ROBOTS EVERYWHERE
In response to the COVID-19 pandemic and the global shortage of personal protective equipment (PPE), we collaborated with Open Source Medical Supplies to develop a number of emergency methods and techniques. One of them is a way to prolong the usable life of N95 masks in shortage situations. This system was designed to be simple, cost-effective, and adaptable to available resources, making it accessible to those in critical need.
We use artificial intelligence (AI) at Robots Everywhere, and with the uncertainties around the safety and ethics of AI programs, we wanted to share some clarity with everyone.
Matteo has become a bit of a legend around the Robots Everywhere shop as “the strain gauge whisperer” for their ability to use Propeller microcontrollers and analog circuits to get very accurate readings out of strain gauges. Once again, a client has come to us, this time BudBot.
Electric bicycles, or e-bikes, have become one of the fastest growing markets in human transportation. Combining many of the advantages of both a bicycle and a motorcycle, while being power efficient enough to charge with solar panels, no wonder over a million e-bikes were sold in the US in 2023. However, unlike purely mechanical bicycles, e-bikes produce e-waste. We propose a solution.
This article will guide you through a simple yet effective way to modify a laser GRBL board to drive a spindle motor. By utilizing an IRLZ44 MOSFET and an NTE598 diode, you can control a spindle up to approximately 36 volts and 12 amps. This is an easy project to enhance your CNC.
We'd like to showcase the bespoke work we've been doing using the Parallax Propeller. The Prop and Prop2 are unique multicore microcontrollers made by Parallax Inc; their architecture allows for executing parallel tasks in hardware, which makes them perfect for things like autopilots or applications that need to control a number of motors and sensors at once. The Prop is a capable brain for small and medium robot designs, and an excellent spine for more complex designs where a Pi or other SBC has to do the abstract thinking.
The SMOL is Robots Everywhere's latest robotics platform, and it has a rather long story behind it. To introduce the SMOL, it is a tiny mobile camera system that can connect to, or provide, a WiFi network that allows a user to control the robot via a web interface or API. It is designed for extensibility - more servos, more sensors, different chassis - and we hope retail customers will enjoy it as much as our industrial ones.
We love posting cool L-Cheapo projects sent to us by our customers, and this one comes from Duarte Silva of Portugal. He's done a few engravings like this on his new L-Cheapo Mk7, and I do say they've turned out very well. Check out the video, too!
One of the things we decided we wanted to do before the launch of Antbot 2.0 is replace the store. The old web store was built on a dated engine that lacked a lot of convenience features for users, and was specialized for the use case of one user purchasing one product. This worked well for the early days of L-Cheapo, with no options, giving users a 'push button, receive laser' experience. As our range of products evolves, so too must our store.
As part of the Antbot 2.0 development, we've invented a new form of rocker-bogie suspension (patent pending), that uses a cable system to balance the rocker arms. On October 16th, we presented this design at the Mars Society Convention. Now that they have posted our presentation to the general public, we would like to share this mechanism with you!
