The decoration of the robot so that it looks like a bat aims to give enough time to the slower building teams to catch up. Wait for the moment, when all of the teams have worked on the decoration for at least 5 minutes and then introduce to all of them the new theory. The tasks are not that clear about what should happen. This is so in order to keep the story behind the lesson. You will need to clarify the tasks where needed. Just try not to go in details such as exactly how many degrees or centimeters. Left the students to figure out the values on their own.
Example solution to the taskĀ "Bat stays hidden and waits for its prey before attacking"
Example solution to the taskĀ "The bat is moving forward until it detects an obstacle and stops"
Example solution to the task "The bat avoids an obstacle by turning to the side and stops at the next obstacle"
Example solution to the task "Hunter - the robot spins in place until it detects prey. Then it attacks forward"
Example solution to the task "Program the bat to wait till his prey gets close and then attack. Program it to continue his attack till it bites his prey with his touch sensor."
Example solution to the task "Program the bat to move till it bites something with his touch sensor and then to turn around and go hunting again."

Robotics with LEGO - Level 1.0 - Adventure in Space
The first level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.
Various constructions with robots are built. Learn how to control the motors so that the robot navigates around the Moon and Earth in various ways. Getting to know the first two sensors. The robot can feel its surroundings with the help of the Touch sensor and avoid obstacles.
The Ultrasonic distance sensor can help the robot avoid obstacles. Students work with concepts like loop, degrees and medium motor. Robots can now do two different actions at the same time - while solving missions on a field, the third motor clears detected obstacles.
