Castle Crasher - Lesson 4 - Optical Sensor

Hey all,

Making my first run teaching a robotics course, having a great time. The students and I finished up the Sense and Sweep challenge by coding the robot to utilize the distance sensor.

We’re moving on to Lesson 4: Creating Algorithms, and the lesson materials have you mounting the optical sensor near the distance sensor with some 90 degree brackets. I went ahead and did that, but the buckyball does not fit under the sensor to be detected when mounted this way. Is the intent to have students design a better way to mount the sensor, or am I missing something about how to correctly use this sensor?

The videos that follow in the lesson materials demonstrate how to use the sensor, but I see it is mounted in place of the distance sensor, facing forward.

Any help would be appreciated, thanks!

Hey David,

Can you send pictures of how you mounted the optical sensor? Please also include a buckyball under the sensor. So we can take a look to see what may happened.

Additionally as a PD+ all access user, you can book a 1-on-1 session with us. So we can help you out in a video call.
