Change Release Notes
- When ez-bits are missing, do not allow user to SKIP. Now first time users must SYNC or CLOSE. Skip is no longer an option.
- Script Flow control bug fix for 3rd party controls. Find out more about script flow by clicking HERE
- Dynamic Turning with camera control Movement Tracking (see below)
This is a fun release because it has a pretty significant update to the camera movement tracking. The movement tracking is a setting in the camera configuration which tells the robot to physically follow the specified tracking type using the movement panel. Of course, a Movement Panel is required in the project for this to work. The old movement tracking would stop the robot and turn toward the object. This new addition uses a Dynamic Turning option. This means the robot will turn toward the object while moving forward. The further the object is to the edge of the screen, the harder the robot will turn in that direction.

1) Enabling this checkbox instructs the camera control to use the Movement Panel and have the robot physically follow the object.
2) Enabling Speed Settings tells the robot to use the specified speeds when tracking with the movement panel. Forward, Left and Right speeds can be specified and tested here.
3) Enabling Dynamic Turning will have the robot turn toward the object at a variable speed. The values in this area are the SLOWEST speed the robot's wheel will turn in that direction. This means SLOWER = MORE TURNING. The further the detected object is from the center grid lines, the faster the robot will turn. Having this number as low as possible is usually best. For Roli, it would be set for a 1
Here is an example of the robot NOT using dynamic turning. Notice how the robot STOPS and TURNS and STOP and TURNS and STOPS and TURNS, etc...
Here is an example of the robot USING dynamic turning. Notice how the robot continues straight while tracking the object...

Any Movement Panel that supports speeds for left and right wheel can use dynamic turning option. Obviously the Movement Panel will need to support the left and right wheel speed settings. If you're using a custom Movement Panel due to some unsupported hardware, ensure your code is using the GetSpeedLeft() and GetSpeedRight() values for your hardware.
The built in sabertooth controller supports speed, so dynamic turning applies. Speed means the speed of what a wheel turns. If you were to go full speed, the wheel will turn X number of times per minute. If you go half speed, the wheel will turn X/2 Per minute, etc.
The speed ability is what allows the robot to dynamically turn.
Without speed ability in a movement panel, there's no way to adjust the speed of a wheel. Controlling the speed of a wheel is necessary for dynamic turning.
A robot cannot dynamically turn if the wheel speeds cannot be controlled. The only way a robot can turn without wheel speed is to stop the wheel.
Stopping a wheel is not dynamic. Stopping a wheel to turn is binary.
Dynamic turning uses the wheel speed to turn. Dynamic turning will slow the wheel down in the direction the robot needs to turn. Without wheel speed control, dynamic turning cannot work and your robot will always move straight.
If there are two speed sliders on the roomba control, then it supports two speeds and will work with dynamic turning.
