Change Release Notes

This release includes a significant update to the servo manager. The servo manager for all robot skills now includes advanced settings in the Advanced button when editing servos. The button was renamed from Multi servo to Advanced due to the addition of new features.

User-inserted image

Pressing this button when editing servos for a robot skill will present a new improved multi servo menu. The new menu provides the same functionality of being able to add multiple servos, but also specifying advanced parameters. The parameters are displayed whether or not the servo or EZB supports the parameters. Due note that not all servos or EZBs support the Velocity, Acceleration, and Speed parameters. Check with the robot skill driver or EZB firmware capability for support.

User-inserted image

The new parameters have question marks next to them. This is important to notice that the value of -1 means "ignore". This is similar to how the Auto Position treats -1 for speed parameters.

User-inserted image

The Auto Position has also been updated to allow specifying of the new advanced parameters for frames added to an action. The parameters can be edited or specified when adding a frame to the list.

Other Changes:

  • cheatsheet doesn't quote the parameter list because it was making commands with multiple parameters not quoted

  • removed the built-in mip Movement Panel because there's a new improved v2 robot skill
