Pretzel Picker

Ever been deep inside an Autodesk Inventor assembly when hunger just hits you? If you know me, you’d know that I have a strange love for Pretzels. Problem is, sometimes you can’t step away from the computer even for a second or you lose your focus. The Pretzel Picker is a multipurpose robot that can retrieve any desired snack its owner desires that it can fit inside its claw. Couple this with a small netbook with webcam and you can remotely control this recon vehicle around your home, scare your pets, listen in on private conversations, secretly steal the living room remote, anything is possible with the Pretzel Picker. The idea for the Pretzel Picker started with me brainstorming my 2010 Autodesk Inventor Digital Prototyping entry. While trying to think I realized I hadn’t eaten lunch or breakfast so a snack was in order. That’s when the idea hit me, let the robot bring me the snack! The design is effective but simple. Six wheels give this robot plenty of traction, even on the kitchen tile. Also, the four omni-directional wheels allow for tighter turns for getting through doorways. The two-point arm would allow the robot to grab the bag of Pretzel’s from the 2nd shelf in my pantry and the back of the robot is shaped to hold the bag steady as it is transported back to my room. After the good are delivered I would likely torment my golden retriever, what fun.

Truth be told, i'm a SolidWorks guy / obviously 3D Studio Max.

All you have to do is grind bits of magnetic material into the plastic. It's all cool.

@LegoMindstormsmaniac: This was done using Autodesk Inventor 2010. I do use SolidWorks as well, but this challenge specified Inventor specifically. @crawfordsville: Didn't I mention, all of these parts are magnetically charged so they just snap together! Isn't it wonderful. All joking aside, I use inventor to prototype my real robot designs, I never bother with the screws because they don't really add to the design, they just look cool.

Did you use Solidworks to create this?

@crawfordsville, this is not made for the clean sweep challenge, therefore glue, or any other non-vex part, can be used, although, since this is just a virtual design, I doubt that it needs glue to keep it together.
