The serial pulse encoder pulse count is stored at each SPC and maintained by batteries found at the base of the robot.

• A. True
• B. False
• C. It is stored in cloud memory
• D. It is never stored

Answer: (A)

The key idea is data persistence for the encoder counts. The serial pulse encoder tracks movement as a running count, and keeping that tally locally on each SPC gives the system an immediate, up-to-date record of position and motion. Having a battery-backed memory at the base ensures that this count survives power interruptions. Even if main power is lost and then restored, the encoder’s tally remains intact rather than being lost or needing recalibration, which helps the robot resume correct control and maintain safe operation. Storing the count in cloud memory would add unacceptable latency and reliability risks for real-time safety-critical data, and not storing it at all would mean losing vital position information. So the described setup—storing the pulse count on each SPC with battery-backed storage at the base—is correct.
