All tasks below are fully automatic. This program displays all the robot points for 6 servos on a web page. Using buttons on the web page you can adjust them, jog between points and then save them to EEPROM/flash when done. Otherwise all 90 angles are lost on power off unless put in the program. Program includes a speed control function to slow down the full speed, jerky motion you get directly going between points. On boot up it reads the initial point from EEPROM and goes to it rather than jerk to the default 50% servo travel. Start/idle position is where the robot falls to on power off. Industrial robots have brakes on all axes so they never fall on power off. Program includes 3 lines for wireless uploads.
