Passive VS Active Attachments
Overview
Thank you for visiting our blog. We'd like to share the different strategies that can be used to make attachments. We have used the combination of passive attachments and active attachments many times last year. So we’d like to share what we have learned.Â
Passive Attachments
Passive Attachments are attachments that do not need motors to work. Passive Attachments are very useful for simple missions that don’t need the power of a motor. Passive Attachments need an anchor to work which is usually the model. Passive Attachments use the force of the robot and physics work properly.
Active Attachments
Active Attachments are a type of attachment that depends on an additional motor to move. Active attachments move around more than passive attachments and can use gears, unlike most passive attachments. Active attachments are mostly used when attachments need to be moved without using an anchor. One of the biggest pros fo4 active attachments is that they are independent and don’t need an anchor to move. While active attachments have many pros, people should consider that you need extra motors. The limit in FLL is that there is a maximum of four motors on a robot. This makes active attachments less efficient.Â
Conclusion
In FLL there is only a limit of 4 motors 2 for moving and 2 for attachments with the combination of active and passive attachments we can accomplish a lot of missions with the limit of 2 motors. With passive attachments we can use less motors, and with active attachments we have to add an additional motor, but you can do more complex missions without an anchor. Last year we used the combination of active and passive attachments. Here is a video from last year.
Use passive attachments if… The mission is not too complex and there is an anchor in the model.
Use active attachments if… It is a much more complex mission and it doesn’t have an anchor
This year we are doing superpowered in FLL. To follow us along on our FLL journey, please subscribe to our channel.
