updated this to reflect actual geometry of the arm. Has variable out of x,y,z position of jaw and optionally the points of interest (r,z) of each arm segment. POI is used for illustrating position of arm.
changed output to variable output
function to plot the side view of the arm w/ circles to indicate joints and a red square to mark the jaw
this function creates a 3D plot of the arms current position.
preliminary code to map arm position. was replaced by plotArm2D.m
updated to use actual geometry of arm. still needs some fixing
plots/animates the moves of the movement of the arm as each joint sweeps from 0 to 90 degrees
test that connection to serial is working properly
plots jaw position and angles of each joint as joints sweep from 0 to 90 degrees, on at a time.
