The Robotics Lab Cable
Four student robots—Atlas, Beep, Coda, and Dot—use four numbered charging bays. One bay has the only high-capacity cable needed by Atlas. After the bay labels are moved during cleaning, the team reconstructs the arrangement.
Your task
Which bay has the high-capacity cable?
- 1
Dot charges in Bay 4.
- 2
Coda charges immediately to the left of Dot.
- 3
Beep charges in Bay 1.
- 4
The high-capacity cable is in Atlas’s bay.
Solution revealed
Solution
The answer: Bay 2
Dot occupies Bay 4, so Coda must be immediately left in Bay 3. Beep is assigned Bay 1. This leaves Bay 2 for Atlas, and the high-capacity cable is explicitly in Atlas’s bay. Therefore the cable is in Bay 2.

Why this answer is the only fit
Bay 2 is correct.
Dot occupies Bay 4, so Coda must be immediately left in Bay 3. Beep is assigned Bay 1. This leaves Bay 2 for Atlas, and the high-capacity cable is explicitly in Atlas’s bay. Therefore the cable is in Bay 2.
