Finger Rehabilitation Device: Prototype Updates and Optimization
This week we worked to update the initial prototype and fix some of the initial problems such as the finger caps not fitting tight enough and the resistance bars bending sideways. The finger caps were …
Constant Velocity Joint Prototyping
Some of the iterations of our prototype builds can be seen below. The most current prototype, seen below, was an improvement upon our previous models in that it had clearances of 0.5 mm between the …
Finger Rehabilitation Device: Prototype
Over the past two weeks we have created a prototype of our finger rehabilitation device. This included a plate that fits to the palm of a team member’s hand, thumb and pointer finger caps and …
Fidget Cube First Prototype and Assembly Evaluation
When the all the parts for the first prototype were finished, there was some difficulty with the assembly of the fidget cube. The tolerances for the the frame where a very tight fit especially for …
Bucky Assembly Evaluation (…Again)
Hello, The previous post discussed our second attempt to produce a movable joint Bucky. While we were technically successful meeting all of our design goals, we weren’t quite satisfied with the end result. The joints …
Constant Velocity Joint Optimization
Hello, This week our group focused on getting the internal portion of our constant velocity joint to print as an assembly. We found that we needed to increase the amount of clearance we were working …
Bucky Assembly Evaluation
Hello, After our first prototype (discussed in the previous blog post), we realized we made some critical mistakes. This post will discuss our next attempt to print a full motion Bucky. Second Bucky Prototype (Bucky …
Fidget Cube Report
The redesign and optimization of the dumbbell slider resulted in the print in Figure 1. The original model had a small dumbbell diameter that easily broke, so this version was fortified by increasing diameters by …
First Bucky Prototype
Hello, We have been busy making alterations to Bucky these past few weeks. The following three blog posts will discuss the different designs we used and changes made for each version. First Bucky Prototype (Bucky …
