Step 15: V.G.E.R. With Tools
By the other hand, your students could design and install a tool for the explorer robot.
For example, your students could design, using Tinkercad, a tool controlled by a servo connected to the S2 connector
you can nd in the back side of the robot.
Below, you can see an excavator bucket design. It´s controlled by a servo and xed to the platform using two M3
hexagonal spacers and a little plastic base.
In fact, all the software you have downloaded previously, take into account the signal for this extra tool:
Joystick
Joystick. If you install a tool controlled by a servo, you have to connect it to the S2 connector. In the
software you only have to change the value of the variable "tool" to 1 and upload the program to the
micro:bit. Since then, the 'C' and 'F' button used to move the camera, will move your tool.
Explorer Robot
Explorer Robot. The program is ready to control the movement of the camera or the movement of your
tool. It will depend on the signal received from the joystick. So, you don't need to make changes in the
program, although maybe some values have to be adjusted to improve the movements of your tool.
