Abstract—The objective of this robot is to move over even surface and to climb stairs. The uses of this robot are transportation of goods, rescue purpose and to reduce the labour work. In this we use planetary wheel arrangement to drive the wheels which helps to move the robot in even surface. And a shaft arrangement to rotate the wheel while climbing the stairs. The technical issue in designing the robot is stability and speed of robot while climbing steps Keywords—Wall Climbing Robot, Planetary Wheel, Stair Climbing. I. INTRODUCTION The project introduces a new horizon for the transportation of the loads over the stair. Most of the buildings of the country are structurally congested and unavailing of elevator facility so it is difficult and laborious to lift up heavy loads. The stair climbing vehicle can play an important role in those areas to lift loads over a …show more content…
The vehicle is designed in such a way that it can climb a stepped path (like stairs) with its modified wheel structure. Not only on the stairs, can it also move with load over flat or rocky surface. This is the individuality of this …show more content…
The planetary wheel was connected with the sun wheel through an idler. The purpose of using the idler was to rotate the planetary wheels in the same direction of sun wheel. Each planetary wheel was aligned in a straight line with idler and sun wheel. Planetary wheels were 120° apart from each other (figure 1). The tapered idler was also planed to disengage the planetary wheel from the sun wheel, while it was not used to save power. However, the idlers generate frictional force, which requires more powerful motor. Slip might occur if adequate friction is not available. So finally an especial type gear arrangement have been designed which is more stable and consume less power (figure

Toyota Sienna comes with “in-floor” system that VMI is known for. In opposed to "fold-out"-style ramp, the in-floor unit is placed between the passenger floor and the bottom of the vehicle. The main advantage of an in-floor ramp is that it doesn't intrude into the passenger area of the van when stowed, which leaves more room for ...

The basic components of today's mobility scooters are two rear wheels with a seat above them, a flat area upon which to put the feet that also holds the seat and power source, and a steering column with handlebars to steer either one or two front wheels. There are gasoline powered ones, though
People have long used truck-like vehicles to transport goods, but as societies have changed, the need for better, more powerful ways of transportation has grown alongside the development of society. Improved vehicles require better means of movement, just as improved roads and movement among places has allowed for the development of better vehicles. The trucks of today fulfill many job descriptions, but their usage is solidly defined in the human consciousness: a truck is not mistaken for any other type of vehicle. From its early use as “a cart for carrying heavy loads” to the modern “motor vehicle for carrying heavy loads,” the word
the length of the slope can be used to calculate the speed of the car
Hydraulic lifts: offered minimum comfort, low speed, lmited travel height, low cost (<50% of geared lifts). Needs huge amounts of oil and is potenital fire and safety
Before the advent of the automobile, buggies were typically propelled by one or more horses. Even with the first automobiles there was a need for a drive system, though, since those horses were no longer there. One thing that has remained common to every car is a motor and transmission system of some sort, but what varies greatly between cars is what is between the transmission and the wheels, also known as the drive train. There are many different styles of drive trains, each with their own advantages and disadvantages.
The important thing to know about an object that is moving on wheels is that its kinetic energy is equal to half of its mass including the wheels(Mb) multiplied by the square of its velocity(V) plus the kinetic energy in the rotating wheels. In this case I am going to assume that all of the mass of the wheels is located on the outer edge (this isn't really the case, but most of the mass is there). Then the kinetic energy of a wheel due to rotation is half of its mass(Mw) multiplied by the square of its radius(r) multiplied by the square of its angular velocity(w) multiplied by two since there are two wheels.
This essay will show how common the robot will become within the next decade. It also shows how far computer technology

To learn and experience something new and out of your norm can be a pretty scary thing, almost like being in a foreign country and not knowing your surroundings; what do you do? You panic! I can remember clearly an event during my childhood, it was one of the hardest thing I've ever had to do, and that was learning how to rock climb. All my friend’s parents would take them to a nearby gym after school. It was a gym for kids and rock climbing was the cool thing to do. I wanted to go so badly and feel cool, just like my friends, but I was always afraid of heights. Never liked heights as a child, and when I was growing up I was left with that fear. One day I decided to face my fears, and thought to myself that rock climbing was an important skill to have under my belt. Also I thought this was a step closer to overcome my fear and rock climbing was the perfect way to get over that fear. I also knew this would be a great experience and will help me become physically and mentally stronger. What I didn’t realize was that learning to rock climb would also boost my self-esteem and to make me believe in myself more. I always felt on edge when I was faced with a new situation. It made me feel uncomfortable and not quite myself, it still does sometimes. But I knew with my very first rock climbing lesson there weren’t any more excuses! I simply had to face my fear and just do it. There was no going back.

In Japan, they created humanoid robots that are able perform regular human tasks, including driving. “A Japanese research consortium demonstrates a humanoid robot driving a backhoe” (Nocks).
