Well It almost worked
Log from 3D Printed Chiming Clock
I printed a copy of the Escape Wheel and the Graham Yoke to test how well it would work. Well it mostly worked, but would occasionally hang up, and was quite rough in spots. So I decided to go back to basics and redesign both the Yoke and the Escape...

Whoomp! (There It Is) v0.4 that is!
Log from MeArm - Your Robot
So here it is! And here it is http://www.thingiverse.com/thing:360108 v0.4 all the tweaks previously mentioned rolled into an improved version. This is where the mechanical tinkering will largely park for now. Although I was looking at the gripper...

Uneven Bevel Gears
Log from 5+ Axis Robot Arm
Here's a close up of the gearing in the wrist. Everything here works in theory, but needs to be proven in reality. I tried printing some of these gears.The cap on the bottom is a test fit for the rotation sensors.Turns out these gears don't mesh correctly....

Ivan Arm Revisited
Log from Ivan the Teambuilt Robot
This is a design I created tonight. It's based on NEMA17 motors, since I have six of those from an old 3D printer I took apart. The idea is to make it as fully plastic as possible, with as few fasteners as possible (if any). I know the rotations aren't...

Ivan Arm Revisited Again
Log from Ivan the Teambuilt Robot
I realized a simplification in Ivan's construction by thinking about the bearings. These are 3D printed all-plastic bearings made of planetary gear sets, most notably AVA's Gear Toy 2 which you can view here. That's a two-to-one gear reduction from innermost...

Experiment in Wheels: Part 4.
Log from Micro Robots for Education
Hello, So it seems the core issue in this project is how to reliably make the wheels. The resin 3D printer I used before made some ok wheels, though the tolerances where not reliable, also as the optical path became foggy the quality of the teeth degraded....

I did it, I designed a gearbox assembly to get rid of that pesky belt
Log from Mr Pancake
So, I figured out how to do gears in Fusion 360 and I made a prototype of a new mechanism to transfer power from the stepper motor to the axle and combined it with the mount for the x axis rail.I've still got a few more bits left to sort out, I have...

Drive and angle measurement considerations
Log from Low cost Robot Localisation System (LRLS)
The SRLS determine the position only based on an angle measurement. As further the robot is away as more demanding such a angle becomes. E.g. the robot is 5 meters apart from the SRLS one degree of error result in a 9cm positioning error. This isn’t...

Better modeling
Log from 3d Printing real-world keys
Until now, I had been using SketchUp and manually editing a key model. Obviously, it wasn't precise enough so I decide to give OpenSCAD a shot. OpenSCAD is a programming environment where the code deals with manipulating 3d models. It can export .STLs,...

Z axis belt clamp fail...
Log from Belt Lifted Z-Axis for a 3D Printer
The Z axis was recently behaving strangely. I noticed the belts were flopping around so I retensioned them. In a couple days, they were flopping again. I took them off the machine to see what was going on and instead of finding that...

CAD Changes 13.09.2018
Log from 3D Printed Strain Wave Gear
I just updated the CAD-Files. Now the Circular Spline and the housing are two seperate entities, this allows for a fast iteration on tooth profiles as one doesnt need to print the biggest part of the assembly over and over again. Instead of a dovetail...

Quadruped Tail
Log from Low Cost 3D printed Robot Tail
Last year I started a new, light 3D printed quadruped using cycloidal gearboxes. It now needs a tail. The first design was based around standard RC servos but it was a bit boring. Does there need to be a good reason??? It was a bit slow, lacked torque...

I can't be that lucky..
Log from MPRT - Modified planetary robotics transmission
For kicks I decided to add an idler gear. This is one way to prevent the output ring from pushing in on the planets. Either I'm incredibly lucky, or there must be something happening with the math here that I don't understand that makes this...

Self Aligning Mating Gears
Log from Multitool 3D Printer - Blackbox
The new tool changer uses the Bondtech Extruders 1:3 reduction to decouple the extruder from its motor. To make this work, the gears need to be aligned at any time (which sounds easy but it's complicated with open-loop stepper motors). Another solution...

Assembly notes
Log from Simple Thermal Camera
Two unused mounting points in the "top" of the case need to be removed to provide clearance for the screen.The top of the case also needs holes for the switches, and a big rectangular cutout for the screen. Start with smaller holes than you think you...
