5. Automated Window Openers
Automated window openers offer the ability to open and close windows into the desired position at any given time for improved convenience, comfort, safety, and security. Linear electric actuators can often be found in buildings providing linear motion as the driving force when changing window positions. With all the different control boxes available, options such as the PA-35 WiFi Control Box enables the use of smartphones to control the actuators that raise and lower windows.
A great example displaying the convenience an automatic window opener can offer is found in the video below by the AutoWindows team:
6. Automated Doors
Automated doors share similarities with automated windows as both help improve convenience, comfort, safety, and security; however, heavier duty linear actuators are generally required for the doors. Having a higher force rating on linear electric actuators ensures there is sufficient drive to move the heavier door while keeping it locked if extra security was needed.

Boatsheds offer the benefit of keeping a boat covered to stay clean and dry for future use. Moving a boat shed by hand usually takes a significant amount of time and manual labor, however, linear electric actuators make the process of covering a boat much easier. With the use of remote-controlled systems, users can control the position of their electric actuators for the linear motion to raise boat sheds when moving their boats. After returning the boats, an operator can remotely control their electric actuators and lower the boat sheds for added cover.

8. Solar Trackers
The solar tracker project above by Matthew from Indian Garden Farms was driven by our PA-17-20-850 heavy duty linear actuator. Solar panels help to reduce our environmental footprint by introducing clean and renewable energy solutions. Linear actuators with solar trackers can be integrated to position solar panels for increased power yield by accounting for the changing direction of sun rays throughout the day. By using multiple actuators, solar panels can also be positioned vertically to minimize the risk of panel damage during hailstorms or heavy snowfall.

During the solar tracker’s lifespan, Matthew experienced increased power yields thanks to the actuator providing linear drive to move the panels into the optimized position. Matthew’s area has been experiencing much heavier winds over the last 2 to 3 years. Due to this, the wind eventually tore the mounts attached to the actuator and sometimes snaps the array’s framing. Upon further inspection, Matthew found that the PA-17 unit was still in good condition and operational, even after experiencing lots of heavy winds in various weather conditions. Matthew has been very impressed with the PA-17 model as they performed above expectations and would still be in service if the solar tracker had stronger framing. This PA-17 unit is now in storage; however, Matthew may take on this project again with more durable framing in the future.
Our team has also made a how-to video as a guide for a smaller and more portable solar tracker project utilizing linear servo controls:
9. Movie Robots
Linear servos are commonly used for operating the movie robots found in conventions, amusement parks, carnivals, or during the making of new movies. Having impressive eye-catching robots in movies can often help bring joy to fans while also promoting creative thinking to the audience. Perhaps one of the most popular examples is the Disney character named Wall-E. To replicate the appearance of a real Wall-E robot, Mike Senna and Michael McMaster used PA-14 actuators for the linear motion to move Wall-E’s head and arm.
The Wall-E arm and head movements can also be found in the demonstration video below:
Both McMaster and Senna are working on multiple other projects, most of them being new robot designs. However, they do hope to add more functionality to their real-life Wall-E as time allows. For more upcoming projects, feel free to follow Mike Senna and Michael McMaster on Youtube!
