Explanation:

Question 2

A line tracker (in robotics, e.g., VEX) is a digital sensor as it outputs discrete (digital) signals (like on/off or binary values) to detect lines. So the statement is True.

A line tracker detects objects/lines (using light reflection, e.g., detecting black/white lines). Radar detects objects by sending/receiving signals (similar principle of detecting via reflection). URF (ultrasonic range finder) measures distance, UFO is unrelated, GPS is for location. So line tracker is similar to Radar.

Answer:

True
