Let's Make Robots!

Five Volt ARM chips

Today at work Atmel came to visit my company with their Tech on Tour truck.  I spent most of the day getting demos and classes from them.  There were quite a few interesting tidbits that might be of interest to LMR members, but one stood out.  That was their new line of Five Volt ARM Cortex M0+ processors, the SAM C series.  Why is this important to LMR members?

I have to give credit to this artist/site

Hello Let’s Make Robots!

You have likely seen that RobotShop has acquired Let’s Make Robots and are wondering what this means to LMR and everything that has been implemented so far.

RobotShop Acquires LetsMakeRobots.com

RobotShop, the leading source for robots and robot parts on the web already hosts one of the largest communities of robot and drone enthusiasts. In 2010, in order to better serve their community by providing free information and articles accessible to all, RobotShop acquired GoRobotics.net, one of the most popular and oldest blogs on robots.

A brief note from my little sister

Here's a quick speech from my little sister. She's been helping me with the testing my robot is running through, and has had fun interacting with it when it tracks her face and talks to her. Here she is with a call to get girls into tech:

Remote Weather Station

This is a work in progress weather station with wireless transmitting, it is made using cheap components, so here is a list of components all purchased off of ebay ecept for my trusty genuine arduino dumelnove, which will be replaced with a $4 uno clone off ebay in the final project. Still need to build enclosures for both the indoor and outdoor units. It is based on this instructable.



New Chassis - not the same

I thought I had found the perfect 4WD chassis for Minion 1.  It looks almost identical to the 2WD chassis I am currently using.  Then, I take a closer look at the New Bright Rhino, and see that it is skid steer.  Hmmmmm...

Creating Simple Android Apps with MIT App Inventor 2

I plan to edit this blog. Think of this as a public "draft" version. I thought even in draft form some of this infomation could be useful to LMRians.

MIT's App Inventor 2 is a web based application for designing Adroid Apps.

I both love App Inventor 2 and hate it. I love how easy it is to use. If you want to make an app with a few buttons to send data over Bluetooth then AI2 is the perfect tool to develop the app.

Lobsang- my progress so far.

Here's a quick explanation of what my robot can do:













First blog entry for PiWars!

Hello all! This is my first entry for the PiWars 2015 blogging challenge. I have my robot post here but it's just a post, so now I'm going to blog about Lobsang, my robot, in the designated area of LMR. Hopefully there will be one or two posts per week.

Have fun reading!

Autonomous navigation Robot

I'm trying to make a robot able to navigate autonomous though GPS waypoints. 

So far I've read and seen tutorials for individual hardware and trying to understand how it all works.

Next step will be to try and program something that will work.

Hardware I've
An adafruit ultimate gps.
micro sd card and breakout board for micro sd card
A HMC5883L compass sensor breakout board
Arduino Mega

Modular esp8266 local network


  • user needs to configure only the first module
  • as easy as possible to add new module
  • each module has a purpose
  • modules know what modules are online
  • accessible singularly
  • wireless configuration

Spherical Pendulum Robot Ball From Scratch


This will be a page where I'll share progress on developing a pendulum robot ball. At the moment I don't now much more than an hour of research. 

My plan is to 
Do a CAD drawing in Inventor 
3D print a prototype.

LED board (LDR operated)

hello everyone, i have made another board today. looks ugly, but works.

Solar powered motors

Test with solar panels and motors!
3 solar panels give enough current to move a couple of these popular 3-6v motors, with 6 470uF capacitors as buffer.

I will test soon with an arduino nano and a driver:)

UV exposing box timer. (used atmega48)






Parametric Printable Meccano

Here a link to a parametric meccano model.

If you know really little about OpenSCAD you can easily configure this file to make meccano-like pieces.
I modeled it because i need often to whip up a mechanical prototype, for hackatons, demo or just playing around :)
At the moment there are the plain piece, the 90° and 45° bent pieces and the C shaped piece, like in the image.

Making robots

Just joined the site after reading the entry on six-wheel robot suspension by Oddbot and seeing Titan in action.

My next mini project - Self balancing bot

Almost done with my boom/gripper build and wanted to make another quick bot (well quick to build) Going to do a self balancer. Need to find an IMU or accelerometer, I have some somewhere in a box....  Only found a compass and just mounted it to look for a good place. May place it lower and the battery higher.  Going to make a tuning python GUI to set the balance variables via bluetooth.
