This module uses infrared light to detect the presence of black or white surfaces beneath the PASCObot. Using clever programming, students can program the PASCObot to follow (or avoid) black or white lines and/or surfaces, and much more!
The shape of the module is specific to the PASCObot, allowing the module to fit neatly inside the front of the bot, exposing the four infrared detectors on the module through the bottom of the bot body. With the included cable, students connect the module to the //control.Node allowing them the conduct sense and control experiments with the bot, of their own creation!
NOTE: The PASCObot Line Follower Module cannot be used simultaneously with the PASCObot Range Finder Module since both occupy the same slot in the PASCObot.
How It Works
This is a circuit board with four emitter-detector pairs that reflect light off the surface beneath the PASCObot to detect a black or white line. The user then can program the PASCObot to follow or avoid the line. Code can be run directly from SPARKvue or Capstone software, or uploaded to the //control.Node so guiding decisions can be made onboard the PASCObot, avoiding the communication delays over Bluetooth. However, even though the PASCObot is running autonomously, it is still possible to connect wirelessly via Bluetooth to the PASCObot to monitor data from the onboard sensors in real-time.
This circuit board mechanically fits into the PASCObot. The circuit board connects to the Control Node’s Digital Sensor Port using the included cable.
- 1x PASCObot Line Follower Module
- 1x Cable to connect the module to //control.Node
- 2x 4-40 x 7/16″ screw for mounting the module to the PASCObot body
