"Claw Machine" Concept

Criteria:

• Box is max 20cmx20cmx20cm and 2kg

• Probably not less than 20cmx10cmx10cm

About the design:

• Uses flexible PETG to wrap around the object

• Similar to a claw machine it would allow us to lower the package into the barrel

• meant to ‘scoop’ up a packet while deforming around it for stable conditions

Specs:

• 3D printing ~60 grams

• Linear Actuator: 88$, 2” stroke, 90.7 grams, water resistant

• Stronger Actuator: 56$, 2” stroke, 70 grams, not water resistant (no cad)

Mechanics:

Minimum grip ~0.5in

Open

Maximum grip ~9in

Open

Grip size can be adjusted easily based on requirements.

Feasibility:

• Currently the lower arms aren’t rigid enough to support 1kg. I’ll increase the thickness and re-print

• Lower arms have good flexibility to wrap around shapes from 2” to 6” which includes rectangular and circular objects

REV 01

• More claws = more grip. May have to upgrade to a 15lb linear actuator

• Testing 5mm lower claws to see if they have a good amount of flex to stiffness

• Same grip size
