The Power Stage Variations The reason why PowerPACk32 was designed as two different boards was to make it easy to deal with the different topologies. Although a 2 board solution is often undesirable, when experimenting there are a few advantages worth...
Detailed technical description: (ax1 is the base rotation, ax2 the joint just above it, and so on...) For control I use 5X Teensy 3.2 microcontrollers, they are connected together into a single CAN network, (Odrive is also on...
The code for 3 Phase motor control is meant to run on the ATmega32U4 microcontroller, on our open-sourced 3 Phase Driver Board. We're currently testing on the following BLDC motors: Turnigy 480 850kv and Turnigy 480 1320kv, but plan to launch on the...

My goal is to make rc car autonomous racesVideos of the project development :Part 1 : Developping my own ESC. It's based on an Atmega328P (same as Arduino UNO) and has the following characteristics : - Works with BLDC motor with or without hall sensors-...
System Overview The Smart Knob is based on ESP WROOM 32E microprocessor module. The haptic feedback is realized by burying a BLDC motor in the main body of the knob. A magnetic sensor senses the direction of the knob and sends the angle to ESP32. ESP32...
One major reason for that is that there is a huge gap between the hardware that's used in commercial devices and in research prototypes. To make a successful robotic prosthesis you need a small, lightweight embedded system that can support high peak...
The focus of this project is a very low cost robotic platform that provides a test bed for a new model of machine cognition. A purpose built micro cluster serves as the 'brain' and the BigSack deep K/V store was optimized for cluster operation. The Robot...
This project starts where the Arcus-3D-M1 leaves off with a more narrowly defined set of build parameters.The current design is based on a Beaglebone Black/CRAMPS board running Machinekit, and some custom code. The interface is published as a network...
I was inspired by this mechanism : http://507movements.com/mm_131.html . I started by recreating the mechanism in SolidWorks with all the proper mechanical mates so I can see the mechanism for myself. It was really hard to relate the throw of the blade...
Edwards EXT255H turbo molecular pump controller BackgroundI have recently taken an interest in high-vacuum systems. A TMP is the bridge between the relatively soft-vacuums produced by traditional mechanical pumping systems and the high-vacuum world or...
This project has six systems that make up the cooling pack system. Power Management: Charger/Li-ion cell balancer.Dual battery pack management.(implemented in later models)Li-ion charger and DC/solar power input.TI MSP430 microcontroller power control...
Concept A gazebo simulation approximates the robot's physics and allows the user to control it with a joystick to have a feeling of the robot's power depending on the weight and motors power.nRF52840 Allows high throughput log with native usb uspport.A...
Open Hardware scanning laser rangefinder based on Time-of-Flight principle. There is a big article in Russian about this project: https://habr.com/ru/post/485574/ Google translation: https://translate.google.com/translate?hl=en&sl=auto&tl=en&u=https%3A%2F%2Fhabr.com%2Fru%2Fpost%2F485574%2FThe...
Overview My ultimate goal for this project is to develop an open framework for adding low cost power systems to unpowered mobility devices used by children. I like brining "structure" to a range of existing solutions, so my plan was to choose a...
