• Identify the task you want your robot to solve.• How will you use all 9 core technologies?• Quiz tomorrow on the following:

• Be able to list the 9 core technologies• You will be given technological artifacts and be

required to identify which core technology corresponds to which artifact and explain.

• You will also need to be able to sketch a diagram that shows the transfer of energy in an electric car and a gas-powered car.
