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 rotary actuator model part number
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.

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.
