The finished design for his Linear Actuator (LA), made of discrete elements, is an evolution of the initial experiments shown on the original post.
This would be better called a Track Actuator (TA) as he explained to me. Technically a TA consist of a moving "car", while LA features an expanding/contracting rod. Nevertheless it would be easy to attach a rod (axle or bricks) to the moving "car", turning it into a LA too.
This new design also has now already some months and it was originally planned to be a new product release, on sale at Mauricio's store (iLegos). Then we discussed some design details, the time passed and here it is today...
According to Mauricio, this design was inspired on another LA design suggested by Alexandre (AVCampos), that was also shown before here
Beauty and ingenious this idea, on how the stop points problem at each LA end was solved, to
No need for the LEGO clutch or switches. The springs make a nice work freeing the motor from any kind of extra effort or overload and allowing the "car" back in movement after the motor direction is changed.
We have discussed smal
Below, the results.
