harmonic drive robot arm 3d models

Prototype of harmonic drive, used to drive a robotic arm.

My goal was to implement the principle of the harmonic drive into a sturdy solid module that can ultimately be used for making a robotic arm. This is my first prototype, and it works quite nicely.http://youtu.be/D_neLbcW_BY The circular spline has 84...

harmonic drive i made, uses 7.9 mm steal ball bearings. ...make sure to split into parts before printing

See more details: http://www.projectbiped.com/projects/harmonic-drive Check out the video of the drive in action: http://www.youtube.com/watch?v=vF3HHH-Et4c Instructions Harmonic drives are used on a lot of the high end humanoid robots such as Asimo....

A harmonic drive is a very simple gear reducer that lends itself well to 3D printing. It uses a rigid outer gear and an inner flex spline. The flex spline has a few less teeth (typically 2 less) than the outer gear. You stretch the flex spline...

... in a wave form, almost moving like a serpent... it works rather strange and funny, but they are used in high tech gear applications. more info : http://en.wikipedia.org/wiki/Harmonic_drive animation on : http://www.youtube.com/watch?v=lstQwLbAG0g

Harmonic drives are mechanical gear systems that have some very nice properties such as no backlash, high gear ratios, and being able to hold their position without power : http://en.wikipedia.org/wiki/Harmonic_drive Harmonic drives have an...

This is a harmonic drive for a nema 17 stepper. You need a few parts to complete this. 4 M6 x 10 or 12mm long Button head cap screws. (wave generator) 4 x 606-2rs bearings (wave generator) 24 x M3 X 16mm Flat Head Cap Screws (at least 12) 4 x M3 X...

This is a tri-lobe harmonic drive (because why not ?) Here are the videos where I talk about it :https://www.youtube.com/watch?v=yehE7aFYUGUhttps://www.youtube.com/watch?v=ajxFor8MDcA Thing comes complete with its solidworks source. Also available on...

It is a type of harmonic drive, which uses a flexible output ring to attain a high gear reduction. My design is unique (as far as I know) in that it also incorporates a planetary gearset for further reduction. Instead of a toothed belt for the...

Pneumatic drive

This is a community project based on ftobler's robot arm design. The design has evolved additional hardware designs, functions and hardware in the past 2 years. The PDF contains BOM and assembly guide which helps new builders to get familiar with...

Harmonic drive mechanism for robotic head

Simple telescope mount using two CSF-14 and two CSG25 harmonic drives. ...Uses Nema 23 stepper motors with encoders.A variety of gear reductions can be attained depending on the harmonic drive section.

I had some time on my hands today, so I decided to take on a project I’ve been wanting to do for a while; a Harmonic Drive that would be feasible for an FRC robot. The design I came up with has a gear reduction of 125:1 and uses a GT2 3mm pitch...

Great for giga pano's or video. ...Two csf-11-30 harmonic drives and 2 nema 17 26:1 stepper motors. ...Use any controller that supports steppers.

3d printable Harmonic Drive for Steeper Motor(Strain Wave Gearbox) with 1:25 reduction steeper dim-42*42mm steeper mounting pcd - 44mm

I designed a compact 3d printable harmonic drive gearbox. ...Below is a video with an explanation Video: https://www.youtube.com/watch?v=9sv-3hSR8XQ

The harmonic drive has the option to mount a potentiometer/encoder which makes the actuator closed loop and allows for precise position control. A simple PID controller can be implemented to go from open loop to closed loop. ... Feel free to message...

Lightweight telescope or camera mount. ...Uses two csf-11-30 harmonic drives. And two Nema 17 26:1 steppers Has a Pole Master polar alignment scope on it. ...Put on a wedge and gain a GEM or use as a ALT-AZ mount

This is a harmonic drive designed by a great youtuber called @3DprintedLife I recommend you checking him out. He put this design on Github but not on Thingiverse, since Github can be a little bit scary for some people I decided to put it on...

Harmonic drive ratio- 1:100 (can be increased)Spur gear ratio 1:5This combination has much higher efficiency than combination of worm gears and multiple spur gearsDepending on the assembly requirement 3 spur gears can be used instead of 2 to open up...

There are two types of harmonic drive (STL and Fusion360 files), one only has 2 contact bearings but has adjustable tolerances, the other has a full set of 8 contact bearings but the tolerances must be modified in Fusion360. I used the one with two...

50:1 Strain wave gearbox (Harmonic Drive) This is my prototype for a harmonic drive. Based on my tests this design has minimal backlash and is backdrivable. It's a bit big for what it does, so I'll be revising it for a more compact design. You'll...

I'm using it as the drive gear for a turntable for photogrammetry.Assembly is straightforward, I hope: put the servo in the motor cage (from the top, wires first: it's a tight fit and you need to be careful not to damage the wires on the cage); the...
