Water Walking Machine

The Water walking machine is a device that combines the elements of water resistance with a low impact aerobic workout. It’s a great choice for people who are not able to do traditional gym and weight training exercises due to injury, disability or health conditions.

It can also improve balance and gait, increase leg strength and help someone recover from a stroke or other injuries.


Water walking is a method of exercising one’s leg muscles. It is a great way to tone up the inner and outer thigh muscles, but it can also be used to strengthen the lower body, such as the glutes and hamstrings. There are many different variations of water walking that can be done in a pool or lake, and some may require weights.

Water walkers are typically constructed with a pair of buoyant hulls 20 with propulsion flaps 22 mounted on the bottom, and a footwell 30 containing resilient shoes 32 attached to the footwell. The hulls are longer than they are wide, and the footwell is located in each hull so that the user’s feet are near the center of gravity and below the waterline.

When the user steps on one of the hulls 20, the flaps 22 fold and form cup-like resistance chambers in the hull to offset the rearward force caused by the users walking stride. When the user lifts his foot from the hull, the flaps 22 and fin side panels 54 rotate inwardly to propel the user forward.

In addition to the propulsion flaps and the fin, each hull 20 has a scoop 63 at the front of the hull to facilitate the flow of water under the flaps 22. The fin side panels 54 are hinged to rotate inwardly when the hull is urged forward, and these rotations help to offset the rearward force caused by the walking stride and propel the user forward.

A further feature of the device is that a novel footwell 30 is formed in each hull and is narrow enough to fit one’s foot in. The bottom of the footwell is below the waterline and near the center of gravity so that the user’s feet are stabilized as the device is being pushed forward.

The footwell also includes a wingnut 48 and thumbscrews 50 which can be attached to the resilient shoes to secure them in place. The wingnut and thumbscrews can be removed if the user wishes to disassemble the device for storage or transportation.


Water walking machines are designed with a variety of stability measures. For example, they have a footwell that penetrates the hull to a depth below the water line near the hull center of gravity and is narrower at the top than the bottom such that a person’s foot may enter and yet provide support for a person’s ankle, thereby decreasing the susceptibility of tipping.

Another stability measure is Landing Accordance Ratio (LAR). It considers the time difference between the moments of feet in the same phase touch down and the moment of impact with the ground. It can be a more accurate criterion than the leg-end-supporting moment or the tumble stability margin in evaluating the stability of a robot’s motion.

Several dynamic-stability criteria have been proposed to address the limitations of static-stability criteria. One of them is the Water walking machine virtual-support plane. This criterion uses the position of the previous support foot and that of the next support foot to determine the position of the virtual-support line. In particular, this criterion is useful for gaits with multiple support feet such as trot, pacing, and bounding.

Other stability criterion are based on the resultant moments of the legs and the supporting boundaries. These include the leg-end-supporting moment (LSM) and tumble stability margin (TSM).

A number of other methods have also been proposed to evaluate the stability of a robot’s motion. Some are based on the Lyapunov theory of switching systems. Some others are based on energy-based principles.

In addition, some stability criterion include a joint-driving torque that is the force needed to maintain the rotational balance between the body and the ground. These criterion are applicable to a wide range of motions and have a high accuracy.

Stability of a water walking machine can be evaluated using the traditional ZMP criterion, LAR, or the new stability criterion for trotting gait of a quadruped robot. The quadruped robot with trotting gait was tested by applying three impact forces parallel to its CoM in a series of tests (Test 1, Test 2, and Test 3).

The results of these tests show that the motion of Test 1 is more stable than the other two. However, the motion of Test 2 is the least stable since the robot tumbled after the first impact. Moreover, the robot lost its stability after the third impact.


Water walking is a great workout for people of all ages and abilities. It is low impact, does not put any pressure on your joints and can help to lower blood pressure. It also helps to strengthen muscles and improve balance, making it a valuable addition to any exercise routine.

To improve the intensity of water walking, many fitness centers and gyms have equipment that allows you to increase the resistance as your arms and legs move through the water. Some of these exercises include wrist weights, foam dumbbells and resistance gloves or hand webs.

Another way to add more resistance is by using ankle fins or a water resistance parachute. These devices will help you focus on your lower body, and can be used for a wide range of exercises such as hamstring curls or leg raises.

Those who are recovering from knee surgery or have other mobility limitations may want to skip the leg machines at the gym and use these ankle fins instead. They are an excellent way to condition your leg muscles and will get you to your goal quicker.

A number of different designs for Water walking machines have been developed. Some of them are very simple, while others are more complex.

One simple design includes a pair of buoyant hulls that are longer than they are wide, with a number of propulsion flaps mounted on the bottom. When the flaps are hinged open, they fold into the hull creating cup-like resistance chambers that offset the rearward force of the wearer.

This design is able to achieve speeds of up to 5 miles per hour, and can be operated by a single user. The device can be used by anyone with balance issues or other mobility restrictions that prevent them from standing up on their own.

Some designs of Water walking machines even include a footwell and a resilient shoe that can be positioned in the footwell to give the user greater independence in the water. These designs are very popular with swimmers who use a walker, crutches or cane as well as those who have balance problems and are recovering from surgery.


Taking a watery stroll on the beach is the newest trend in exercise, with fitness enthusiasts using a variety Water walking machine of gadgets to make the experience more enjoyable. The Water walking machine is one such device that combines the latest in aquatic technology with a touch of magic to make the process easier on the human body, while achieving the desired results.

The novelty of a Water walking machine is that it can be used by individuals with varying degrees of mobility, and even those recovering from surgery. It is also useful to those who simply want to have fun, or enjoy the fresh air without putting a damper on their active lifestyle.

A high tech approach to this challenge involves a pair of buoyant hulls, longer than they are wide with a number of propulsion flaps mounted on the bottom. The flaps are the ones that make the most awe inspiring claims, as they fold into each other creating cup-like resistance chambers when hinged open to offset rearward motion of the wearer allowing them to be propelled forward by a walking action.

Despite the many technical innovations, it is important to note that the best way to ensure a smooth and safe walking experience is to follow the manufacturers instructions for correct operation, water care and maintenance of the machines. This is the only way to achieve the full benefits of this awe-inspiring machine.
