control 3 DOF robot arm using mouse, thought Processing
Also read https://sites.google.com/site/arduinorobotprocessing/home/arduino/2-arduino-x-robot/2-7-robot-arms to learn the theory and the connection
the define servo angles are 90, using a servo tester, set the angle to 90, see if the robot align the dh graph above if not, find the inputing angle that the real robot arm angles are 90 degree
Open the Processing code, find the above array
the perimeter are min. angle, standard angle(90), max. angle and direction respectively.
for the direction, 0 means your servo direction is same as the dh graph, 1 means it is oppositive to the direction shown in the dh graph
###UPDATE 2018-03-10 ROBOT from 4 DOF change to 3 DOF, a uArm link robot A complete GUI is intergated with the servo testing function
