Father's Day Handcart

The well known German tradition of father's day hiking (dt. Vatertagswandern) is directly connected to the use of a handcart for transporting the beverage. As this tradition is most favored by men and the handcart has four wheels, there still evolved the guild of fathers-day-handcart-tuners. The most common tuning parts are radios and cooling bags, but I think the sky's the limit.

In the southern part of Germany, a hiking tour through the mountainous region, moving the handcart by HAND, can be very tiring. Therefore, the idea of assembling an electric motor support was born, which outlines the project.

The basic technical drive set-up, has two small electric motors at the two wheels of the rear axle. By using two smaller motors, the set-up gets rid of the need of an differential gear. These motors are driven by two TAPAS boards connected to a standard 12V car battery (now already used for the radio). The controlling is done via a Rasperry-PI, which runs a feedback loop, detecting the current kinematic state and regulating the support power for the motors.

As this sounds like very standard for a drive set-up, the main challenges are:

- Reducing weight and power consumption and

- Making it stable under the rough conditions such a day can bring.

The project team is directly represented by the hiking community, which includes mechanics, technicians, electricians and a physicist.

    Hi Johannes,

    thanks for your submission! The idea using a feedback loop sounds great!
    We want to provide you two TAPAS boards.
    Please keep in mind that the board may not be operated unsupervised. 
    One of my colleague will message you shortly.

    Have you already chose a Motor? Are you going to use a BLDC Motor? How much Speed are you planing to archive? I was planning something pretty similar. Also I was thinking about adding sensors like ultra sonic to check if nothing is in the drive way (for example drunken people ;) ). I'm very interested in your progress and I hope that I also have the possibility to create a cart.

    Hey Johannes & team, 

    Please keep in mind that the submission deadline for your presentation is on 24th of June! We are already looking forward to seeing how you brought the TAPAS board to life! :-) Remember that you still have time to work on the implementation of your idea after the submission!

    Please upload your presentation and everything you want to share with us in your idea board entry.

    Good luck :-)
