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...
You can find the schematics and PCB in the link below : The sample code : https://github.com/Navid-Sabet/Dog-robot/tree/main/BLDC-driver/3pwm%20single%20module/SW/bluepill_focThis code is based on simpleFOC library and Arduino STM32 firmware. With sending...
Story Almost every Raspberry Pi enthusiast tries their hand at motion at some point—whether it's moving, sliding, or rotating objects. The most straightforward and economical method usually involves using servos. However, it doesn't take long to realize...
This example shows how to control motor speed, torque and angle of BLDC gimbal motors using the Field Oriented Control (FOC) algorithm (or not) in C++/Python. "A Guide to Using BLDC Motors (Gimbals) with OpenSource PCB SaraKIT: A Comparison of Stepper...
If you are interested in BLDC driver from this project fill this form: https://forms.gle/eHPAsbJ77hMaUC4FA Goal of this project was to create gripper that could sense forces by measuring current thru BLDC motor. It is based on my S-Drive BLDC driver...
Necessity : I wanted to learn ( + build + experiment) quad-copter dynamics. A tweak-able quad-copter is expensive. A friend of mine bought one for ~$500. I analyzed that the major cost of quad copter comes from Radio controllerBLDC(+ ESC)Electronics...
The Tiny BLDC board measures 1.3" x 0.9" (33 mm x 23 mm). The reason why we can make a BLDC motor driver so small is because PAC5223 has pretty much all the circuitry required to drive the power FETs. These components are:3 phase pre drive power stage3...
he basic idea behind the Preloaded Hydraulic Muscle is to use two inflatable bladders and keep them partially inflated in the idle state ( t. A gear pump transfers the fluid from one bladder to the second one moving the actuator. Each of the bladders...
Story I've always enjoyed building with Lego bricks, but rather than following the provided instructions, I preferred bringing my own ideas to life. Recently, I've delved into the world of Raspberry Pi, appreciating its capabilities, as well as being...
Find out more at: https://source-robotics.com/ The Problem Today every engineer, maker, and tinkerer can get access to a decent 3D printer for less than 300$ and start creating. Many of those people that have 3D printers also want to play and experiment...
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...
Printed in PLA from Filaments.ca, the brace from the tower to the vanes was easy enough to fix... but why just repair? I made it betterer. I also upgraded the stock BLDC to one about 20% more powerfuller (2212 2200kv) and put a triple blade (5x4) prop...
The main goals of this design are:Design has to be cheap(ish); parts i can get for free through contacts won't be seen as costs, as is stuff like the water-jet cutter i can use for free at my university. Can fit under my bed for storage when not...
