DISCUSSION
Since the last 3 months ago, we have mission to produce a functional autonomous robot for serving water or food during either meeting or convention session for our Mechatronics System Design. For that reason, we have equipped the robot with intelligence system and embedded with flexible function during its operation.
Since we have limited budget and equipments, most of the materials that are used for this project from recycle materials that can be found in MSD lab, Robocon lab and Mechatronics workshop. The design of prototype needs lots of modification compared to the alternatives design that we have chosen before due to the problem that we faced to find the exact materials for this prototype concept. Thus, from that, our finalized budget for this project less than RM 50 because many materials are from recycle things. The final prototype design as shown below.
PROTOTYPE PRODUCTHowever, we have successful created the food container which the foods or beverages will be brought by robot and the customer just push the button to make it throw out the food from the box. The box is created by plank and we design it well in order the food can go out from container easily.
The single slotted track we have created it from aluminium element because of easy to figure it as same as the shape we want to create such as for corner side (round shape). So, the tyres of the robot run and follow very well in the slotted track. It can rotate the table smoothly by following the track depend on suitable speed that mean not much faster or too slow.
CONCLUSION
Our objective of this experiment has been achieved although it doesn’t function well during presentation. Based on our knowledge learned in the Mechatronics degree programme, our ideas to improve the project is always in our mind. This project is an introduction to the world of robot that aids our daily life. Hence, with this robot there is safety for confidential meeting and also it can save companies money from using in unnecessary things.
