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.
Change to actual motor OOPS. Needed to change to backwards, because of location of bumper
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.
