1. RLEP – Project Description

2. Needs Break hard soil Chip rock Excavation (ie. Digging, removing regolith) Weight Suggestions for specifications?

3. Spiral Design Model

4. Design Model

5. Where we are now Semester Goals –Improve Mechanical Joints Base Shoulder/Elbow Linear Actuator –Research Soil Properties Devices to break soil Incident Angle Backhoe testing

6. 2 nd Semester Goals –Fulfill design goals –Redesign Current arm –Add force/power sensors

7. Future Design Ideas

8. Problem: Tip not easily replaced might break Flat, hammer like tip Point Cylinder with pointed edge, supports self from breaking off

9. Counteracting break-force Grab ground and hold self down OR: pick up rocks and pile on rover in little container that can be dumped
