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!
