Wheel Rocker

Contest Closed
Description:
I want a design for a device that will rotate a wheel about 10 inches in outer diameter about 1 complete rotation back and forth. I prefer for the device to sit on the floor and rotate the wheel back and forth instead of attaching to the carriage frame since I don’t have any carriage specs and they may vary depending on which model is being used The device could attach to the wheel itself, rim or tire. It should be adjustable though to fit on a few different size wheels. It should be designed to be able to adjust to a wheel from 7 - 10 inches.
Wants:
I want it to be a simple and efficient design. The less degrees of freedom the better provided it has the required motion and functions properly. Designs with clear “Design For Manufacturing” capability will be valued more. Inclusion of the following points will also increase probability of choosing your design.
-recommended material
-CAD sketches
-video demonstration
-recommended rotary actuator model part number
-manufacturers
-additional resources


It should be very EASY to install on wheel and set up.

#1 Wheel rocker V01 by Catalin
This is a design based on a small electric motor powered by a 9V battery and a switch that reverse the motor rotation. Is simple, cheap and functional. Between the motor and the wheel for low current consumption and a soft movement there is a gearbox based on an RC reductor. on the wheel there is a pin that after a full rotation hits the switch button changing the electric motor polarization reversing the rotation of the wheel.

Question: do you want to put a baby to sleep with this wheel rocker???? i need to know because if is for a baby it needs also to be smooth and silent....and that complicates things even more

i wanted to upload many renderings but i couldn't cause i am aloud only to upload one photo....so...the answer: the mecanism is fixed on to the wheel shaft ...the entire assembly. If it can be mounted on to the shaft i think that is the best ideea for less money then buying a new electric actuator. i already have a ideea of a cheap and feasible design hand actioned and foot actioned also....i will upload both of them after i am done...thank you for the answer...it is important for me and you also to comunicate if you want a good and complete design. Best regards

It's going to be an electric actuator/motor.

Catalin - I really like the concept, but it's unclear to me how this device will mount onto the wheel? Can you provide a rotated view that shows this?

If you can provide a mechanical hand actioned design that would be great! I'm considering both methods at this point. The mechanical hand doesn't have to attach at the wheel (although it could) rather it could also attach to the middle of the frame as well. Please use your creativity to come up with a feasible design concept.

Thank you.

What type of actuator...electric.....hydraulic??? or do you want a mechanical hand actioned actuator....
The details on this project are not enough to deliver a good quality project.

I'm looking more for rough sketches that depict a concept. I'm more concerned about the concept that the actual intricacies of the CAD design.

Also, the file size is arbitrary. It can be anything, as long as the concept is communicated through the design in a clear manner.

The Detail Required are surely not covered with the Prize money!

17 foot Wood Drift Boat
This contest will be for the most accurate CONSTRUCTION PLANS for a WOODEN DRIFT BOAT HULL. Key features include: 5 piece hull. 5 pieces will be created separately on a table, covered in fiberglass and Kevlar, then stitched and glued together to create the shape of the hull. 1. The Bottom. (1) 3/4" Plascore (honeycomb poly material) measuring approximately 14'6" long X 60" wide. The basic shape of the bottom of this hull will be similar to a "football". However, I would like at least 4 foot STRAIGHT sections running down both sides of the hull (4 foot straight chines). This will aid in the handling of the drift boat. The 14'6" length will be lifted at both the bow and stern ends approximately 5" (rocker). Both the bow and the stern will be identical from one another, so you will only need to draw half of the boat, copy, rotate and attach to finish the plans. 2. The sides. (2) 9mm Okume plywood sides that will measure approximately 18-19 feet long and will range in height from +/-16" to 22" tall. The goal will be to create curved side panels 22" tall in the center of the boat where the oar locks will be attached for a section of at least 1 foot on either side of center. 16-18 inch middle sections for ease of entry into the boat that will gradually slope to meet, and 16" sections at the bow and stern. This should include the end angles where the sides will meet the bottom of the hull, and the bow and stern sections. Obviously all up for adjustment to get the overall shape of the hull to look correct anf for ease of construction. 3. The Bow and stern. This is the difficult part of the boat and the real reason for my contest. To create (2) conical or half-cylinder shapes from 3mm pieces of Okume Plywood that will be bent and laminated 3 times to match the side thickness. This will include the dimensions and angles for attaching that curved transom to the sides and the bottom of the Plascore panels to create an appropriate fit. 3mm Okume can be bent into about an 18" circle, so curves with a radius down to about 8" are possible depending on the grain. I have included a photo of a similar boat hull that has already been built per my design. However, this was done entirely by trial and error and cannot be duplicated. It is also smaller than the specifications in these plans. My goal is to end up with a set of plans that would allow this hull shape to be recreated. NOTE: The interior layout of the boat will be modeled in the future. Additional design work may be possible for the winner of this contest. For that reason, please include a centerline on both axis to use a measuring point for interior layout.
CAD Design
I need a 3d design. Think of a signboard like this: http://theavtimes.com/wp-content/uploads/2013/07/Rave-Party-cancelled.jpg And now we need it smaller and more fashionable. So that someone can hold it like this: https://s-media-cache-ak0.pinimg.com/236x/54/44/a7/5444a7e33dc23f718172ae176a5effca.jpg http://cdn.acidcow.com/pics/20101217/smart_and_creative_31.jpg The pole should be one that can be expanded with the push of a button. The pole will go up to a max of 12 feet. And when no expanded it will be 6 feet. The pole should have 3 buttons on it. 1 button will increase the height of the pole, the 2nd button will decrease the height of the pole. And the 3rd button should lower a stand so that the user can set the sign board down and not have to hold it. Look at this youtube video: https://www.youtube.com/watch?v=85R0_2QGunE You see how the button makes the umbrella open and then close. I want the same the thing. if the person click the button then pole will extend and if they click it again it will go back down Oh also can you make it look kinda futuristic. Do you know what a lightsaber is? Looks like this: http://www.chasing-fireflies.com/cff/137484?SourceCode=WEBGOOGLE&cm_mmc=AdWords-PLA-_-COSTUME%20ACCESSORIES%20%3e%20BOYS%2fUNISEX%20%3e%20TOY%20WEAPONS%2fGUNS%2fNUNCHUKS%2fSWORD%2fSHIELD-_-$10.01-20-_-25765&utm_medium=CSE&utm_source=google&utm_campaign=COSTUME%20ACCESSORIES%20%3e%20BOYS%2fUNISEX%20%3e%20TOY%20WEAPONS%2fGUNS%2fNUNCHUKS%2fSWORD%2fSHIELD&utm_content=25765&CAWELAID=120245380000161201&catargetid=120245380000076529&cadevice=c?clickid=78d14767-1c9f-41c2-890d-cd9a1a6f3f99&gclid=CNWVz4exzNACFYWVfgodMHoD0g So like on the outside of the pole. I want the plastic with the light inside. So it glows. So that it will be strong on the inside, and then on the outside there will be a glowing light to make it look cool On top of the signboard will be a cheap lcd screen. This screen will display text or an image on it. The pole shouldn't be too heavy but it should be strong enough to securely hold the lcd screen on top. The wires should run inside the pole and nothing should be shown outside. I am attaching an image of something really basic but similar to what I am looking for.
The Water Wheel Kayak
We are looking to blend the kayak with the pedal boat. What we want is to recreate the design thought up by Hobie Cat in which they incorporate a pedal design within the kayak. However, we want the pedals to be linked to two water wheels on the side rather than the "fin" system that Hobie Cat uses. (see photo for details) This kayak needs to incorporate a pedal system where people would normally just rest their feet. It would also have to showcase two water wheels on the side. We want the water wheels to be linked by an axe so that they may be easily removed from the kayak if the user chooses to do so. For kayak base use Prower 13 by Ocean Kayak (picture attached). The new design would have A) two pedals where one would normally rest their feet. (see Slayer 13 picture for pedal design inspiration) B) An axe with two water wheels that would be placed at the front the of kayak above the pedals but below the hatch. (See the water wheel picture for inspiration) We'd like the water wheels to be removable and not as bulky as the one in the "Water Wheel picture" What we need- 2 drawings, one from the top, one from the side (just like the slayer 13 picture)
