BaseBot – Basic Robot Kit v1 Specs

Basebot is a simple Open Source Robot platform which intends to provide a good balance between price and performance. We want it to be as a base platform for boards like Raspi , Olinuxino , Carambola etc which can be mounted on top of it and they can control it serially. But it should be completely usable in standalone mode also.We did not provide any mounted sensors as we want users to use it as a flexible experimentation platform , while it takes care of simple robot like functions.

Magic blue smoke

As part of a mixed set of robot parts I bought on ebay I received this Dagu 4-Channel Motor Controller. On the back there was a trace broken so I soldered in a wire to replace it and hooked it up to the Rover5 (from the same set). Wired it to an Arduino UNO and programmed it to run a motor test. Applying power to the board, before the Arduino had even started PWM, one of the driver ICs began smoking.

Master Mk.1

This is the new blog for my MASTER robot. Given the suggestion about linking blog posts to robots, I thought I would start a build log and make a few notes about each part as I went along. I am already keeping the odd note about things so I dont forget them, but this way they are easily accessible and harder to lose (kind of like free cloud storage, but only for robot stuff)

 

Personal Update

I don't know how many LMRtians have been hit by the blizzard-I'm guessing a half dozen of us anyway.  We lost power for a while and still don't have interwebs at home.  I just made it back to work for the first time since my day at the hospital and this is the first chance I've had to check in.  Funny how LMR is my priority...

EXPECT US!

I'm not outing myself as a member of Anonymous or anything here (I would be flattering myself and lieing to say I had the skills to be a part of this), but more and more it becomes impossible to say I'm not on their side.

Robocop...ies

Sometimes, there are robots that are good as they are. It's not worth even to try to do my own spin of them. But because I like them so much I would like to have them/build them. So, I dedicate this blog post for reporting my assemblies of robot copies of other people famous robots in which I've just followed the instructions.

Arduino Wavefront Algorithm

First Up... If you want to find out what Wavefront Mapping is all about head over to the Society of Robots Tutorial. It has a great wtite up and its where I first learnt about it.

 

Basic's done, So lets talk about Map size limits.....

The Arduino 2560 & 1280 both have 8k of SRAM (where the map is stored)

I'm using an array of Int's, each Int is 2 Bytes, so max size would be the square root of 8k / 2.

8192 / 2 = 4096

Sqaure Root of 4096 = 64

This blog will contain everything that happens to me and my robotic life. 

NerdCam3D has arrived

Hi folks,

it really has been a while, my last post is months ago. But in the meantime I have made major progress. First of all I have bought an Axial Wraith, a RC-car that offers lots of hardpoints to mount and attach devices. Then some guy from the Geman FPV-community made a small GRP-case for the camera. In this way I was able to crawl through my backyard in FPV for the first time (see 1st attached video).

Happy St. Andrew's Day

I'm not what you'd call "religiously observant" but there aren't many holidays that apply specifically to robots or geeks (unless you count Bender's "Robonukkah," which some fans have placed in February and which I'll be sure to bring up around then, possibly with fembots wrestling in petroleum oil.)  So wired.com honored the long list of Scottish inventors in today's "This Day in Tech."

Of special note for hackers/open sourcers is this entry (directly quoted from article):

Why Do I LOVE New Projects?

 

Especially ones I've designed - especially when it seems like nobody else has done this before?

 

This should be as much fun as it will be frustrating . . . more soon . . . yeah c'mon!

 

Better Than Candy

Rocket Brand Studios/ CtC Update

Hey guys,

It has been a whirlwind around here for quite a while... Ever since Maker, it has been non-stop (and wonderfully exhausting).

I thought I would take a quick moment to record a video and let you guys in on the chaos and upcoming goodness.

Setting up my new lab

Hey everybody!

I have finally started setting up my new lab after moving to Canada! Wow! Went to few shops today, got myself some tools, parts, and stuff! The only problem is that my table was not delivered yet, so, here is a photo of my "Temporary refugie" robotics lab :)

Adventures In Robots: Robot #2 Bert the Bling Bot

Now that robot #1 is almost complete, (Ajax Harbinger of the Robot Apocalypse, robot entry coming soon), I have begun to plan out robot #2.

Robot #2 will be named "Bert the Bling Bot".  The goal of course is for Bert to be bigger and better than robot #1.  To that end Bert has the following requirements/goals.

Very Very Cheap Platform

So, I was starting on building my second robot, and I didn't really find enough materials around. I found straws and chopsticks, so I cut them up, glue them, and made them into a cheap base for my robot.

Adventures in Robotics, Numbers count

Today I was busy trying to interface an infrared detector to a PICAXE 28X1 on a project board.  My goal is to integrate this into my first robot, Ajax, so he can receive commands from an TV remote control.

The PICAXE documentation shows the 3 pins on the dectector wired to a a couple of resistors and a single capacitor, how hard could it be?

Two hours, later I am getting nothing on input pin0 at all.  Zero, Zilch, Nada.  Nothing.

The irin command never seems to return even though I give it a timeout value and a label to goto on an error.

$20 Robot platform

The Making of a Robot including Mcu for less than $20

This project was devised to show how easily it is to make a robot on limited funds.
It is a good "Starting Off" Robotic base as it can be easily changed and transformed.
This is just the start of the project and there are many additions planned for it.

Zifduino bootloader programming shield

When I first began working with Arduino I was amazed by the incredible things people were doing with the devices. After a couple of successes with my little UNO R3 I wanted to make some things using  "standalone"  chips. Following some tips from fellow Ardweenies I discovered this: http://arduino.cc/en/Tutorial/ArduinoToBreadboard

I also dabble around with quad copters

Here's one of my home brews . . . flies really well. My first quad using the Naza flight controller - very nice controller.

Sketchy businesses -- my 3D parts modelling log...

Well, currently there's not a day that goes by without me reading someone talking about 3D printing, 3D printers and whatnot. Also, I've been reading of how easy SketchUp is to work with, so given my failure to make anything of Blender around almost 10 years ago... I decided to give SketchUp a try.

Note: Newer designs are at the top (for chronological reading start at the bottom of the post)

 

02 - Second practical motivation:

Boards & Boards (to get you bored) -- a log of homebrewed circuits coming to life...

I decided to make a blog to serve as a log for the boards I design and/or produce... well mostly because I can. So here it goes.

NOTE: Older boards at the bottom, newer at the top. So do bottom-up read if you're after a chronological perspective.

Chickenparmi's Blog

Hello again everyone, my name is chickenparmi.

As suggested by ChuckCrunch I am making this blog post to give you a brief explanation of my past experience/knowledge in robotics and all the things I have made. I will post all my old stuff in this blog and stuff that I dont think to be worthy of a robot post as to avoid post spam.

Kimono - Saki avoidance

Kimono :- second addition to swarm farm ....(third and forth are already in the side lines .......)

As LMR is crawling/limping/lagging along due to server problems ..... project is posted Here .(with video)

 

Project Reprap Rostock Rosblog (Hopefully not ROSFLOP!)

Thought I would start a blog documenting my rostock build. Hopefully this will help some other noobs work out the minutae of a project involving so many disciplines!

Balanceiser - Yet another balancer robot

Ok here I will be tracking my attempt to make a balance robot .

Some photos from a raw sketch model I made in sketch up follows .

Ok here it is .

I will use a wii nunchuck as an accelometer and further input .

Driving a CNC machine directly from an STL file with a DAGU Spider controller

I want to drive a CNC milling machine using only an Arduino processor and an STL file. The STL format was chosen because it is very simple for me to understand and almost all 3D CAD software can export an STL file.

In my forum post here: http://letsmakerobots.com/node/34958 the feedback I go was basically.

Rostock Build Blog.

 

For years there have been many great versions of DIY desktop manufacturing tools, and one of the most fun to build (and watch while it prints) is the Rostock 3D printer, which uses delta kinematics to equate its motion.
