Robotc pid control update#

Please be sure to update your brick to the latest Linux firmware. New Linux image, updated to 1.07X to ensure compatibility with LEGO EV3 Programming Software.Bug causing Graphical Block artefacts on the screen has been fixed.Hitting the Control key no longer deselects all the things.Fixed a bug where the missing “Name” field would cause a crash for the command line activation.Fix issue that prevented functions that return pointers to be dereferenced in an expression.Fix bug in addTo/MinusTo/DivideTo/TimesTo opcode when variable is a global short variable and the operand is a 16-bit or less compile time constant.Long operands on opcodes “&” “|”, “^” and “~” were incorrectly handling negative 16-bit constants.

IDE was not removing error flags from graphical blocks.Fix issue with command line deactivation with building licenses.Fix the repeatUntil(0) warning message to say “‘repeat until’ expression is constant ‘0’.Context menu for large ICON toolbar changes now take immediate effect.

Fix issue where a “save as” with a new document -> then a subsequent “save” would cause a “save as” prompt in the wrong location.

All libraries (DLLs) and executables are now signed.

CTRL+ALT+SHIFT+D” is new keyboard accelerator to open preferences.

This will allow it be be either ‘short’ or ‘long’ depending on the native “int” format of specific platform.

“SensorValue” intrinsic definition changed from ‘word’ to ‘int’.

Added command line option to deactivate all active, non-building licenses (-DEACTIVATE).

Added quick access, “Add License” menu item.

Debug Stream has been made more robust to prevent buffer overflows and corrupted data.

This is super useful in class room environments, or in my case, a Coderdojo! The kids simply need to click the macro file, which will open ROBOTC with all the settings you’ve setup. If you are targeting Virtual Worlds, you can also select which world should be used.

The RBC Macro Editor allows you to quickly create a ROBOTC Text-Based or Graphical macro file that will pre-configure many aspects of the UI, such as platform, the debugger windows that are to be opened, the default save-as file name and many others. After the packages have been downloaded and installed, they will appear in the virtual world selection menu.

Robot Virtual Worlds Package Manager simplifies keeping your RVW worlds up-to-date and allows you to easily download new ones. ROBOTC 4.32 for Robot Virtual Worlds (VEX):.ROBOTC 4.32 for Robot Virtual Worlds (MINDSTORMS):.ROBOTC 4.32 for MINDSTORMS EV3 and NXT:.Please note that if you use LEGO MINDSTORMS EV3, you must update the Linux Kernel to 1.07X, after which you must update the ROBOTC VM as well, of course. lets say you had four sensors, if the left most sensor sees the line then you could turn the right motor off while if the second sensor from the left sees the line you could simply slow the right motor, this way it would react more abruptly to sharp corners or if it moves farther off the line for some reason.ROBOTC 4.32 is here and it includes a few new features and plenty of bug fixes and enhancements. In addition, if you add even more sensors you could add tiers of adjustments. The optional fourth case would say, if none of the sensors see the line, either turn the motors off or maybe spin until it finds the line again. The third case would say, if the line is under the middle sensor, set both motors to the same speed in an attempt to maintain a straight path. Typically you put the third sensor in the middle and in addition to adjusting like you would with a two sensor line follower, you add a third and even a fourth case.

The idea behind three sensor line following is that it makes the two sensor a little more robust.

The following should give you an idea of what this code would look like, I have not tested this code so proceed with caution.

Time is wasted traveling the extra distance (as opposed to driving straight).

Only works well in a smooth line (no abrupt turns).

If you overshoot the line once it can be disastrous.

When the sensor sees the line, you would speed up the motor closest to the line briefly to keep if from crossing. The general idea behind one sensor line following is that you set one motor to run at a slightly decrease or increase the speed of a motor so that the robot favors one direction (the direction toward the line). Let’s first review the typical sensor options. This is generally the first method people learn when line following because it’s simple to understand and simple to program. First off, we have the simple line follow, the general premise behind this type of line follow is that you have anywhere from one to a few sensors and you hard code a motor response based on which sensor sees the line.
