Roboticarm V2 - fully 3D printable

thingiverse

This appears to be a bill of materials and documentation for a robotics project, specifically a robotic arm or manipulator. Here's a breakdown of the contents: **Bill of Materials** The bill of materials lists the components required for the project, including: * 3D printed parts * TowerPro MG995 Servos (or equal) * Ballbearing 623ZZ * Arduino ATMEGA 2560 or equal * LCD Display with I2C interface * Micro SD Card Reader for Arduino * PCA9685 PWM Driver * Mini momentary switches * Switches (ON/ON, ON/OFF/ON) * PCB prototype boards * Resistors (10 kOhm, 0.1 Ohm, 6 Ohm, 270 Ohm, 1300 Ohm) * Capacitors (ceramic and electrolytic) * Wire (stranded copper in different colors) * Bolts, nuts, and threaded rod **Description Textfile for Teaching Mode** This section describes the format of the text file used to store teaching positions for the robotic arm. The file is called `REP.TXT` or `MEM.TXT`, and it contains a series of lines with specific formatting. Each line represents a position in 3D space, with each position defined by six numbers (S000111222333444555). The first number (`S`) indicates the speed at which the arm should move to that position. The remaining five numbers represent the positions of the servos (0-5) in the range 0-180 degrees. The file format is plain text with carriage return line feed (CRLF) on each line, but not on the end of the file. This means that there will be a newline character at the end of the last line, but no CRLF sequence. **Demo Data** A sample data file `REP.TXT` is provided as an example, containing 25 lines of data that define various positions for the robotic arm. Each line represents a position in 3D space, with six numbers defining the speed and servo positions. **Acknowledgments** The document concludes with acknowledgments to individuals who have contributed to the project, specifically Alfred (for the voltage regulator circuit), Hans, and Franz (for their support).
