Walking Robot - Initial Sketches

These are our initial designs for the walking robot. This is our horse-bot, we had initially looked at a six legged robot. First, we made the six-legged model on legos. We then modified it enough to come up with a design for the four legged horse-bot. It will use a DC motor to turn an axle which moves the entire robot.

This next design is aquatic and is dubbed the froggy. We it makes use of a servo motor that moves the legs back and forth. The legs are designed so that they bend in one direction but straighten in the other direction. This way as the legs go out, they bend and as they come back in, they straighten and push the water out.

This design is the spiral tail. It is a number of plates along a teflon rod. The plates would be placed so that they create a spiral pattern down and along the teflon rod. Hopefully, as the wheel turns, the spiral pattern will push the water out.
This is the scuttle bot. It was inspired by a crab. We were trying to figure out how to make a side walking robot. The bet we could do is this. We would have two squares on top of each other and the top one would be connected to a servo motor. The feet would only move in one direction and the robot would "scuttle" back and forth.
This is a simple rower, thus it is called the rower. It uses a DC motor to turn two circles and it turns the oars in a circular motion. The one concern that we had was whether or not the teflon would float on the water and whether or not we would actually be able to make a "boat" out of teflon.
