1.
Type of wheel when designing a robot is irrelevant for the rear axle. However, the front wheels should be lightweight.
Correct Answer
B. False
Explanation
The given statement suggests that the type of wheel used for the rear axle of a robot is not important, implying that any type of wheel can be used. However, it states that the front wheels should be lightweight. This means that the type of wheel used for the front wheels does matter and should be lightweight. Therefore, the correct answer is false, indicating that the type of wheel used for the rear axle is not irrelevant.
2.
By looking at the gear arrangement of this robot, you can tell that it is designed to
Correct Answer
C. Climb a steep incline
Explanation
The gear arrangement of a robot is crucial in determining its functionality and capabilities. In this case, the fact that the robot is designed with a specific gear arrangement suggests that it is intended to climb a steep incline. The gears are likely designed to provide the necessary torque and power to overcome the challenges posed by steep inclines, allowing the robot to navigate such terrain effectively. Therefore, the correct answer is "Climb a steep incline."
3.
To get maximum power at low speed, you need to have
Correct Answer
C. A large gear on the wheel axle and a small gear on the motor
Explanation
To get maximum power at low speed, it is necessary to have a large gear on the wheel axle and a small gear on the motor. This is because a larger gear on the wheel axle allows for more torque to be transferred to the wheels, resulting in greater power. On the other hand, a smaller gear on the motor allows for higher rotational speed, which is not necessary for low speed applications but can help in achieving maximum power. Therefore, the combination of a large gear on the wheel axle and a small gear on the motor is the most suitable for maximizing power at low speed.
4.
To achieve a higher speed, you need to have
Correct Answer
A. A large gear on the motor and a smaller gear on the wheel axle
Explanation
To achieve a higher speed, you need to have a large gear on the motor and a smaller gear on the wheel axle. This is because the gear ratio determines the speed and torque of the system. When the motor's large gear drives the smaller gear on the wheel axle, it results in a higher speed but lower torque. The larger gear on the motor allows for more rotations per minute (RPM), which translates to a higher speed. Meanwhile, the smaller gear on the wheel axle reduces the rotational speed but increases the torque, allowing the system to maintain power while achieving a higher speed.

To stop a hill climbing robot from flipping when climbing a steep incline, the following idea has the greatest chance of helping
Correct Answer
C. Placing weight forward of centre
Explanation
Placing weight forward of center would help prevent the hill climbing robot from flipping when climbing a steep incline. By shifting the weight towards the front, the robot will have more stability and better traction on the incline. This will prevent the robot from tipping over backwards and maintain its balance while climbing.
6.
It is important for which type of robot to be lightweight.
Correct Answer
C. Sprintbot
Explanation
Sprintbots need to be lightweight because their main function is to move quickly and cover distances in a short amount of time. Being lightweight allows them to have faster acceleration and higher speeds, which are essential for their purpose. Additionally, a lighter weight helps to reduce energy consumption and strain on the robot's components, enabling them to perform optimally during sprints.
7.
In which kind of robot is the weight of most advantage?
Correct Answer
C. Tug-Of-Warbot
Explanation
A Tug-Of-Warbot is a type of robot that is specifically designed for pulling heavy loads in a competition. In this context, the weight of the robot is advantageous because it provides more traction and stability, allowing it to exert greater force and win the tug-of-war. The heavier the robot, the more difficult it is for the opposing team to pull it across the line, making it more advantageous in this particular type of competition.
8.
A robot that is able to make decisions with its own intelligence.
Correct Answer
B. Autonomous
Explanation
The correct answer is "autonomous" because it accurately describes a robot that is able to make decisions with its own intelligence. This means that the robot is capable of operating independently and does not require constant human control or input. The term "autonomous" implies that the robot has the ability to perceive its environment, process information, and make decisions based on its own internal programming and algorithms.
9.
Converting a measurable physical quantity into a usable electronic signal.
Correct Answer
C. Sensing
Explanation
The process described in the question involves converting a measurable physical quantity into a usable electronic signal. This aligns with the concept of sensing, as sensing refers to the ability to detect or measure physical quantities and convert them into a form that can be understood or utilized. Therefore, sensing is the correct answer in this context.
10.
The "brain" of the robot is the
Correct Answer
A. Controller
Explanation
The "brain" of the robot refers to the central processing unit that controls and coordinates the robot's actions. It receives information from input sensors, processes it, and sends signals to the actuators to perform the desired tasks. The controller is responsible for making decisions based on the input received and executing the appropriate actions. Therefore, the controller is the correct answer as it acts as the brain of the robot.
