Unlock New Dimensions: Building Robot Arms with Excel

I enjoy seeing how far you can take Excel.

This is a playable workbook that models 2D and 3D robot arms using only ordinary spreadsheet formulas, charts, sliders, and Solver. You can move the arm with red input cells or sliders, set a target point, and then use Excel’s Solver Add-in to find the control values that move the hand to the target.
