When transporting the heavy loads like bridge parts ,large parts of a thermal power station or any other plants , rockets part, space shuttle where the load more than 1000 tons it becomes necessary to provide a stable platform on which the heavy load is placed & stable surface should be horizontal independent to the road surface. This stabilization is done with the help of hydraulic jacks which automatically set there position to maintain a stable & horizontal platform. Our project deals with the design & fabrication of maximum stability vehicle. The vehicle consists of 8 wheels to provide maximum stability through wheels. further stabilization is done by upper platform. It is connected to two dc motors one for each axis & one two axis accelerometer sensor. The sensor senses the tilt of platform with respect to horizontal plane in x & y direction ,now it gives this data to atmega 32 processor which process this data & generate appropriate command to drive two dc motor in such a manner that the platform remain horizontal with respect to the horizontal plane independent to the vehicle tilt on the road . Vehicle is controlled wirelessly through rf remote control. So this vehicle provide maximum stable platform through wheels ,flexible platform and accelerometer sensor. INTRODUCTION This paper demonstrates the feasibility of designing and building a self-correcting platform using inexpensive hardware and software . The platform was designed using inexpensive materials, wood and aluminum sheet metal, and was controlled by an open source microcontroller, an accelerometer, and two servos. An microcontroller, hobby grade servos, and a two-degree of freedom (axis) accelerometer were used to create the controlled platform. The intent of the platform design is to maintain the platform at an initially selected angle while the support structure orientation changes. The software was written with logic to convert the digital data from the accelerometer to an acceleration magnitude vector. The magnitude was then compared to a predetermined mathematical function to infer the angle of tilt of the platform. The angle of tilt is then converted to angle of rotation for the servos to act on. Testing showed the platform to perform as expected. Although some error on the final angle was expected, the magnitude of the error observed indicated the platform design has a high sensitivity to low tolerance mechanical joints (slop). Overall the platform design was validated based on the positional accuracy of the platform given the low quality components used to create it. In other words, the platform performed greater than the sum of its parts. The model is built up of eight wheels all making four pairs of bogie mechanism in which all eight wheels are independent and have their own driving dc- motors to give power drive. The model consist of eight 60 rpm motors to provide the wheels torque and motion and even a further up gradation is done for the platform stability so that it does not tilt and remain horizontal at any condition. The stability of the platform is managed by the use of MMA7361L ±1.5g, ±6g three axes Low-G Accelerometer Module which help to stable the platform at any instance while the robotic vehicle tilts
