The need to develop a highly stable suspension system capable of operating in
multi terrain surfaces while keeping all the wheels in contact with the ground. To
design a mechanism that can traverse terrains where the left and right rockers
individually climb different obstacles. To sustain a tilt of over 50degree without
tipping over the sideways .Rocker bogie are important for conducting scientific
analysis of objectives that are separated by many meters to tens of kilometers. Current
mobility designs are complex, using many wheels or legs. They are open to
mechanical failure caused by the harsh environment on Mars. A six wheeled rover
capable of traversing rough terrain using an efficient high degree of mobility
suspension system. Six motors are located inside the body where thermal variation is
kept to a minimum, increasing reliability and efficiency. Six wheels are used because
there are few obstacles on natural terrain that require both front wheels of the rover
to climb simultaneously. A series of mobility experiments in the agriculture land,
rough roads, inclined, stairs and obstacles surfaces concluded that rocker bogie can
achieve some distance traverses on field.

SMART gas trolley with wheels is an initiative to improve the existent trolley that is being used to deliver gas tank. An improved gas trolley is designed and developed mainly for stair climbing with a total cost of M339. Three types of fabrication processes are involved to fabricate the gas trolley : welding, machining and finishing. The completed trolley was tested at stairs with load and without load. The result shows that the gas trolley required an average 27.7secondss with load to climb up the stairs and 23.5secondss to climb down the stairs. On the other hand, the trolley required only 13.8secondss to climb up the stairs and 0.73secondss to climb down the stairs. Hence it can be concluded that the gas trolley needs less than 1minute to deliver the load by climbing up and down of the stairs. In brief, this innovation is expected to contribute to polytechnic educational system academically and practically.
