Question

which of the following will increase a robots pulling power in a tug of war competition?

increasing the robots speed
placing heavy components at the top
using only sensors
using a small gear to drive a big gear

Explanation:

Step1: Analyze each option

• Increasing speed doesn't directly increase pulling power.
• Placing heavy components at the top would make the robot unstable, not increase pulling power.
• Using only sensors has no relation to pulling power.
• Using a small gear to drive a big gear (gear reduction) increases torque (pulling power).

Answer:

Using a small gear to drive a big gear.
