1. My first robot programming - Simple “Go” Young Joon Kim http://www.helloapps.com MSRDS First Beginner Course – STEP4

2. 2 Topics Preparing basic environment Simple “Go” drive “Go Forwards” drive “Go Backwards” drive Stopping a robot Going around Turning round

3. 3 “Go” Drive Commands

4. 4 Go –Drive a robot with motor power –Motor power is set with given value and keeps its value Usages –robotname.Go() //default power is 0.2 –robotname.Go(power) –robotname.Go(left_power, right_power) Range of motor power values –-1.0 (Max backwards) ~ 1.0 (Max forwards) –0: Stop the motor

5. 5 “Go” Drive Commands Go forwards –Use the value above 0 –Ex) robotname.Go() robotname.Go(0.3) robotname.Go(0.2, 0.2) Go backwards –Use the negative value –Ex) robotname.Go(-0.3) robotname.Go(-0.2, -0.2)

6. 6 “Go” Drive Commands Stopping a robot –Use the value 0 –Ex) robotname.Go(0) robotname.Go(0, 0) robotname.Stop()
