Autodesk® Inventor® 2010 Digital Prototyping

Using Autodesk Inventor 2010, design a VEX robot that can do a household chore or activity falling under one of the following categories: necessity, convenience or entertainment. If you don't currently have Autodesk Inventor, you can download a free* version of the software on the Student Education Community at:



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...

Piano Playing Robot


*This is not my actual description! Please see Word Doc.* My entry for the Autodesk Inventor competition is a robot that can play the piano. I enjoyed working on this entry from the idea to the entry process, and every step in between. I want to give a special thanks to Autodesk Inventor as it was very useful in the completion of this entry. The robot was made to be as realistic as possible, with everthing down to the screws and nuts. Please note that I even added the new LCD display. I hope everyone enjoys this robot and good luck to all of the other contestants!

VEX Robotic Compactor


Have you ever been sitting in front of the TV, cleaning out your backpack, when the trash can somehow runs out of space? I have, and the only solutions I could devise were to either stop what I am doing and crush the paper with my foot or carry the bin to the dumpster and dispose of the trash. Both of these tasks required work, and neither is entertaining nor fun. My solution is the VEX Robotic Compactor. It uses high torque to generate enough force to compact the trash, so that fewer trips to the dumpster are required. Then, when I do have to take it over to the dumpster, I can drive it...

Are you tired of forgetting all of those Saturday chores? Well look no further, the Reminda-tron will help you stay organized and complete all those chores. This simple designed robot has three erasable white boards that allow you to customize the to-do list to fit your needs. When you complete one of your tasks, just press the red button and the robot will rotate the board showing the task has been completed. Do you have more than three things on your to do list, then just add more Reminda-trons. Don’t trouble yourself trying to remember what you have to do, let the Reminda-tron do it for...

Vex Knife Sharpener


The Automatic Knife Sharpener Inventor: Jacob H, grade 8 The use of this invention is to make knife sharpening easier, quicker, and much safer. It was created to help anyone who uses knives frequently like chefs. Or anyone that is bad at sharpening knives or doesn’t know how to. My knife sharpener works better than a human because my device provides a linear motion instead of a humans jagged arm movement. The Automatic Knife Sharpener consists of the Base, the “Cart” and Arm. The “Cart” consists of the “arm”, the knife, one motor to supply the power, and the pinion gears. The...

Room Cleaner


Have you ever been hard at work on a robot and suddenly get told to clean your room? You cannot leave what you are doing or you will lose your concentration! What should you do? Get out the Room Cleaner. The Room Cleaner is designed to autonomously clean a room by picking up small objects on the floor. It has a high power claw (150 Lbs of force at axel, see picture below) for picking up objects and a trailer to bring them back to you. It utilizes four motors, one ultrasonic sensor, and one bumper sensor.

Eagle Engineering, 1138, worked together to plan out a new design for the classic problem of trying to be in your own video or including everyone in the video. Not only have we brainstormed the robot and built a model in Autodesk Inventor, but we have gone the next step to build it out of VEX parts.

VEX Game Clock


During a VEX Competition the spectators often struggle to see how much time is left in the game. Our VEX Game Clock will stop them from ever wondering again! Measuring a whopping 2 meters long by 1 meter high it will be visible even from the other end of a football field. The VEX Game Clock counts down in the same way as the clock on the Game screen but in a much cooler way. The noise when the time flick over is like a whole lot of robots on a game field. The clock is started and stopped automatically by the field control stuff.

Toilet Bot


Toilet cleaning. The worst chore in your house. Nobody wants to do it. Is there a better solution to cleaning the toilet then having somebody do it? Yes there is! Call in the Toilet Bot. The Toilet Bot is a VEX robot designed to, when activated, autonomously clean the toilet. All you need to do to set it up is put the brush in the claws, twist the axel to tighten, and tighten the shaft collars to hold it in. It is programmed to sit next to the toilet until the bumper sensor is activated. Then, it raises the brush, moves the brush forward, and lowers the brush into the toilet bowl....

Neat Freak


Have you ever found your self in the middle of an intense video game only to find out that you had "forgotten" to sweep the floor, or vacuum the carpet? Then the Neat Freak is for you! The Neat Freak has flaps on the front that spin debris onto a plate, the flaps and plate can tilt so that they always stay flush with the surface. Once the plate is full, the Neat Freak can flip all the debris on it onto a tray, and once the tray is full, it can be easily removed, and the debris disposed of. The Neat Freak is driven by a holonomic drive train, which allows easy maneuvering in any...

VEX Sizzler


During a New Zealand summer it is a common custom to invite your friends and family for a ‘bring-a-plate’ barbeque. Everyone who is invited will bring a plate of food whether it is meat or sausages to be cooked, or a side dish. This saves the hosts from preparing large amounts of food for everyone, but it does mean the host will still end up standing over the BBQ cooking the meat, unable to join in with the party.

As is inevitable on most VEX Robotics teams, Team 254 members have found themselves working on their robots late at night...often without a heater, and never with one in reach. To solve this problem, we thought of the most efficient, user-friendly way to move the heater – and came up with Heaterbot. We planned for Heaterbot to use a holonomic drive. This drive system would let the heater move freely around as well as rotate in place. We also aimed for a central spooling mechanism which could wind the extension cord connecting it to the wall. After talking with the 254A programmer, we...
