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

Boca Can Teach Anyone About Robotics

This simple, 3D-printed quadruped robot is designed to explore control theory and machine learning.

Anyone can learn about robotics, but what if there was an inexpensive, hands-on approach? That’s where Boca comes into play. Nguyễn Phương Duy designed his open source, 3D-printed platform for makers and researchers interested in exploring control theory, machine learning, and reinforcement learning.

Boca has eight degrees of freedom with some great moves to help you in your robotics research and study. It can be purchased in two different flavors if you so choose: either fully assembled or with a kit that has the required components to get started with robotics. Duy is also making a 12-degrees of freedom variant, set to be released soon.

Solar Tracking System Using Arduino and LDR | DIY | Automation | Robotics | Arduino | Technology |

Hello guys i have prepare this short DIY video on Solar Tracker which is very useful of solar panels / solar cooker and solar umbrella to adjust its self towards sun sunlight this system works with the help of 4 Light Dependent Resistor Each on four corners . So when ever the light gets blocked on corner the the servo rotates towards the light so the LDRs will be Parallel to source of Light You can follow this video and prepare this project for your schools Science projects and after a simple modification you can connect it to internet device and measure luminous intensity of light and monitor the battery charge and output voltage of your panel and you can use it as advance project.

DIY – How to make 1:150 micro RC Car

I modified the TOMYTEC “THE Car Collection” 1/150 TOYOTA CROWN to work with a remote control. The car is controlled by a self-made infrared remote control.
The remote control format is proprietary.
The battery installed in the car is a lithium polymer battery(3.7V 40mAh).
I used motors by removing weights of the vibration motors.
In order to write the program of the microcontroller(ATtiny1616) used on the car, you need ATMEL STUDIO 7 or later and a device that can use UPDI.
I use MPLAB PICkit 4. AVRISP mkII cannot be used.

An EXTREMELY TINY Car Tutorial You Can Drive! – (87 times smaller than real life)

Have you ever wondered what it takes to build an extremely tiny car that you can drive on your desk… and have so much fun doing it! This tutorial is for you!
I’ve been building models and realistic scenery for a while and I’ve always wanted to shrink down and walk around my creations… but since that is not an option just yet the next best thing is to be able to do it in a third person view by driving a tiny HO scale car through my scenes, and with this tutorial you too will be able to go on a tiny road trip 😃
