Large Scale Humanoid Concept

Did some CAD using SolidWorks, and made this:

 

Free BT Android Control App

I guess some folks have been looking for my old robot app. I decided to post it here for any/all to use for free. I have long since lost the instruction manual I wrote for it but it should be pretty easy to set up and use.

If anyone wants to write a quick info manual, please do.

Basically,

Jetduino: Robotics interface for NVIDIA Jetson TK1

I have been working on a new interface board for the Jetson TK1 embedded supercomputer called the Jetduino. It makes it very easy to build robots that can use the parallel processing capabilites of the NVIDIA GPU for vision and neural neural networks.


second aduino arm

This is the

second arm i built

bigger base servo

better claw

more repeatable and less wobble

video of it working

picks up object

drops it at top of slide

repicks object

This is my first attempt at an arm

My first attempt at an arduino uno arm

4x micro servers

lollypop sticks

bent paperclips

and a whole load of hot glue

etc etc

powered by farnell 5v supply as very jittery on batteries

you tube video of it working (sort of)

CURT THE CREEPER

Hi,

I am a new member to Letsmakerobots and so far I am very impressed with the site, the people, and the projects.  I hope to learn and share with you all in the facinating and rapidly developing field of robotics and AI.

How to choose battery for Racing Drone

How to choose battery for Racing Drone Larger battery provides longer flight time. on the other hand It increases weight and thous decrease speed As the battery gets heavier, the increase in flight time becomes smaller. Eventually it will reaches a point where it just doesn’t gain any more flight time with bigger battery (even lose flight time). LiPo batteries (short for Lithium Polymer) are a type of rechargeable battery that is the battery of choice in the RC world . Chacteristic of Lipo Betteries RC LiPo batteries are light and can be made in any shape.

voice recognition and access port won't work small prob help please ;(

i have used this before on a diffrent computer but  im trying to use access port to code the voice reg module on a old windows computer not to oldlike 2005ish ;(  when i hit start monitor it says error pecifify file or port make sure your an addminastrator, and access ports not already running in the backround. and when i hit settings and ok it said error port not on or never been used before and send to pecific port

New LMR Logo Kit

Here is the LMR logo with the new slogan, as voted upon by the LMR community:

The LMR logo concept was originally designed by Nicolas Dupont (ndupont).

The Logobot is made by Jon / Psycop / Psy (psy).

where to get spear parts for junk parts robots

it would be cool to be able to just take apart a calculater, an old printer or tv and have enough knoledge to turn its parts into a funtional robot. But maybe you can!! And im  about to show you how, all you need are:

some intermediate electrical engeneering knoledge, curcuits etc. 

* a multimeter (an advanced electricity meter for curcuits)

* old tv,printer,electrical toy like spy gear etc.

Conquer the Divide - Faster Integer Division

Conquer the Divide - Faster Integer Division

Introduction

How to implement C-style integer division on a microcontroller that doesn't provide appropriate instructions? In school we learn how to divide long nunmbers [1]. Wikipedia tells us that we can do better in certain cases [2]. However, these algorithm are only better for numbers longer than a certain limit. For C operations they don't give any advantage. This article presents an algorithm based on piecewise polynomial approximation to implement this operation.

Control DC motors with a Grove H-Bridge and DynamixShield

I just uploaded a new video tutorial on how to use the Grove dual H-Bridge module with the DynamixShield and an Arduino Due to control DC motors. 

Grove H-Bridge with DynamixShield

[PIWARS] Overview

Well, here we are, very close to the competition itself! What I want to know is where did all those months go?? It seems like only yesterday that I got that email saying I had been selected to compete! But on the other hand after all this hard work over such a long period Lobsang is getting quite sophisticated, though I don't know if it is enough to win any prizes at Pi Wars.

[PIWARS] GitHub repository set up, OLED scares, new mounts, line follower update

I've finally created a GitHub repository for my code that runs on Lobsang (it was pretty hard to get the local repository program working, but I managed in the end!). It is somewhat patchily commented, so I can't guarantee that it's all completely understandable, but it's there if anyone wants to take a look. The file which may be of interest for people to use themselves is Oled.py- it's customized to my robot, but can still be used without the hardware I have. It's for Pi to SH1106 OLED communication.

ComMotion Motor Controller Shield

Need help with the ComMotion Motor Controller Shield. Searching at this site for info on this shield leads to many pages with 404 errors.

Examples of broken links related to ComMotion are:

[PIWARS] Progress update- manual control, speed test

Another update on Lobsang! I've been doing lots of work on the code so a lot of the progress is not visible. However, the Lobsang.py library and the RasPiO Duino's core.ino have bee heavily modified. New functionalities have been written and the whole boot-up process is a lot smoother.

Let me expand on the boot process as to hackers and roboteers (ie. not normal people!) it is quite interesting.

1: Power switch set to 'ON'. Pi, Duino, and everything else on Lobsang is powered on.

Share About Yourself With the Biography Option in LMR

 

We have recently added a Biography option to LMR so members can share about themselves and their experiences with robots to other LMR members.

Here's how it works:

Click on the My account link on the top right on any LMR page.

Under the info tab, you will find a new section called Biography and a link under it called Edit your biography.

Trouble Embedding Videos

Hello everyone,

Unboxing from the box...

I have found great deals at "...inthebox.com" and they are great at creating rings and loops to jump through if, somehow you are charged ALOT for a misconception...or not. After months, (MONTHS) of trying to get their attention, being told to go to this, select that, press this, click that- I still have not received refunds. Anyhow- will update this rant. Regarding unboxing; the LCD modules (4 of them) all were faulty. These will the nice white on blue that mount over the mega, no wiring.
