This series of three pound combat robots feature field swappable weapon attachments. This allows matching the weapon type to the opponent.

| Dinner Time with its three attachments. |
Dinner Time was the first modular robot I made, with three different attachments. There was an undercutter, for use against drum types, certain types of wedges, and overhead bars. A vertical spinner is used for most wedge type robots, including vertical spinning weapons with feeder wedge. Finally, an elevated horizontal spinner (over-undercutter) is used against mid-cutters and undercutters. This robot competed in Motorama 2017, winning first place.

| Margin of Safety 4 with vertical spinner. |
For continuity the Margin of Safety name was restored. This one features a full 3D printed frame and connectorized attachments. Modules could be swapped in 30 seconds, allowing races with other modular robots on who gets the weapon type advantage. The over-undercutter attachment was put on hold due to weight issues. This one won Dragoncon 2017 and Dragoncon's Tea Cup Racers.
