Trepidation can be understood as any movement that moves, that oscillates. The Shake Robot is nothing more than a robot that trembles, thus managing to move.
With the construction of the Shake Robot, the student can understand, in a practical way, how the shaking works. Facilitating learning in Physical.
The 5v DC motor, connected to a 9v construction battery with a weight similar to that of a glass arm, is connected to a box-like structure. You can use pens like “legs”, or any cylindrical shape for the robot to move.
