3D-printed Robotic Arm Gripper

Some initial pictures from a robotic arm gripper I designed using Onshape and 3D-printed on Makergear M2. I am using inexpensive micro hobby servos. I am able to activate the gripper using a servo tester but need to adjust the dimensions for smoother motion. As I build rest of the arm, I also plan to change the shape of the tip to provide more clearance.

World Maker Faire 2015 at the New York Hall of Science

September 26-27 was the 6th Annual World Maker Faire at the New York Hall of Science (NYSCI). There were individual sections for robotics, drones - with a "drone cage" for demos, makerspaces, 3D printing, STEM education, startups, dark room for light-related projects, arts and crafts and many more interesting projects spread around the NYSCI, indoors and outoors. You can see the full list of projects at the 2015 Meet the Makers page (scroll down to search by a keyword).

Here are some pictures I took:

"The Lumiphonic Creature Choir" was a very interesting installation. The dynamic twelve head displays are generated by a projector, and a keyboard controls whether they talk or stay silent.



The "Dark Room" hosted light-related projects.



There were multiple automated musical instruments.





Separate section for drones had a large space enclosed with nets.


There were various robotics and remote-controlled vehicle projects.










The "Mid-Atlantic Retro Computing Hobbyists" had a great exhibit with older computer equipment. Here's my favorite, a Commodore 64 with a 5.25" floppy drive and you can even see an Amiga on the corner of the picture.


There were many 3D printed projects.




Speaking of printing, here's a pancake printer!


The "R2 Builders Club -East Coast", had not just one but a group of R2-D2's.


There were a number of building tools such as for PCB manufacturing and CNC milling, in addition to multi-purpose tools with changeable heads.






Here's a 3D scanner that uses your cell phone for scanning,


and a DIY satellite ground station system.


There were also some kinetic sculptures.



Finally a few pictures of the NYSCI,



and the Unisphere at the Flushing Meadows Park, where the visitors boarded buses to go back to the parking lots.
