'''Motor''' blocks are blocks which controls the motors on Buggy Base directly. This gives the user the ability to fine tune the behavior of the motors. The motors are referenced as Motor "A" or "B" depending on the side it resides. These blocks can set the movement direction of the motors ('''Motor - Set Speed''' block) or brake / stop the motors ('''Motor - Stop''' block).

Car

Car blocks are blocks which controls both of the motors at the same time in order to move the forward / backwards (Car - Move block) or turn left / right (Car - Turn block). These are convenience functions designed to be "general purpose". Motors can be controlled directly with the Motor blocks. See section #Motors.

Block: Move

The Car's movement direction can be controlled using the Car - Move block.

Note: This block is holding. Which means the movement time (as set by Duration) must complete before the program goes to the next block in the script.

Function: This blocks controls the Buggy Base to move either forward or backwards at a certain speed for a specified duration.

IBB mDesigner Car Block Direction Speed Duration.png
  • Direction - direction to move. Either forward or backward.
  • Speed - rate of the motors when moving. A value between 0 and 255. 0 being off, 255 being full speed, and 127 being half speed.
  • Duration - amount of time (in seconds) to move.

Example 1: Set move direction of Buggy Base

Description: When activated, Buggy Base will repeatedly move forward at half speed (127) for 2 seconds, then move backwards at half speed (127) for 2 seconds.

Block: Turn

The Car can be set to turn using the Car - Turn block.

Note: This block is holding. Which means the movement time (as set by Duration) must complete before the program goes to the next block in the script.

Function: This blocks controls the Buggy Base to turn either right or left at a certain speed for a specified duration.

IBB mDesigner Car Block Turn Speed Duration.png
  • Turn Direction - direction to turn. Either left or right.
  • Speed - rate of the motors when turning. A value between 0 and 255. 0 being off, 255 being full speed, and 127 being half speed.

Example 3: Turning left
