Let's Make Robots!

camera vs kinect

Hi, what do you thin is better? Ordinary camera* connected to arduino ( if that is not enough, Rasp Pi will be better? ) or kinect ?

I need that to recognize a object and sending video to the pc or mobile. 

*camera like pixy or something like that :)

Wild Thumper 34:1 slow driving

 I am currently using a 6WD Wild Thumper chassis as an autonomous mapping robot (in progress). I am really struggeling with the PID controller as I often get a humming noise instead of motor turn at low PWM values.

ComMotion Shield for omni and mecanum wheel robots

After building my first omni wheel robot I realized how difficult it can be to monitor 4 encoders and drive 4 motors so I designed the ComMotion shield. As the name suggest the shield is designed for motion control but as I ended up with 2 spare serial ports I decided to add communications abilities to the shield hence the name ComMotion.

Trick switch not working.

I built a trick switch using  Make's basic Arduino Projects bookelt the other day, and I'm running into a problem.

Book Recommendation: "The Peripheral" by William Gibson

I dl'd the eBook version of this to read while recovering from surgery last week and could barely put down the iPad.  It adds makers to the list of hackers that Gibson has been writing his tributes to for the last several years.  I was surprised by how much the idea of 3D printing could become a part of the fabric of a story and have it remain interesting.

Options For a Remote Control T'REX

Dagu's T'REX robot controller has several options for operating the board with a remote control device of some sort.

The program which comes with the T'REX can accept several different remote inputs. These include (but not limited to) Bluetooth and pulse length signals from a RC receiver.

Large robot chassis with 50W MP3 player

Dagu is now selling the chassis for our Venus robot as a separate product for $435 USD.
Please note there is a discount for people who log in and an additional discount for LMR members.

This is an ideal chassis for anyone who wants to make a large butler robot. It is an aluminium chassis with 2x 200mm (8 inch) drive wheels with rubber tires plus 4x caster wheels for stability.

World Maker Faire NY 2015!

June 11, 2015:

I'll be hosting a Google Hangout this evening at 4:00 PM EDT to do some planning for the faire. It will mostly be Rick and I, but anyone is welcome to join and contribute. Reach me on Google+ if you want to be added. (https://plus.google.com/+AndrewTerranova/posts)


Books, Lots of Books


I'm unpacking boxes and replacing the stuff that I'll be keeping from the divorce. That leaves a lot of stuff to get rid of. I have a lot of robotics books that I'll be putting up on the Marketplace.

My question is that I have a ton (or maybe two) of science fiction/fantasy/mystery books. Do you think they would sell here, or should I put them up on EBay?

Many of these are old and aren't available as an ebook yet.

Trex Motor Controller i2c read while using rc

I am starting to put together a rover using Wiild Thumper and the TRex motor controller.

I am having some difficulties getting i2c working reliably from a Raspberry Pi 2 running Ubuntu 14.04

While I am continuing to research my issues (possible future post coming) I decided to give the RC connection a try.

My question is if it is possible to access the i2c read only while using the RC as I would like to try out code for monitoring the current draw and battery voltage.
