The robot is made of aluminium and uses harmonic drives for all axes so its pretty solid. Originally the motors are brushed dc (which are simple to control), sadly axis 2 and 3 lack power and need to have more oomph. Id like to use cheap, lightweight...
The quadcopter was made from a simple aluminum frame and was driven by four 1Kv BLDC motors. The control was achieved by using KK flight board and RC based. The the fuselage of the aircraft was built from old polycarbonate sheet and the wings were...
The Tiny BLDC board measures 1.3" x 0.9" (33 mm x 23 mm). The reason why we can make a BLDC motor driver so small is because PAC5223 has pretty much all the circuitry required to drive the power FETs. These components are:3 phase pre drive power stage3...
In this project, we are trying to drive a BLDC motor in very low speed. This means we need to have a very low PWM values update rate. However, the PWM values update rate is constant, the rotating speed of motor's rotor may not being what you expected....
Here are some general goals:By modular i mean, it consists of 1 ... 3 Parts. Mainmodule with µC (Mostlikely ATMEGA, and Arduino compatible) and Motor PreDriver (DRV8301DCAR)Module for Buscommunication (Interfaces UART, I2C and SPI (so you could...
The onboard microcontroller ATtiny261A generates 3 Phase (3 channels PWM for U V and W phase) 32KHz PWM from Timer 1. This result in resultant vector A.K.A position of the rotor of the BLDC motor. By changing the Sine angle (Step through Sine LUT). We...
So the first prototype is coming together. Changed the Brushless motor from a DJI 3510 to an PM2805 with encoder feedback on the Vertical axis. The first version will use a LidarLite V3, here we need a really slow vertical movement @ 0.01 hz and 3.0...
This project picks up where the P1 left off, but with some notable hardware improvements. Blazing machine vision pipeline The Jetson Nano Developer kit has the perfect blend of speed, cost, and connections to make this project something really special. ...
I am currently in the forumlating stages. The current build plan is as follows:1) Find a suitable motor for prototyping: currently considering the MBG36F 36V motor: http://www.goldenmotor.com/2) Find a suitable open source motor driver with...
This board is meant to drive several (the goal is to make the board extendable from 1 to 6+ ESCs) BLDC motors for general use (originally a multi-axis motion simulator). Currently, the board is being designed with the following motors in mind: ...
The body style is a hybrid of a traditional flying wing and delta wing. Eight BLDC motors and rotors can lift the frame clear of ground obstacles. Tilt of the forward drive units will provide thrust. In the centerish of the main body, an auto-levelling...
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...

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...
