  1. Transform the Design of Our RobotFill in names below: Names: Tabitha, Lim Zi Yi and Lau Liang Hong Class: 5N

  2. Problem Scenario The transformers destroyers from Mars have landed on Earth to challenge our transformers robots to a race. The fate of Earth depends on your design of the racing robot. Suggest ways of improving the model of the robot shown to you by your teacher so that you can win the race. Put your suggestions in the third slide of the template. For each suggestion, fill in the types of energy used in the fourth slide of the template. Do a research on the Internet for 6 of the methods you suggest and put your finding on 6 different slides which you can add to the template.

  5. 1. How to improve the vehicle? Suggestions: • Use a big gear to drive a small gear • Use wheel and axle • Reduce air resistance by making it streamlined • Reduce mass by changing the materials • Add a sail to it • Add a propeller • Add a rocket engine • Use wheels instead of caterpillar tracks • Add solar panels • Add a steam engine

  6. 2. Types of energy used

  7. 3. Research on 6 methods suggested 1st: Gears Gears can change the direction of motion and give us the mechanical advantage to do work. A worm and gear Big and small gears Helical gears Rack and pinion animation Internal gear

  8. 3. Research on 6 methods suggested 2nd: Sail A sail is any type of surface intended to generate thrust by being placed in a wind — in essence a vertically-oriented wing. Sails are used in sailing. Sails are primarily used at sea, on sailing ships as a propulsion system. 3 For purposes of commerce, sails have been greatly superseded by other forms of propulsion, such as the internal combustion engine. For recreation, however, sailing vessels remain popular.

  9. 3. Research on 6 methods suggested 3rd: Propeller A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of a vehicle such as an aircraft, ship, or submarine through a fluid such as water or air, by rotating two or more twisted blades about a central shaft, in a manner analogous to rotating a screw through a solid. The blades of a propeller act as rotating wings (the blades of a propeller are in fact wings or airfoils), and produce force through application of both Bernoulli's principle and Newton's third law, generating a difference in pressure between the forward and rear surfaces of the airfoil-shaped blades and by accelerating a mass of air rearward.

  10. 3. Research on 6 methods suggested 4th: Fuel cell A fuel cell is an electrochemical energy conversion device. It produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte. Generally, the reactants flow in and reaction products flow out while the electrolyte remains in the cell. Fuel cells can operate virtually continuously as long as the necessary flows are maintained.

  11. 3. Research on 6 methods suggested 5th: Solar panel A fuel cell is an electrochemical energy conversion device. It produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte. Generally, the reactants flow in and reaction products flow out while the electrolyte remains in the cell. Fuel cells can operate virtually continuously as long as the necessary flows are maintained. Solar cell Solar cars

  12. 3. Research on 6 methods suggested 6th: Steam engine A steam engine is an external combustionheat engine that makes use of the heat energy that exists in steam, converting it to mechanical work. Steam engines were used as the prime mover in pumping stations, locomotives, steam ships, traction engines, steam lorries and other road vehicles. They were essential to the Industrial Revolution and saw widespread commercial use driving machinery in factories and mills, although most have since been superseded by internal combustion engines and electric motors.
