Read full description

For use with the engineering kits “Robotics: Smart Machines”, “Robotics: Smart Machines - Rovers & Vehicles Edition”, and “Robotics: Smart Machines - Tracks & Treads Edition” by Thames & Kosmos. This app is the “brain” of the robotic models you build with the Robotics: Smart Machines kits. The app uses the feedback from the models’ ultrasonic sensor together with programmed commands to control the models. App Features • Connect to your models via Bluetooth connection. • Remote-control mode lets you directly control the models’ two motors forward and backward. • Remote-control mode gives you a visual display of the object distance readings from the ultrasound sensor. • Programming mode lets you script and save programs. • Seven programs (Programs 1-7) are preloaded to work specifically with seven of the robot models in the “Robotics: Smart Machines” kit. Eight programs (Programs 9-16) are preloaded to work specifically with eight of the robot models in the “Robotics: Smart Machines - Rovers & Vehicles Edition” kit. Eight programs (Programs 17-24) are preloaded to work specifically with eight of the robot models in the “Robotics: Smart Machines - Tracks & Treads Edition” kit. • A simple, visual programming language lets you program motors, sounds, and pauses. • Different program segments can be set to run upon first run and then when the ultrasound sensor detects objects at different distances from the model. • Use the 60-page or 64-page, step-by-step illustrated manual included in either kit to learn how to use all of the programming features. ***** Suggestions, feature requests, or questions?
