Robotics

Lab: (Finish parking). Bluetooth applications

Homework: Postings. Next class: Library research project presentations!

Bluetooth example

• Master robot moves until bumper. Sends rotation sensor value.

• Slave waits for message: displays value.

• Note: one or the other robot needs to convert number to text

• Need to start the waiting robot first.

OOPS. Needed to change to backwards, because of location of bumper

Change to actual motor

Note

• Good use of comments– Indicate name of other program– Indicate starting information– ?

Suggestions

• Try this or something no more complex before moving to something more substantial.

• May need to record, or say to each other,– which is master/which is slave– which one starts first

• May need to insert displays or sounds to confirm what is happening

Challenge

• Work in multi-robot teams

• Use grabber

• Find and distinguish red or blue ball– Use MyBlock and global variables

• Send Bluetooth message to appropriate slave/helper/??? NXT

Homework• Library project on APPROVED topic

• Prepare 1 page: summary, image, bibliography (at least 3 sources. Give complete citations)

• Formal presentation– PowerPoint charts or other format (e.g.,

HTML, prezi, Google presentation)– Content: as appropriate, integrate information

from sources and give your own reasoned opinion. Ask question(s) of class.
