This page shows all the robotics tutorials listed without specific grouping. Each tutorial is short, on specific topic, has a video. Tutorials are structured in sequence in Courses.
Sites are outlined on the mat wireframe.
Factories use large amounts of energy to make the products we use such as toys.
Deliver energy units to the toy factory bin and release the mini dinosaur toy.
Water from the river above the dam is stored in the reservoir. Water from lower down the river can also be pumped back up to fill the reservoir at times when there is excess electricity to use.
Place the looped water units from the river above and below the dam into the water reservoir or onto the red hooks.
New technologies help us to store energy. Volcanic rocks can be heated in an insulated enclosure to store energy until it is needed.
Load energy units into the energy storage bin and then release the stored energy unit from the tray under the model.
This is a 10 out of 10 video tutorial that is different from the rest. We demonstrate how difficult it is to accomplish a mission and we use an attachment that is working 5 out of 10 times. Our goal with the video is to give everybody the understanding that taking your time to accomplish a mission is the right thing. Most of the 10 out of 10 tutorials at FLLCasts contain solutions and approaches that are working in a repeatable fashion. Not this one. See how difficult it is to accomplish a mission and that we also make mistakes.
Having a package delivered to your doorstep is awesome! Packages can be transported safely, on time, and to your door.
