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

2nd Semester Goals

– Fulfill design goals– Redesign Current arm– Add force/power sensors

Future Design Ideas

Problem: Tip not easily replaced

might break

Flat, hammer like tipPoint

Cylinder with pointed edge, supports self from breaking off

Counteracting break-force

Grab ground and hold self down

OR: pick up rocks and pile on rover in little

container that can be dumped
