A spider quadrobot built with Prusa and Arduino Pro Mini

via Arduino Blog


It takes 14 steps, a Prusa i3 3D printer and a lot of soldering to build Spider Robot v3.0, a quad robot running on Arduino Pro Mini.  That’s what told us  RegisHsu, a maker who shared his project’s tutorial on Instructables and the 3d printable files on Thingiverse.

It took 12 months of work to build the robot and it reached the fourth generation of  design, that you can explore on his blog  if you are interested in its history:

This is my first project for the 4 legs robot and it took me about 1 year development.
It is a robot that relies on calculations to position servos and pre-programmed sequences of legs. I’m doing this is because of it could be fun and educational for 3D design/printing and robot control.

The robot allows cool customizations like adding IR detection:

Windows 10 IoT core controlling a Raspberry Pi 2 robot

Windows 10 IoT Core running a Raspberry Pi 2 robot by Scott Hanselman:

Starting with a Raspberry Pi 2, walk through the setup instructions here. You do need to have a Windows 10 today to installing Windows 10 IoT Core but at least it’s gotten a lot easier with the latest build for IOT. There’s an app that does all the work and you don’t need to go to the command line. Also get Visual Studio 2015 Community and the Windows IoT Core Project Templates. Basically just follow these step-by-step instructions.

Mearm forked

Bajdi’s self designed version of the mearm using 3 stepper motors:

Since I was not very happy with the original design I decided to make my own version. Goal was to make it much simpler to print, less pieces that don’t need to be so accurate to fit together. I used freecad to design my robot arm. Long time ago I used Solidworks at work and freecad is a bit similar in workflow. Did not take me long to design the arm. My mearm is a little bigger then the original version.
I recently found some cheap 28-byj-48 stepper motors that are rated at 12V (1.48$ @ Elecrow). So I decided to use those stepper motors instead of servos. I only use a servo for the gripper.

Matchbox car

via Dangerous Prototypes


Shane has been working on making small robots and made a prototype of a matchbox car,  a robot car that fits inside a matchbox:

This build consists of a tiny DC motors ripped from a pair of 9g servos, a h-bridge motor controller, an el-cheapo 8 bit pic and a 100mAh 3.7V LiPo battery.

The State of Free Hardware for Robotics

FreeIO.org is currently running a poll to determine what sort of free hardware project the community would most like to see developed. At present the poll is leaning heavily towards robots. So I thought it would be worthwhile to do a quick survey of existing free/open hardware robot projects to see what there is to work with and improve on. There are a lot of FLOSS (Free/Libre Open Source Software) robotics projects out there too but this article will focus on hardware projects that are under free hardware licenses. See the FreeIO.org “about page” to learn more about the concepts of free / open hardware.

I’ve attempted to list the projects roughly in chronological order by the project’s creation date. To qualify for this list, a project needs several attributes: 1) it must be a complete mobile robot, not just part of a robot such as a manipulator arm 2) the hardware design documents (e.g. CAD files, schematics, etc) must be available under a free license (i.e. a license that protects the user’s basic freedoms – licenses with commercial-use restrictions are NOT free/open licenses, 3) at least one working robot must have been developed and demonstrated. Projects that are in the planning stages didn’t make the list as we’d like to see well-proven designs that have been well-tested in the real world.

Read on for the full list of free/open hardware robot designs!
