Labour for climbing coconut trees is getting scarce. Attempts were carried out to replace the man with a robot. But they failed due to many reasons .So there is a need to come up with a safe and effective coconut tree climbing device which is capable of elevating a human along the tree trunk.

There had been several other attempts locally & internationally to come up with devices which are capable of elevating a human along the trunk & also coming up with tools which make the task of the man climbing the tree safer. But they lack certain important aspects as well. Hence we took the task of coming up with a more effective & safer device which can elevate a human along a coconut tree.

Underwater exploration is a major research area around the world and people have understood its importance as much as space exploration. Many universities and oceanographic institutes around the world are carrying out research and development projects on underwater exploration vessels (UEV), but not a single Sri Lankan university / institute in the list. To full fill this void and to introduce a completely new research area to the university, a group of final year students started this project as their final year research project a year ago. This is an extension of the last year UEV (Under Water Exploration) project aimed at overcoming the drawbacks of the previous vessel.

Production of coir dust briquettes for export is a rapidly growing industry in Sri Lanka today. Coir dust briquettes are used for horticulture purposes in the western countries. The export of coirdust briquettes which is a relatively new business in Sri Lanka is also extremely profitable. As a consequence more and more industrial organizations are entering the field of coir dust briquette manufacture. Thus, the demand for coir dust briquette manufacturing machines and the price of coir dust in the local market has increased. Most of these machines designed to produce coir dust briquettes are operated manually. In order to meet the rising demand for these briquettes, industrialists prefer to operate these machines round the clock. In addition, automation would increase the productivity of the machine while reducing the labourcost. We believe that there is a significant d

When considering alternative energy sources for a single passenger vehicle, the most available form is direct power given by human effort. This energy is most frequently utilized in two wheeled bicycles. However bicycles have certain drawbacks such as, exposure to weather & sunlight, less carriage capacity, low efficiency of power train, limited millage and most importantly less stability of the vehicle thus poor safety of the rider. Three wheeled vehicles though they are much stable than bicycles, also have few of the downfalls stated above. The friction of tires is a main fact that has to be considered when designing vehicles. Two wheeled vehicles are much efficient compared to three wheeled or four wheeled vehicles. Considering most of the facts stated above a novel concept of two wheeled vehicle with two support wheels have been designed, built and tested for suitability of satisfying the above given problem.

Advances in automating manufacturing processes have been driven by several competitive forces, such as continual need to improve productivity and product quality and to decrease manufacturing costs. Some of the leading refrigerator manufacturers are planning to increase their production rates. The cabinet of the refrigerator is fabricated in a single production line starting with a sheet metal.
