🎉We can now proudly present the winners of the TAPAS Community Challenge 2018! 🎉
Congratulations to Team "Wireless Charging" (idea 56). We are really excited for all finalists and a really big thank you to all participants for your interest in this challenge!

We got over 200 submissions! 65 ideas got one or more TAPAS boards, 10 submissions were presentation-ready.
And now we have 5 finalists! YEAH 😃 The finalist's idea numbers were 40, 56, 68, 212 and 213.
What's next?
We are now preparing the next steps for you, the community. Please stay tuned!
We are working on a forum and a separate webpage. If you have any question please don't hesitate to contact us via email!

Digging ram

Cables are sometimes buried using a worm-like probe called a mole which drives its way through the soil using a reciprocating slide-hammer, often powered by compressed air in the manner of the moving mass in a vibratory poker.

As in most fields, energy transfer (in this case to push aside the surrounding soil) is best when matched to the load - thus the vibratory stroke length, frequency and speed should be optimised for the water content and weight of the substrate.

This idea uses a BLDC in the form of a linear actuator to accelerate the moving weight, allowing the velocity profile to be tailored to the job. A further BLDC actuator might be used to modify the attack angle and provide steering.

The motion could be developed using a single TAPAS  board to control the linear actuator, but an additional board would be required for steering  control.

    Hey Adrian,

    you seem to have many interests ;-) Are you working in team? 
    Also this idea sound interesting, but we need again more details...
    Can you get a little deeper into the technical site and explain your set-up and the usage of the TAPAS board? Can you provide a sketch or diagram.

    Thank you!
    Nora @ TAPAS team
