Robot Arm

Compact Robot Arm

• Base Structure: The robot arm consists of a base with several joints and segments, allowing it to articulate and move in multiple directions.

Servos:

• High Torque Servo Motor: Provides the primary movement strength for the main joints.
• Standard Servo Motors (3): Control additional joints, enabling precise movements.
• Micro Servo: Operates the gripper mechanism for picking up objects.

Controller

• Arduino Uno: The central microcontroller used to program and control the robot arm's movements.
• Servo Driver Module: Manages and coordinates the actions of the multiple servos.
• Potentiometers (4): Allow for manual adjustments and control over the servo positions, providing fine-tuned control of the arm.
• Push Button: Additional control input for triggering specific actions or modes.
• Power Supply: A 7V power supply provides the necessary electrical power for the servos and controller.
• Wiring and Connectors: Various wires and connectors used to link all electrical components, ensuring proper communication and power distribution.

Features and Capabilities

• Articulated Movement: The arm can move in multiple directions due to the strategically placed servos, allowing for complex maneuvers and positioning.
• Gripper Functionality: The end-effector or gripper can pick up and manipulate objects, making the arm useful for a variety of tasks.
• Programmable: Using the Arduino platform, the robot arm can be programmed to perform automated sequences or respond to manual controls.
• Customizable: The 3D printed parts and modular design allow for modifications and upgrades, such as adding different end-effectors or improving structural components.
