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...
LongevityThe major consideration for a project like this is how to get it to move and how to make sure it keeps moving. Anyone who runs these distances knows the effort level involved, although a modern electric motor should be somewhat more efficient.Our...
This has been a pet project for about a year now, and I would like to start by giving a short summary of the past design iterations. While having a general idea in my head, I didn't start with a clear end-design. Instead I focused on rapid prototyping...
Current Status I've spent about one year programming the core systems, and one year building, and it is now in the final stages of writing/perfecting the highest level algorithms and adjusting for real-world use. The packet radio interface has...
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...
With the Hackaday 2020 prize drawing to an end (and with my submission video uploaded) I thought it might be a good idea to talk about what I'm planning to do next for the Aruna project. Please note that these are ideas of mine and might not be implemented...
The controller is now ready for testing. Have had to do a few changes to insure good system reliability. * Since the controller can be used as a BLDC or stepper controller, I have upgraded the TVS diode package. * The 5V LDO have been upgraded...
Unfortunately we did not document the making of the Arm/Stepper Motor Control (SMC) and Drive Motor Control (DMC) boards, but they are simple boards that was our first stint into PCB making and therefore contained a LOT of problems that we...
I have finished the design of the new Blade that I want to use in prototype 2. The geometry I got from the QBLADE 0.96 Software which you can download and use for free. I've attached the design and simulation file for my new Blade if you'd like to take...
Stepper drivers are very important for the normal operation of stepper motors and brushless DC motors, so in order to make the motor work better, we need to understand the stepper driver. Today, let us first take a look at the signal output ports...
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...
So as is often the case I vastly overestimated my knowledge on a few subjects. In my last post on this project I had successfully designed and put together my physical motor driver. This meant that all I really needed to do to get the motor spinning...
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...
At its core, the FlexSEA-Execute board is a BLDC motor driver. It is specialized for robotic and prosthetic applications. The high level design goals were to maximize the system integration (small physical dimensions, large number of integrated peripherals...
VESC From Enertion for around $100.00 After about 50 miles using our original Turnig 60A ESC (obviously with no brakes) our VESC finally arrived! Super excited to hook this up.InstallationInstallation was pretty straight forward. We added the female...
