Robot arm kinematics in Excel cells — no code, just formulas and Solver.

Strengths
  • Every calculation visible in spreadsheet cells — nothing hidden in black-box libraries
  • 3D version models real Armatron toy with 3x3 orientation matrices in formulas
  • Excel Solver finds inverse kinematics solutions without custom optimization code
Weaknesses
  • Desktop Excel only — no web or mobile support limits accessibility
  • Niche educational use case won't replace actual robotics simulation tools
