Patent number FR2910833-A1/WO2008080917-A1 is of interest to us. It is another hand oriented Cable Suspended Interface. The user would hold onto a joystick like device and be able to control an object in 3d space. It seems like this report spent more time focusing on the dynamics and increase visibility than […]
We are still in the process of making our design easy to fabricate. The option that requires the least thought is to 3D-print the whole assembly, but that option is expensive. The department charges $5.50 per cubic inch to 3D-print for senior design. This cost includes support material. Using the […]
Milling pockets for servo mounts seems like a good idea in Creo, where everything is a right angle. But let’s see what happens when one tries to mill this pocket with an endmill long enough to get to the bottom of the pocket. I have a funny feeling that […]
Instead of placing the motors on the metacarpal, that area can be covered in rubber. Using wires instead of linkages, the motors can be mounted to the upper arm, reducing the apparent weight of the system.
I would just like to share an update on the redesign. It had to be retired. It was simply not manufacturable in the MechE shop. The 0-80 screws needed were not compatible with the 3d printer’s tolerances. I also wanted to share a nicely finalized part. Creo is […]
While CADing I found the original design of the finger joint to be clunky. The 3d printed joint body (yellow) holds a pin (orange) which is held in place with a 1/8 thick piece of laser cut acrylic sheet (red). This acrylic piece is then screwed in. The pins added […]
