Atlas Robot Arm (1980s) Upgraded with Arduino – Educational Robot

Price: £500

Location: Bristol, UK – Collection only

Product Description

This Atlas robot arm from the 1980s has been modernized to incorporate an Arduino controller, offering enhanced flexibility and programmability for educational, hobbyist, or practical applications. Suitable for various projects, from simple movements to complex automation tasks, this robot arm is an excellent tool for learning and experimentation.

Features

• Power Supply Recommendations: Recommended to use a 24V DC bench-style power supply. The arm includes a buck converter with inductor smoothing to minimize power ripple, enhancing Arduino performance.

• Motor Control: Control each motor by sending specific bytes via a serial terminal:

  • 'A': BasePanStepper

  • 'B': TiltBodyStepper

  • 'C': ClawTiltStepper

  • 'D': ClawGripStepper

  • 'E': ExtensionStepper

  • 'F': ClawRotateStepper

  • 'Z': Activates a demo mode

• Safety Features: Current limiter set at about 1.5A, standard fuse size at 2A (recommend upgrading to 3A if using holding torque extensively).

Usage Guide

1. Setup: Open your Arduino IDE or preferred serial terminal. Connect to the Arduino Mega via the designated COM port.

2. Operation: Send a byte specifying the motor, followed by the numerical position (e.g., 'A6000' moves the pan to position 6000,). Note that positions should not exceed the motor range limits as the arm does not have end stops.

Project Ideas

• Educational Tools: Design tasks like simulating a nuclear reactor arm or setting up a mock production line using Lego or 3D-printed parts.

• Interactive Games: Program the robot to perform tasks like picking up objects with precision, incorporating scoring systems for added challenge.

• Innovation: Enhance the robot's capabilities by adding sensors (e.g., IR, sonar, force sensors), integrating I2C or SPI devices like LCD displays or dot matrix for expressions, or implementing voice commands via modules compatible with Amazon Alexa.

• Remote Operation: Develop mobile applications for control or set up a web server on a Raspberry Pi to manage the robot arm through web browsers.
