HEW-DV4 a lasercut desktop robot arm by Nightxp

Last crawled date: 3 years, 4 months ago

This is HEW-DV4 (design version 4) a robot arm designed for desktop use created from scratch. The idea behind it was to designed and build a friendly, easy to use robot arm so that hobbyist, makers and education alike can have fun building or simply using a ready out of the box robot arm. His reach and repeatability make him quite useful for most hobby uses.
After finishing university in 2011, I found that the current day robot arms for hobby use where too expensive and lacked a lot of features and had poor quality/specifications, So I designed my own.
With this design the flat file (ready for laser cutting in mm dimensions) you can simply laser cut all the parts from 3mm acrylic and be ready to go in no time! I've included the full BOM list (Bill of Materials) as well as the assembly instructions, so any one can find the parts required to make your own.
I finally want to give HEW to everyone without any price tag as I closed my 1-man startup down in 2017.
I hope you have as much fun building and using him I as did making him.
Notes:
Requires 3mm acrylic of any cololur!
Servos used are the official TowerPro servos which have an embedded TP in the plastic bottom (knock-off versions are vastly weaker and may include plastic gears!)
The racer bearing isn't fully needed but helps out a lot
**Grippers (End Effectors) uploaded into this design now (was going to upload them separate but decided to include them on this design)
** Added assemmbly guide for grippers, simpgrips / simply gripper, magnet gripper and GoPro gripper
**Added .stl files for 3D printers!
