Sortarm Project Log #1

July 22nd, 2010

Okay, been a while since my last update so it’s arm project time!
So what is “Sortarm”, eh?  Well, it’s my project to build and develop a color object sorting robotic arm.

As you can see I’m already prototyping with the mbed. I’ve chosen this micro because of it’s great features that are stuffed in a tiny package. It has everything you’d expect on a 32bit development platform, but the features I would like to mention are 6 separate pwm outputs, a serial terminal over usb (on the same mini usb jack you see in that picture that is used for programing), ethernet pins that only require you to connect an RJ45 socket with (or without) magnetics directly to the uC and you a get internet connection.


I’m currently finishing with the CAD designs for the structual parts of the arm, also did some pcb design for a pwm brakeout board which also will have to be fabricated soon (I have quite a few boards needed to be done over this long time).
To tell the truth, this whole project was delayed tremendously by our countries postal offices. The order from sparkfun was delayed because they didn’t manage to find the invoice. I had to contact sparkfun, get a copy of the invoice, send it to the post office and then after weeks of delays I finally got it. But the order from robotshop.ca for the servo hinges is already a month late and I still haven’t got any notice from anyone. GODDOMMIT.


And lastly a question for the Lithuanian readers: Anyone know a laser cutting company that is willing to do small jobs like this?
