This set contains everything you need to build a robotic arm that can be controlled via Arduino, complete with a gripper for grasping objects and the ability to mount cameras, small solar panels, smartphones, etc.

The package includes: 6 analog RC servos with metal gears (2 type SR 311, 4 type SR 431), 1 shield for RC servos, 1 robotic gripper, the mechanical and plastic parts to make the arm structure, a wooden base with the rotation angle engraved on it, 5 volt 5 A power supply, connection cables, assembly tools and illustrated manual.

NB the shield is compatible with the following Arduino models: Uno, Uno SMD, Uno WiFi, Due, Mega 2560, Ethernet, Leonardo, Leonardo ETH, M0, M0 Pro.

Warning! Arduino is not included, see related products. For correct use of the shield, you must use IDE version 1.7.11 or higher.

• RC Servo Shield:
  – Features 12 standard 3-pin TinkerKit connectors
  – The connectors marked M1 to M6 are connected to the Arduino PWM outputs
  – The connectors marked I0 to I5 are connected to the analog inputs of Arduino
  – Each connection to the motor is protected by a fuse: M1 to M4 1.1A / M5 to M6 750 mA
  – The 4-pin connector marked TWI allows Arduino to communicate with devices that support the TWI (Two Wire Interface) or I2C ( Inter-Integrated Circuit ) interface via Arduino's Wire library.
  – The 4-pin connector marked SERIAL allows communication with devices that support serial communication. For convenience, ground and +5 volts are available directly on this connector.
  – A RESET button on the shield allows you to reset
