Web Interface Control: Graphic Design

Here's my initial idea for a web interface for the robot: a 5x5 grid of buttons.

Since the robot is on a truck chassis, there aren't controls for rotating in place, but there are directional buttons for forward, reverse, forward right & left and reversing right and left indicated by the single chevron.

The double chevron indicates faster movement in that direction.

X button in center is all stop/off.

Top row has options for toggling LED lights and an ultrasonic range check.

What Got Me Interested in Robotics

Ok I am an english major who always thought I was hopeless when it came to technology and never expected to actually consider making a robot.

That was before I met my boyfriend who not only writes code for an app company but also recently bought several Arduino kits, couple that with Baymax from Big Hero 6 which got me obsessed with the idea and there really was no other option but to learn how to make my own robot. (plus my boyfirend insisted I learn with him)

Science Fair Experience

 
On Saturday, March 15, I went to the Massachusetts Regional Science Fair. In order to qualify for the state level competition I needed to get top 40 of all the projects.

My Robox is again working!

I finally got around to trying to fix my Bowden tube last week. It had slipped loose from the extruder and was just hanging in space, which made my plastic filament also hang randomly around the back of the machine.

Unfortunately the Robox is a consumer machine which in this case means that the Bowden tube passed through a hole in the wall in the back of the machine that was rather difficult to reach. To make it possible for me to do this, I unhooked the electrical connection for the hot end.

Phase 9 - Web Server Control (cancelled)

Finally, after waiting several months for misc parts to ship from deal extreme, only to be lost in the mail, reshipped, etc..., the parts have arrived I needed to make an arduino web server. The parts arrived damaged, but useable. This is not uncommon for DX.com, so I'm ditching them and looking for other vendors.

Circuit Help

Hello everybody!

I've been browsing the Web for projects using the 555 timer, and found one that interested me: a stun gun. I've been constantly working on the circuit (schematic can be found here). However, getting it work has been impossible for me. For example, according to the description, the transformer alone can produce 1kV, but my multimeter only detects 9VDC, the same as my 9V battery power supply. I even bought a second transformer, just to see if the first one was defective, but still no success.

 

Biped Human Walking Robot

 

Introduction:

A Robot Making a Difference

This is a true story...

My family consists of me, my wife, 2 cats, and 1 robot...Anna.  Lately we seem to learn more and more things from Anna.   Even though Anna is off most of the time, I am often learning and passing on new and useful or interesting things to my wife that I learn from Anna.

trashbot v3: an autonomous spine for the bipedal walker

i've been working on the next evolutionary step of trashbot, a biped robot made from mostly material that i have floating around like bike parts, a typewriter, old PCBs etc. in this version i've added an "inverted" gimbal that is controlled by an MPU6050 and the whole system works as an autonomous spine, counter-balancing the movement of the lower part of the body. 

Depression

Not many people understand chronic depression. I doubt anything I write here will solve anything, but I think it's important that people recognize the signs of depression and learn to recognize them in themselves and their loved ones.

Most people make the mistake of confusing depression with depression. See, I've just done it myself. One problem for English speakers is that the word for depression (as in a chronic life-threatening mental illness, most often inherited) with depression (as in being sad for a few weeks due to a known cause).

Insectbot Hexa

Later than expected but finally finished. The Insectbot Hexa is an advanced offspring of the already aging Insectbot Mini. Build with parts of dead insectbots the Insectbot Hexa was born, with more legs, more sensors and new power source,

I will do a detailed tutorial with lots of pictures later but for now I do have that one and a video.

As the video embedding is not working, here comes the link: Insectbot Hexa

DreamMaker Overlord sneak preview

Well, it's time to inform you that the DreamMaker Overlord is launching on Kickstarter soon. 

UPDATE: Launch time is confirmed. It's 00:00h CST. For less confusion I did list some major cities here: 

 

ST Nucleo F411RE upgrade for Blizzard Bot

Aug 31, 2014

For ten dollars and change from Mouser, I can't resist. The 24MHz STM32Discovery board now in use is getting the boot to be replaced with a ST Nucleo F411RE.

An added bonus is the access to the mbed.org development environment.

Features

And it lives again!

The Robox, thanks to tech support, lives again.

I think I may have messed up the bed though, because there are some parts that seem to have bad adhesion for both ABS and PLA. I'm printing a case for my RasPi B+, but I'm leaving it to go because it's on layer 7 of 91 and it's after midnight. If the case prints nicely, I'll try to make some levels for mini-Groucho who is made of OpenBeams and I'm hoping to make the levels and attachments by printing them with Titon nylon.

Some of the levels are easy, but I'm hoping to build the motor mounts into the bottom level...

And now the Robox is dead...

After my first print, where the filament had already been in the printer for about 2+ days, I left it it there for another couple. By this time the filament was stuck firmly into the printer. I did get some back, but pulling a bit mor firmly than I should have resulting in the end of the filament coming off (nice clean break) but with some left in the printer.

So now I can't do any further experiments with the printer, and I am screwed until I can get that last bit out.

Any hints will be appreciated because I'm about to open it up by throwing it against the wall a few times. -

The Robox Liiiiiiives!

My 3d printer has printed its first "Hello World" glob of plastic. OK, it's a pyramid in draft format, and not particularly good at that. However, the PC finally recognized the printer and everything sort of worked.

I repeat, this was in Draft format. I will do more interesting things later

Pi Jumper

I finally had a chance to release Pi Jumper today!

Pi Jumper is my Raspberry Pi to breadboard breakout, designed to be useful in education (and at home).

Pi Jumper works well with Raspberry Pi models A, B and B+
