🤖 Robot axes, drive safety, and power architectures

Depending on the intended tasks, robots can have varying axes and various axis configurations - robot kinesiology

A robot axis of motion is often called a degree of freedom (DoF). Robots with higher DoFs have access to a greater amount of space and can perform more complex tasks.

1-axis robot is capable of linear motion in a single dimension.

2-axis: is usually composed of two linear guides that enable two-dimensional motion, such as an x, y, or y, z configuration.

3-axis: is a basic 2-axis design with an additional linear axis guide, or a cylindrical guide, that enables x, y, z motion.

4-axis: adds the ability to rotate the object that it is holding.

5-axis: adds the ability for two-dimensional rotation of the object it is holding.

6-axis: can mimic the motions of a human arm with three linear DoF and three rotational DoF.

7-axis: design placed on a rail or stage that enables it it to move from point A to B.

🎬 Introducing Stretch

Meet Stretch, a prototype of our new robot designed to automate box moving tasks in warehouses and distribution centers. Stretch’s mobile base allows it to go to where repetitive box lifting is required - unloading trucks, building pallets of boxes and order building. Stretch makes warehouse operations more efficient and safer for workers.

🤖 3D Printed Robot Arm

This robot arm is made almost entirely of 3D printed parts that snap together. It has three servo-controlled joints, plus a rotating base and gripper.

The arm is controlled by a series of buttons that connect to an Arduino Uno hidden in the base. A simple circuit makes connecting the servos and buttons to the Arduino easy and makes set-up and assembly very quick.

📰 How NASA's Oxygen-Making Machine Could Change Mars Forever

Whether for breathing or sending rockets back home, we'll need to make oxygen on Mars. Soon, we'll know if it's possible.

According to NASA’s estimates, a four-person crew will need a lot of propellant—approximately 15,000 pounds of fuel and roughly 55,000 pounds of oxygen—to generate the thrust needed to leave the Martian surface and return home. Lugging all of that oxygen from Earth is a hassle.

That’s where the Mars Oxygen In-Situ Resource Utilization Experiment, or MOXIE, comes in.

Roughly the size of a car battery, MOXIE is one of NASA's many in-situ resource utilization (ISRU) experiments and the first to travel to space. In essence, ISRU is the agency’s version of homesteading, and the experiments explore ways for future spacefarers to produce things from resources available on other worlds.

📷 Discord Security Camera With an ESP32

Use an ESP32 Cam and a passive infrared (PIR) sensor to create a motion-activated security camera that will post a photo to a Discord channel, where you have access to create a webhook.

We'll build out the test circuit, using a breadboard and jump wire. We'll then build a wiring harness using Dupont connectors to allow for easy connections to the development board and PIR sensor.

We'll then use our choice of a wall or ceiling-mounted 3D printed case to contain our parts and our camera.

The ceiling-mounted camera makes use of an inexpensive decoy camera that can be purchased online.

📲 Over-the-Air Updates with AWS and FreeRTOS

What you should know about over-the-air communications using AWS and FreeRTOS

Updating firmware in the field has always been a critical component of even the earliest of embedded systems.

Access to hardware interfacing tools like a JTAG or SWD programmer provides physical access to embedded system programming ports. Other access methods for firmware updates include interfaces such as USB, automotive CAN, a serial port, and so on. Wireless port connectivity has gained prominence as more embedded devices become part of the IoT.

In today’s post, we will explore such wireless, over-the-air (OTA) communications using Amazon Web Services (AWS) and FreeRTOS.

🔧 PCB routing in Python

Preferring to spend hours typing code instead of graphically pushing traces around in a PCB layout tool, [James Bowman] over at ExCamera Labs has developed CuFlow, a method for routing PCBs in Python.

Whether or not you’re on-board with the concept, you have to admit the results look pretty good.

📟 Monitor and Control Weather Station with Telegram Bot

ESP32 based weather Station whose Sensor Readings can be fetched and Outputs can be controlled from anywhere using Telegram Application

We'll add a feature to this weather station which makes it to be accessed and controlled from anywhere in the world.

We'll create Telegram Bot for our Weather Station and program it to get interact and give responses about sensor readings and relay outputs whenever we will contact it using telegram Application from our Smartphone or from PC.

📰 The Scientific Instruments of the Mars Perseverance Rover

Perseverance is equipped with seven scientific instruments that are specially engineered state-of-the-art sensor modules designed for use on Mars with the goal of testing, sampling and analyzing the geology and atmosphere of the planet and any potential biological signatures.

▫️ Mastcam-Z - is a mast-mounted camera system tasked with the job of taking panoramic and stereoscopic photographs of the surface of Mars.

▫️ MEDA is a meteorological system created to take measurements of the Martian weather, atmospheric pressure, temperature and humidity but also the wind speed and direction.

▫️ PIXL is the rover’s Planetary Instrument for X-ray Lithochemistry. It’s a module that houses an x-ray spectrometer that can identify chemical elements at a very small scale.

▫️ RIMFAX - the Radar Imager for Mars’ Subsurface Experiment - is the first radar wave tool sent to the surface of Mars on a NASA mission.

💻 Crystal Language That Aims at C Performance with Ruby Syntax Releases 1.0

Crystal, a new object-oriented, compiled systems programming language that aims to blend the conciseness and friendliness of Ruby with the efficiency of C, recently released its first major version.

Crystal 1.0 has a syntax close to Ruby’s and features statically inferred types, C bindings, and macros. Crystal may attract developers with a Ruby/Rails, Elixir/Phoenix background.

The Crystal team explained the rationale behind the new language as follows:
▫️ We love Ruby’s efficiency for writing code.
▫️ We love C’s efficiency for running code.
▫️ We want the best of both worlds.
▫️ We want the compiler to understand what we mean without having to specify types everywhere.
▫️ We want full OOP.
▫️ Oh, and we don’t want to write C code to make the code run faster.
