Adapted for STLP Camp ‘09 Mobile Robots Why do robots need to move?

Adapted for STLP Camp ‘09 What defines a robot? Sense – a robot has to take in information about its environment Plan – a robot has to use that information to make a decision Act – a robot needs moving parts to carry out commands

Adapted for STLP Camp ‘09 What ways do robots move? Rotate Convey Walk Swim Fly Reach Bend Poke Roll Snake Robot

Adapted for STLP Camp ‘09 Why go from place to place? Transport goods and materials Carry messages Get there faster Do a task while you’re getting there or when you get there Collect information about what’s there Get away from something See if you can!

Adapted for STLP Camp ‘09 How do rolling robots work? Sensors Motors Wheels Programming!

Adapted for STLP Camp ‘09 Main Components of Robotics Build – Mechanics, Mathematics, Physics Program – Building behaviors Test – Multiple trials Communicate – What did you work on or accomplish? What conclusions did you come to?

Adapted for STLP Camp ‘09 Programming Behaviors Giving the robot behaviors Complex behaviors are built from simple ones The basic behavior…is used in the simple behavior:

Adapted for STLP Camp ‘09 Programming Screen Interface Properties Area Blocks Program by dragging blocks from the menu on the left Place them on the grid, and wire them together

Adapted for STLP Camp ‘09 Testing Why do we test? Make sure it works! Understand what it can do Test everything multiple times to determine the repeatability

Adapted for STLP Camp ‘09 PAR) Personal Assistant Robot (PAR)

Adapted for STLP Camp ‘09 STLP Camp ‘Agenda’ These next 2 days we will use our PAR with sensors to program basic operations/behaviors run tests on the robot to determine its capabilities use combination of basic behaviors to create complicated behaviors Have Fun!!!!

Adapted for STLP Camp ‘09 Rules of the road Keep track of the pieces Try not to run into anyone’s robot Please return the pieces to the correct tray Take turns with programming (one on the computer, one on the robot), after each pallet, change roles Ask questions, don’t be afraid to experiment

Adapted for STLP Camp ‘09 Let’s Get Started Every team will be assigned PAR and a USB cable – check your number! Learn to program PAR to move in a variety of ways Pass a challenge Then receive whole kit to move onto sensors
