| Underwater Robotics |
| Underwater Robotics with LEGOs |
| Motors, wires, and all traditional pieces work in water | ||
| RCX and sensors do NOT work in water | ||
| Additional materials | ||
| Propellers (www.hobby-lobby.com or www.towerhobbies.com) | ||
| Foam (or some sort of floatation aid) | ||
| RCX case (www.microelectronics.com) and Aquaseal | ||
| Underwater curriculum |
| Possible areas of focus | |
| Robotics | |
| Water quality and testing | |
| Ecosystem exploration (MBARI) | |
| Slide 6 |
| Underwater Robotics Activities |
| Activities |
| Activity outline | |||
| Boat that floats (buoyancy and density) | |||
| Have a BalLAST (neutral buoyancy, density, and ballasts) | |||
| Prop-line (propulsion, drag, and friction) - | |||
| Prop-line contŐd (gears) | |||
| Dizzy boat (torque) | |||
| Building project (choose one or both) | |||
| Slalom boat (engineering) | |||
| ROV (engineering) | |||
| Boat that floats |
| Introduce building with LEGOs | ||
| Concepts of: | ||
| Buoyancy | ||
| Density | ||
| Stability | ||
| Misconceptions of what does/doesnŐt float | ||
| LEGO floats initially because air gets trapped in crevaces | ||
| Boat that floats |
| Have BalLAST |
| Construct a neutrally buoyant submersible | ||
| Dive and resurface | ||
| Remain at constant depth | ||
| Concepts | ||
| Buoyancy | ||
| Density | ||
| Air compression | ||
| Pneumatics | ||
| Prop-line: Part 1 propulsion and drag |
| Build device to test different sized propellers | ||
| Concepts | ||
| Propulsion | ||
| Drag | ||
