How about a Spider who obeys the order to sit, dances when he sees a light and dodges obstacles? All of this was assembled with just one board, the Arduino Nano 33 BLE Sense.

Spying Robot Vacuums Really Suck
LidarPhone exploits the LiDAR sensor in robotic vacuums to eavesdrop on your private conversations.
Just when you thought you had all your bases covered for privacy, it turns out that even your seemingly innocent robot vacuum may be spying on you. And all this time you thought it was only collecting dirt from the floor.
A team in Singapore took advantage of the LiDAR sensor typically found onboard robotic vacuums for navigation purposes, and repurposed it to capture sound with an exploit that they call LidarPhone. Laser microphones, in which laser beams reflected off of vibrating objects are converted into audio, are not a new idea. However, laser microphones require sophisticated setups and fine-tuning that is not possible with a stock vacuum cleaner. Getting a vacuum to work as a laser microphone took some clever thinking.
Arduino 3D Wire Bending Machine
In this tutorial I will show you how I built an Arduino based 3D wire bending machine. This is actually a typical mechatronic system because it involves mechanical, electrical and computer engineering. So therefore I believe many engineering students or anyone who is new into mechatronics found this project interesting.
Control a wheelchair using an EEG headset and Arduino
In an effort to help provide paralyzed patients with an easier way to operate their wheelchairs, these makers have developed a system that uses an OpenBCI brainwave cap to collect electroencephalogram (EEG) and electromyography (EMG) signals, literally from a user’s head. Data is then sent to a PC running OpenBCI software and passed along to an Arduino Uno via Bluetooth for control.
α-WaLTR Turns It Wheels Into Triple-Bladed “Legs” to Navigate Uneven Terrain — and Even Stairs
Built as part of a military program but with wide-ranging use-cases, α-WaLTR goes where other wheeled robots fear to roll.
Researchers at Texas A&M have designed a compact four-wheeled robot for whom stairs and other uneven terrain pose no problems — thanks to wheels which can transform themselves into “legs” on demand.
Dubbed α-WaLTR, for the Adaptable Wheel-and-Leg Transformable Robot, the robot has been built as part of DARPA’s Offensive Swarm-Enabled Tactics (OFFSET) programme under the leadership of grant awardee Associate Professor Kiju Lee. “Through this new project,” Lee explains, “I will develop unmanned ground vehicles with agile and versatile locomotive capabilities for urban military operations.
Make Eating Robot With Arduino Nano | Gold Screw
The idea for this project came from my daughter.
She wants a robot, and this robot can open its mouth so that it can put food in its mouth.
So, I searched indoors for things that were available: cardboard, Arduino Nano, ultrasonic sensor, servo motor… to be able to create a robot for girls to play in the fastest time, and at the lowest possible cost.
LEGO Steampunk Walking Ship (Strandbeest)
This is a custom walking machine built entirely out of LEGO components. It is styled as a steampunk/post apocalyptic trading ship and features several play features, including the functional cargo crane.
3D Printed Robotic Arm controlled by real-time simulation
Recently I’ve been working on this mini 3 Axis Robotic Arm which is controlled by my own real-time simulation.

A 3D-Printed SCARA Robot Arm That Won’t Break the Bank
In the world of industrial robots, six-axis models are perhaps what comes to mind. However, SCARA – Selective Compliance Assembly/Articulated Robot Arms – are also quite common, for applications where complicated 3D orientation isn’t needed. While these machines can cost many thousands of dollars, and are normally refined over years of work, YouTuber How To Mechatronics created a version of his own using four NEMA 17 motors and an array of 3D-printed components.
As seen in the video below, the device employs timing belts and pulleys inside the segments for power transmission and gear reduction in the horizontal direction. The Z-axis is driven by another stepper, along with a lead screw, held in place with a series of four rods and linear ball bearings. For the “hand” portion, a servo motor controls an end effector, enabling it to pick and place objects as necessary.
Tiny Machine Learning: The Next AI Revolution
Miniaturization of electronics started by NASA’s push became an entire consumer products industry. Now we’re carrying the complete works of Beethoven on a lapel pin listening to it in headphones. — Neil deGrasse Tyson, astrophysicist and science commentator
[…] the pervasiveness of ultra-low-power embedded devices, coupled with the introduction of embedded machine learning frameworks like TensorFlow Lite for Microcontrollers will enable the mass proliferation of AI-powered IoT devices. — Vijay Janapa Reddi, Associate Professor at Harvard University
