OCR Working Better

Got the OCR service mostly done last night and today.  Need to get more sleep!  I uploaded new videos of Anna reading words at various distances.

It seems very reliable now with letters that are 2in high at about 6ft away, so I'm think 3-4in high letters in smaller rooms and 5-6 inch letters in larger rooms should be sufficient.

Shout Box talking RPi: Trials and tribulations

A nice perk of LMR is the Shout Box, LMR's own little chat room. Many times I've been struck by motivation to solder/etch/hotglue/bodge something just through the good maker-mind energy in the SB but, alas, I would have to hang up the phone, if you will, if I were to head to the workbench. "Gee," I thought, "wouldn't it be awesome to have the Shout Box read to me so I can laugh and cry and work on a project all at once?" Yes, and it is awesome.

"Do not average your Max-Sonar results..ever!" who knew?

I've apparently been mistreating my MaxSonar EZ-1.   I can't find where i stole.. er... borrowed my idea from for averaging a series of responses to reduce the inconsistencies, but I was looking up some information on the Arduino pulseIN() timeout (Thanks Oddbot!) and came across http://playground.arduino.cc/Main/MaxSonar   ... Yeah... I know it should have been one of my first places to look, but...

My Robot Butler

Not to take users off this site but updating two postings of this is getting tiring. From now on you can find info about this project here. I will leave the funny video up.

Theo Jansen style robot leg: prototype #6

(continued from here)

I am busy with the tweaking and fine tuning of my plywood version of prototype #5. I had no idea this would turn into a different design I now call #6.

This photo shows #6 in its leftmost position. It just cannot reach the extreme. There are still several small bits of plywood touching that should not be touching. Again with the jig and with the saw!

 

XMOS Challenge : ONR robot beginnings

Description of the ONR (maybe a real name TBA)

This robot is to navigate outdoors from point to point, possibly going through a series of predetermined points. Point location can be marked by traffic cones, GPS coordinates, or other orienteering markers as detailed in various contests like Robomagellan or the DPRG outdoor contests.  Requirements include finding and recognizing the point, as well as negotiating any obstacles between points, and maintaining a remote stop.

Control Picaxe with computer

I've managed to control my picaxe with my computer and thus with another picaxe microcontroller (which I'll need in a project later on)...

 

 

WCRG 2010 Pictures and video

B5 progress

Whatup gays,

Calculon just wanted to drop a line and share his progess on his B5 (the Backyard Beverage Buddy BBot) project. He started his project last fall as his entry into the XMOS challenge. The idea is basically a cooler on wheels that rolls around Caluclon's backyard and offers beverages to people. That's still the general plan, but the scope has changed slightly.

B5 1.0 features the following:

Scaling down a boat to make USV

I have been dealing with asects of theis for a while and this is my latest idea. Build a small plywood boat downsized to be a platform for robotics testing. I bought a "partially built kit" on eBay that turned out to be an abandoned upgrade of a hobby grade boat. It's a 15" V narrow plastic V-Hull and I am concerned about it being to close to max with a decent battery and gear in it. But the upgrade in process inculded a good servo steered rudder and through hull prop hardware. The supplied motor is marginal but workable. I have a brushed ESC with 5v BEC.

Lunar Rover

Hi all,

Just want to share some videos of a moon rover study I am doing for the Google Lunar X Prize. No time now to submit a robot project entry, the rover is quite complex, maybe later. I'll add videos here as they come along. Thanks for watching.

 

Bluetooth control from your Android phone or tablet

Hello, I am the author of Mintoris Basic for Android phones and tablets.  I recently added Bluetooth serial communications to the language with the intention of making it very easy to communicate and control robots.

Here is a short example program in Mintoris Basic which connects to a device then transmits data from the phones accelerometer.  So as you tilt the phone or tablet in any direction, the amount of tilt is sent to the Bluetooth device.

dim a$(0)
dim c(4)

' Get a string array of all the paired Bluetooth devices

a$()=BTGetPaired$()

WiiCamera Break Out Fail (Not my fault)

It seems that God is not without a sense of humor...

So, I had a bit of a run there for a while of producing boards which later became coasters. Bound and determined to not let that happen again, I set out to design my WiiCamera break out boards. I carefully layed out the circuit, breadboarded each and every part, and then designed a neat, simple PCB around the breadboard circuit.
