Task Description
Proximity limit switches are used as end-stop failsafe triggers on each of the arm joints
These sensors send a high signal when a ferrous metal is detected within its sensing range
On axis 4, there is currently a placeholder proximity limit switch mounted but no dedicated piece of metal or feature to trigger a sensor pulse
This task will require a designer to assess the current position of the limit switch, determine if there is an appropriate trigger that can be installed to trigger a high signal 360degrees, and potentially redesign and reinstall a sensor mount / trigger
The current location of the proximity limit switch is not finalized and can be moved at the designers discretion

Task Breakdown
- Assess the current position of the sensor mount in CAD (determine if there are any potential interferences)
- Determine if a sensor trigger can be installed on an interface on the forearm (A5/A6)
- Determine if the proximity switch needs to be located
- Update arm CAD with sensor mount/trigger concept
- Propose design idea for switch + trigger to mechanical lead
- Update the design as required
- Fabricate all required components, install on arm
