FlexSEA: Wearable robotics toolkit
Details from FlexSEA: Wearable robotics toolkit
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...

ROSCOE - A Scalable, Platform Independent Robot
Details from ROSCOE - A Scalable, Platform Independent Robot
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...

(Short clip of driving outdoors) OverviewAs before, this project is about making a "drone-like" model car which gives the operator a video feed, some telemetry, and which communicates with a single digital radio. At the heart of it is a Raspberry Pi...

Arcus-3D-M1 - Full Color Filament Printer
Details from Arcus-3D-M1 - Full Color Filament Printer
This project has reached its logical conclusion with all further development now continuing on the Arcus-3D-M2. Being born as a junkstrap, it inherently had a large number of variables to try to account for which was slowing development. Now that a clear...

Powerful Brushless DC Motor Driver/Controller
Details from Powerful Brushless DC Motor Driver/Controller
The Power PACks are modules designed around the PAC52xx family of devices and are all meant to drive motors of different topologies, sizes and algorithm styles. All of these modules are very similar in construction, albeit there...

MPRT - Modified planetary robotics transmission
Details from MPRT - Modified planetary robotics transmission
Using it! I've decided I need a transmission for testing out the #FilaMecanum concept, so this is going to be it. Background First I think I need to explain how a normal planetary drivetrain is constructed. The power input...

Teardown: Xiaomi Mi Vacuum Cleaner Mini (EU)
Details from Teardown: Xiaomi Mi Vacuum Cleaner Mini (EU)
In the top of the device, there is a plastic cap holding the motor in place. I undid the three clips by squeezing the device to allow for a bit more wiggle room, then prying with a flathead screwdriver. Under the plastic cap there is a rubber thingy,...

HoloLamp - Between display concept & physics class
Details from HoloLamp - Between display concept & physics class
Why? I was curious to experience how it looks and find out if it works. It might also be a slightly more engaging alternative/addition to showcasing the uncertainty principle with two razor blades and a laser. How did it turn out? Better than expected....
