Mechpen drawbot
Alexander Weber has a nice build log on his drawbot called Mechpen, that is available on GitHub: This is Mechpen, my newest drawbot. The idea was to have a robot arm that could sketch on a rather large surface. It is a SCARA (Selective Compliance Assembly Robot Arm) robot arm, meaning the robot has a […]
RobotX is open source
James Bruton writes, “I’ve decided to open-source RobotX so anyone can have a go. I also made some extra foot sensors for the robot in the video below. You can get the CAD and code from my Github.” See the full post on XRobots blog. Check out the video after break.
Curiosity Mars Rover
The Curiosity Mars Rover project from Beatty Robotics: We are excited to share our latest and most ambitious robot, the Curiosity Mars Rover. This is a highly-interactive, 1/10th scale functional replica of the NASA Curiosity Mars Rover. This project was ambitious for us in two main ways: First, we worked very hard to make the […]
DIY robot design
A computational abstractions for interactive design of robotic devices by Ruta Desai, Ye Yuan and Stelian Coros from Carnegie Mellon University’s Robotics Institute: We present a computational design system that allows novices and experts alike to easily create custom robotic devices. The core of our work consists of a design abstraction that models the way […]
MeArm Pi – Build your own Raspberry Pi powered robot arm!
Here’s an interesting open source project on Kickstarter the world’s first robot arm kit for the Raspberry Pi, the MeArm Pi: We believe in helping people understand how the world works. With so much development going on in robotics at the moment, now is the perfect time to get to know what it takes to build […]
R2-D2 build
Bithead942 blogged about his R2-D2 build: To really bring R2-D2 to life, I knew I had to do some great sturff with electronics. I started with a Taranis X9D controller and a pair of X8R receivers configured for a full 16-channels. I chose this platform mainly for its versatility, but also because I wanted to […]
Tote – Quadruped robot
Radomir Dopieralski has a nice build log on his quadruped robot – Tote: Tote is a small (fits inside your palm), four-legged, walking robot, with three degrees of freedom per leg, Arduino for its brains and controlled either with a TV remote, or by additional electronics added on top of it. It is very simple, cheap […]
Jumping robot leg
Ben Katz documented his robotic leg project: Here are the python scripts that send serial commands to the motor controllers. Here are the eagle files, gerbers, and BOM for the motor controllers and sensor boards. When I sent the boards to 3PCB, the text the motor controllers got all scrambled so keep that in mind. […]
Dobot: Robotic Arm for everyone, Arduino & Open Source
Here’s an interesting open source project on Kickstarter the magical robotic arm, Dobot: Designed for DESKTOP. Arduino-powered, 4-axis parallel-mechanism robot arm with High Quality. For makers, educators, and everyone! We are six engineers who built a 4-axis high accuracy, high repeat precision, stepper motor, Arduino-based, desktop robotic arm called Dobot. You can visit his Kickstart page […]
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 […]
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 […]
Matchbox car
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. Project […]
InLinea01: A PID controlled line following robot build on an ATmega 8
Davide Gironi made a PID controlled line following robot: InLinea01 is a simple PID controlled line following robot. This is not speed oriented line follower, this is just a prototype I built to experiment with this type or machines, though it can be the first step to build a faster one. The goal of a line […]
Miniature machine controlled by heat and electromagnetic fields: TermiNature
A Miniature Origami Robot by MIT and TU Munich researchers: The unfolded robot, which is made of a magnet and PVC sandwiched between laser-cut structural layers (polystyrene or paper), weighs just 0.31 g and measures 1.7 cm on a side. Once placed on a heating element, the PVC contracts, and where the structural layers have […]
ESP8266 running NodeMCU as a controller
jscottb over at LetsMakeRobots writes: My goal for this mini project is to create A simple autonomous rover with just the ESP and NodeMCU. In looking at the specs for node most of the supporting libraries already written. GPIO, PWM and Timer libraries are included in the Lua interpreter. After flashing the board my next up […]

Modifying a Tower SG90 servo for continuous rotation with potentiometer position sensing, Part 1: Investigation and continuous rotation
Keith wrote an article on modifying a Tower SG90 servo for continuous rotation with potentiometer position sensing: On its own, the servo takes power, ground, and a position input and moves the shaft within a range of rotation to match the angle requested on its input wire. It has one or more stops in its gearbox to […]
