Yes! In fact, our 2 pin designs use less material and have other benefits that make them a preferable choice for most applications. Our demonstrations show the 3 pinned system because the specific designs for a reliable 2 pinned system are currently still trade secret. Please contact us to discuss.
The Rotolatch™ system was originally designed to be easily injection molded. Our cost-optimized latch design is a two-piece assembly. We have not invested in molds because our 3D printed PETG parts work just fine. Rest assured, our injection-molded part design was created by an experienced plastics designer and licensed professional engineer. We expect an injection [...]
The hooks can be injection molded for between $0.02 and $0.08 depending on material and load requirements. We have hook designs for minimal material use material to reduce cost and environmental impact. The boxes may require an additional cut-out and assembly step, which will also increase the cost of implementation on a package. Also, box [...]
Yes. Disengagement requires a differential, vertical force between the hook and the latch. On a drone carrying a package, this means the package would need to experience a significant upwards force that does not also push the drone upwards, or the drone would have to move downwards at an acceleration greater than gravity. While we [...]
Our current system has been tested to engage 1000 consecutive times without failure with an axial offset of 1cm. We believe this is plenty of flexibility for most automated systems, but the geometry can be tuned to increase reliability at larger axial offsets for specific applications.
