From movies and actual facts, we often see and hear about the law enforcement forces often get seriously injured or experience death due to attempt to disable bombs. Current military technologies led to the production of bomb disposal robots, which is a robot remote controlled to detonate a bomb through varies methods in an open environment. Although this reduces the mortality rate causes by exploding bombs, but accidents often happen. Many are killed due to debris, robot malfunction, and untimely explosions. This made me question the design of the bomb disposal robots. Is this really the best way dispose of a bomb? Is there a way control the debris caused by the bomb? This robot will be very useful in the law enforcement field. The hull of the robot is in rectangular shape with a set of claw in the front. It has four Omni wheels, which allows 360 degree rotation. In the battlefield where bombs are often placed in tight environments, the robot can rotate freely and accomplish the task more efficiently. The arm attached to the claw can move in vertical motion powered by two very strong motors. This is essential as the load it carries is quite heavy. The claws attached to the arm can grab and release the load as they can rotate on a motor powered axle. Now, the claws will be carrying a big bowl, made from an alloy of lead and iron. This bowl is extremely strong and heavy, which can significantly reduce the impact of any bomb it covers. Within the bowl, there would be a small scale explosive which will be remotely activated to denote the bomb. As a part of the robotics club at AY Jackson Secondary School, our robotics team designed this robot together. We initially had several different ideas about how the structure and design of this robot. We created a matrix and evaluated each aspect of every design and chose best design. However, our school did not have budget to purchase Autodesk Inventor and the trial version could not be obtained due to our school board not recognised by Autodesk Company. We really wanted to participate in this challenge, so we used Google Sketchup Pro and AutoCAD LT instead. We first drew all the parts we needed to assemble this robot. All the parts we used were purchasable from the VEX robotics website. After all the parts were drawn, we attached all together as we were to build them in real life. Over time, all the parts slowly assembled together in a logical manner. After the design was done, we purchased all the actual materials and created a life size prototype of this robot. It was successful other than the fact that stronger motors are needed to lift a real bowl and a real bowl with lead and iron needs to be developed. The most useful tool was grouping varies parts together, It allow easy copying and moving of the object in the drawing. ................
