Meet Dot – A stamp sized 2-wheel robot powered by a Raspberry Pi RP2040 board

Kaisar (aka Roboticbits) has developed a tiny robot based on Pironomi Tiny 2040 Raspberry Pi RP2040 development board, which he/she claims is the smallest in the world, but it might not be depending on how one measures it. Nevertheless, the Dot is a cool project with two wheels with a 3V DC motor attached to the 22.9 x 18.2 mm board, and a 70mA battery to power the mini robot. Here’s what it looks like in action. Introducing Dot.. a stamp size @Raspberry_Pi #RP2040 robot.. the smallest in the world! Makes a proper use of the @pimoroni #Tiny2040!#raspberrypi #robot #robotics #make — kaisar (@roboticbits) November 11, 2021 Eventually, the robot should be documented on Github, but at this time we have limited information with a photo accompanying the video demo above. Tom’s Hardware got more details about the software as well, with Kaisar saying the firmware was developed with […]

Viomi V3 Max – A 3-in-1 sweep, mop and vacuum cleaner robot (Sponsored)

Viomi V3 Max Robot Vacuum

The Viomi V3 Max Robot Vacuum offers more than your typical Lidar robot vacuum cleaner as it features three functions, namely sweep, mop, and vacuum cleaner. It can even combine sweep & mop modes to thoroughly remove dust, dirt, water stains, crumbs, pet hair, and footprints on diversified floors. The Viomi V3 Max is born for mopping with an exclusive deep cleaning algorithm running on the Cortex-A35 processor powering the appliances, mimicking the manual way of mopping with 97.5% of cleaning coverage in order to ensure stubborn stains are removed without damaging the floor. An Auto Boost Mode enables perfect carpet cleaning with suction power automatically boosted to 2700Pa. The vacuum cleaner can either be fitted with 2-in-1 dust and water tank (400ml dust bin + 200ml water tank) to enable sweeping and mopping at the same time or an optional super-sized 700ml water tank that is large enough to […]

ANYbotics’ ANYmal C robot is a multi-module machine (Sponsored)

anymal c legged robot ml industrial inspection action

Rugged four-legged robot with three brains ANYbotics provides solutions for robot applications with the most advanced mobility and autonomy requirements in challenging terrains. The massive embedded computing performance for the key tasks – situational awareness, motion control and mission fulfillment – is delivered by three COM Express Computer-on-Modules from congatec. Due to the advancements in computer-based intelligence and sensor technology, previously stationary robots unaware of their environment are now evolving into smart autonomous mobile robots. This will not only help to relieve humans of potentially dangerous tasks but also to optimize repetitive tasks in real-life environments from an economic point of view. Such robots can autonomously fulfill many jobs that previously required human labor and significantly extend the list of feasible tasks. With such a perspective, it is not surprising that robot applications are a booming market. The overall global smart robot market is expected to grow with a CAGR […]

Valetudo is a cloud-free web interface for robot vacuum cleaners

Valutedo cloud-free vacuum cleaner web interface

In my review of Kyvol Cybovac S31 LDS smart robot vacuum cleaner, I noted that app permissions meant both the map of your house and GPS coordinates may be sent to the cloud. But it was pointed out to me that earlier LDS robot vacuum cleaners from Roborock/Xiaomi were supported by Valetudo project that removes the need to connect to the cloud, and implements a mobile-friendly web interface as well as MQTT support for integration with Home Assistant or Node-RED. The project is not a custom firmware for the robots, and instead, the stock firmware is patched with Valetudo which developers describe as an “alternative App implementation + mock cloud which runs on the robot itself.” The good news is that you don’t necessarily need to teardown your vacuum cleaner to root it and install Valetudo, but it will depend on the model, and manufacturing date/firmware installed. The less good […]

Ring:bit Car is a $20 Robot Kit for BBC Micro:bit

Elecfreaks has launched a robot kit designed for BBC Micro:bit that comprised of a chassis, and Ring:bit board with 3 channels of GPIO, among which 2 channels are used for driving servos.

Open Surgery Initiative Aims to Build DIY Surgical Robots

Medical equipments can be really expensive because of the R&D involved and resulting patents, low manufacturing volume, government regulations, and so on. Developed countries can normally afford those higher costs, but for many it may just be prohibitively expensive. The Open Surgery initiative aims to mitigate the costs by “investigating whether building DIY surgical robots, outside the scope of healthcare regulations, could plausibly provide an accessible alternative to the costly professional healthcare services worldwide”. The project is composed of member from the medical, software, hardware, and 3D printing communities, is not intended for (commercial) application, and currently serves only academic purposes. Commercial surgical robots can cost up to $2,000,000, but brings benefits like smaller incisions, reduced risks of complications and readmissions, and shorter hospital stays thanks to a faster recovery process. There have already been several attempts within the robotics community to come up with cheaper and more portable surgical […]
