| Project | Approx. Build Time | Learning Outcome | |---------|--------------------|-------------------| | | 45 min | Understanding chassis dynamics & suspension geometry. | | Mini‑crane with functional winch | 60 min | Gear ratios, torque transmission, and load balancing. | | Racing drone frame | 30 min | Aerodynamics, lightweight design, and modular electronics integration. | | Customizable robot torso | 40 min | Joint articulation, modular wiring (optional). |
The 26.4 mL per stroke capacity places the 40/21 in a “sweet spot”—larger than micro-dispensers (0.5–5 mL) but smaller than drum pumps, perfect for batch processes or continuous inline production.
