: Uses an ultrasonic sensor (like the HC-SR04) to detect objects and steer around them.
: Uses ultrasonic range finders to maintain a specific distance from walls while moving. Arduino Robotics
: Typically powered by an Arduino Mega due to its high number of I/O pins, which are needed to control multiple servo motors for joint movements. : Uses an ultrasonic sensor (like the HC-SR04)
: Utilizes infrared (IR) sensors to track and follow a black line on a white surface. Arduino Robotics
: Can be driven via WiFi or Bluetooth using modules like the HC-05 or boards with built-in connectivity. Essential Components Simple Arduino Robotics Platform! : 5 Steps - Instructables
