OSHE Week 5 Update
Figure 1: Rough Sketch of Recyclebot
Figure 2: Diagram of Recyclebot states
- States
- On
- Empty spool placed on spool mount
- Cage is closed at all times
- Sensors sending constant feedback to respective components
- Power sent to each electrical component
- Each component operating within specified thresholds
- If thresholds superseded or Cage door opened E-Stop initiated
- Only motor shuts down when E-Stop active
- If thresholds superseded or Cage door opened E-Stop initiated
- Off
- Power is not sent to electrical components
- cage may be opened or closed
- No mechanical movement occurring from motor
- Extrusion barrel may be hot still if E-Stop was recently triggered
- On

OSHE Week 3 Update
To Do List
- Begin developing ideas and designs for vacuum chamber and safety measures
- Research vacuum chamber functionality and component requirements
- Review current E-STOP for Recyclebot
- Research examples of E-STOPs for redesign
- Continue creating BOM
- Discuss with team current designs for the main units and potential hazards with the design
- Research safety precautions for discussed hazards
- Research how filament is currently manufacture to compare to Recyclebot
- Specifically how filament is cooled and wound onto spools
- Construct drawings and schematics for vacuum chamber
- Acquire certification for soldering in OSHE Lab
Concerns for Next Week
- Finding time to discuss with full team about plans moving forward
- Breaking the vacuum unit into different components to be discussed
