The macro plotter allows you to display a plot built from the recorded macro commands. This is very useful for exploring open loop control. You can run the T-Bot over a known route and compare the plot to the actual path taken. The rotation rate and speed factor on the slider bars are used to compensate for the real turning rate and speed of the T-Bot. The control values received by the robot are integers ranging from 100 to 300 with 300 corresponding to a maximum speed in one direction and 100 corresponding to a maximum speed in the opposite direction. The speeds are going to be effected by several factors such as trim, surface, slope, tuning, calibration etc.
Macro recording has been added to the joystick bridge controller. This provides an excellent demonstration of open loop control. You can find it here.
