Figure Lengend Snippet: Example outputs from motors commands in the serial terminal of Arduino IDE. (a) Calibration status command before calibrating the robot. ACK: correct command; NACK: robot not calibrated. (b) Calibration command to set the initial/home position. ACK: correct command; ACK: successful calibration. (c) Calibration status command after calibrating the robot. ACK: correct command; ACK: robot is calibrated. (d) Relative movement of motor X by 100 steps and speed of 200. ACK: correct command; ACK: successful motor movement. (e) Get current position of all motors (x =100 y =0 z =0) after the movement command. ACK: correct command; successful command execution.

Figure Lengend Snippet: Incremental rotary encoder interface with Arduino (A) Schematic of the internal operation of an incremental rotary encoder which consists of two slightly shifted stationary pins (Out A and Out B) to detect voltage changes when the wheel is in motion. Right: Expected stepwise signal output from Out A and Out B pins. (B) Schematic of the two distinct signal outputs used to interpret rotational direction from the encoder. (C) Depiction of encoder bridged to wheel to track locomotion and the approximate metric to translate output from encoder to a unit of distance moved. (D) Block diagram explaining logic of interrupt-based interfacing code executed by the Arduino to count bidirectional rotations of the encoder.
