First test run of Hovermower on a sunny day. Works good so far but still lot of work. First I need to get rid of poor wifi signal in garden. I have one router and two repeater acting in a mesh in my house. But this seems not to be working well outside. Maybe I need some kind of wifi bridge to...

To be honest, I don't have concrete plan here and I'll see, how well it will work with camera only. However, for the beginning and safety purpuses, I'll use existing perimeter wire of Ardumower. I did some tests and it works reliable to stop the robot if both perimeter coils are out. This should...

Next Milestone reached. I had some hard times to get ROSMower up and running. It was easy to set up ROS to teleoperate the robot around. It was also easy to get Lidar and IMU working as well as my base controller, which acts for power management, perimeter and bumper. But the Intel RealSense...

Falls noch jemand einen DIY BLDC Treiber sucht, ich habe einen übrig

Milestone reached. HoverMower (name of 3D printed chassis) is complete now. Everything fits perfectly and is operational. You can equip it with any electronics you want, a PCB1.3 should also fit inside the PCB Box (red). As already explained, you can use a simple UART interface to control each...

Hello, thank you I didn't know this before. So it acts as it should. Because I tooked everything from Azurit Code, I wonder what I've missed here. At Azurit, you also define which perimeter signal you want to use. But they're defined the same way as in sender so therw must be some Code which...

Hallo, für meinen Mower basierend auf ROS habe ich mich am Perimeter Code von Azurit bedient. Als Sender kommt der normale Sender Code zum Einsatz. Als Empfänger dient ein Arduino Nano, der mit zwei Spulen ausgestattet ist. Dabei verwende ich die Perimeter Klasse von Azurit und den ADCManager...

Some remarks, Arduino use 10 Bit for ADC sampling

Hello Bernard, It is necessary as analogRead is blocking function so the Arduino won't be able to act as Perimeter receiver. ADCMan is interrupt driven. Battery Management with Jetson Nano or RaspberryPi is odd as it needs some time to boot and set pin to high. Also it will not monitor battery...

Ich habe den Fehler gefunden. Ausgangsbasis meiner Software war der Sketch PerimeterV2 aus dem Tests Ordner. Die hier verfügbare ADCMan Klasse unterscheidet sich deutlich von der aus Azurit. Die Testklasse liest nur 8 Bit und der gelesene Wert wird zusätzlich auf max 127 begrenzt.

Hallo zusammen, für meinen neuen Mäher (Hoverboard + ROS) benötige ich eine Art Base controller, welcher das Batteriemanagement, Perimeter und den Mähmotor übernimmt. Dazu habe ich die bisherige Schaltung für Batterie und Ladungsmanagement auf einer eigenen, kleinen Platine untergebracht...

Hoverboard Motoren sind ja nichts anderes als brushless Motoren und somit sind diese entsprechend leise. Drehmoment haben die ohne Ende, die sind schließlich dafür konzipiert, 150kg Mensch mit bis zu 20 km/h zu fahren. Für einen Rasenmäher sind die eigentlich überdimensioniert und viel zu...

Tatsächlich ist mein Rasen ziemlich eben. Die meisten kommerziellen Mäher sind mit Heckantrieb und ja, alle scheitern an Steigungen. Für wirklich steile lagen eignet sich meiner Meinung nach nur ein Allradantrieb, der wieder eigene Probleme mit sich bringt. Es bleibt wie bisher, der Aufwand...

After vacation and some work the last couple of days, I made a huge progress in building hovermower.I've updated all repositories of chassis and want to share the current state with you.

Hello, the last couple of days (or was it weeks?), I planned a new 3D printable chassis which fits to Hoverboard Motors. Some of the initial ideas you find in this thread. This is my 4th Mower project and in past, it was always a nightmare to build a proper documentation afterwards. So this...

My current Arctic Hare chassis uses a moving top cover, so entire chassis acts as bumper. I tried to achieve this again. So here is a new version which is, heavily inspired by the work of Robin Fröjd. It has again an fixed motor section with an PCB mount. These parts are static. The front covers...

I use the origin PCB of Hoverboard as motor driver. There is a firmware available https://github.com/alex-makarov/hoverboard-driver It uses UART to communicate, so you simply need to send a command in a given protocol and it will drive. So I don't use Ardumower PCB for this robot but it...

As I'm currently waiting for some components, I started to build a 3D printable chassis from scratch. I call it HowerMower, as it is based on Hoverboard Motors, battery, PCB as motor driver and some other components of Hoverboard. All motors operates at 42V, just because Hoverboards do so. But...

Hello, if someone needs a new motor driver PCB, I'm currently selling one driver V1.0. This is the DIY Version and it has never been flashed. If someone needs a replacement, it might be helpful as shop is currently out of stock. I sell it as my new mower will work completely different...

After some development time, I finally got a LD06 360deg TOF Lidar and BNO085 IMU up and running. This video is a first outdoor test on a sunny day. Lidar works good so far even outdoor. The small dots displayed on the right side or area aren't noise, these are poles of my childrens playground...
