Ping Ultrasonic Sensor, PIR Motion Sensor & a Bluetooth Slave module.
I got the basic idea from a website and used a few of the same parts but wrote my own code.
He roams aimlessly, pausing to see if my dogs are following the continues on or turns on them if they are stalking him and I can turn him into an RC car via bluetooth.

Nice to meet you all.

If anyone is interested, shoot me a message. I can print with ABS, PLA, PETG and flexible filament.

That's cool you're willing to do this for people.
I made a 3D printer - printed two test pieces - and haven't touched it since.
Turns out that for me, building a 3D printer was the goal, not having one.

Mechanics and Construction / 3D printing parts for fun!
« Last post by Anoroc on August 13, 2014, 12:21:39 PM »
Hi everyone. Since the beginning of the year, I've been developing a 3D printer. We're actually finished with the printer, but I want to start blogging about my experiences with the machine. If anyone has parts they want printed, I'd be happy to print them for free. All I ask is that I have permission to blog about the process and share images of the finished part.

If anyone is interested, shoot me a message. I can print with ABS, PLA, PETG and flexible filament. The available print size is 6 x 6 x 9, but parts can always be broken into pieces, if larger than the available print volume.

Thanks!!
