We drew prototypes of containers at first.

Then, for the modeling subteam, built a model of one another's prototype:

After that, came up with different constrains, objectives and functions that we need.

Objective:

• The prototype is easy to use, also easy to pick up by robotic arm.
• It is not fit the footprint well; it might be too heavy.

Constraints:

• In terms of the large size, it may be over 350g.

Functions:

• The prototype can hold the surgical tool, and also can be picked up by robotic arm.

Then, we built the model by using autodesk inventor.

Came up some suggestion to make the model better.

Suggestion 1:

• Increase thickness of all dimensions. In order to increase durability of the container, we must ensure no part of the device is easily breakable. To do so, an increase of thickness will increase the fortitude of the walls so it does not easily break under pressure.

Suggestion 2:

• The grab area is not easy to be hold by robotic arm. Change the grab holes to be slightly larger, making it easy for robotic arm to pick it up without slipping. Possibly add extra notches for the gripper to slot into within the side holes.
