Experiential Robotics Challenge

The design adds swerve drive modules to the XRP robot platform.

awesome design, would love to have seen it driving around though :)

Instead of using traditional electric motors to drive the upper and lower gears, a contactless magnetic drive system could be implemented. In this approach, the gears are equipped with permanent magnets, while the base, on which the magnets move, is fitted with controlled electromagnets (magnetic coils).

By generating rotating magnetic fields in a controlled manner, the movement of the gears can be precisely regulated, similar to a stepper motor or a brushless DC motor (BLDC). The mechanical construction itself ensures correct positioning of the components. Initial calibration could be achieved using optical sensors, but in the long term, a closed-loop control system could be integrated directly into the drive mechanism, eliminating the need for external sensors.

This technology has the potential to enable a new type of direct drive system that operates without mechanical wear, is virtually silent, and offers high precision.

Neat design. Kinda reminds me of a core xy, and a differential. I like it's simplicity

[MahirAhmed-Al]

Do you think the coaxial version of it (the green one) will be compatible with small N20 motors?

[milankarakas]

Where to find that two balls? And is that just ping-pong balls or something else?

[Gasykala]

Congrats!!! It looks great, really. I will try to print this coming week.

I was trying to wrap my head around why you would want two different drive systems on a single bot, and what the kinematics would be to keep them synced, then realized I was overthinking it and you are just demoing both. If you want another possible option, instead of 4 motors, maybe you can add cutouts for a TPU belt option to sneak in there to grab a gear from each wheel. Then you could use it as a common pivot driver, and the other two could remain independent. You could probably think of it as kinematics with the training wheels on, but it also needs one less motor assembly to function, can still 360 spin and drive sideways, etc.

Nice work. Idea - make the mechanism in a way that rotating the motor to one side rotates the wheel and changing the motor direction actually spins it - by this you can achieve driving to any direction my single motor :)

Hey wildwilly.
Hvilke uddannelsesvej tog du for at få disse fantastiske kompetencer ?
Jeg overvejer selv Maskinteknik diplomingeniør plus en kandidat i elektroteknologi, også vil jeg selv lære ai, ML og programmering generelt igennem selvstudie. tog du samme vej

[Pokornz]

I would love to hear the pros and cons of the coaxial and differential approach!

[kunalshah]

ohh i had a working version of this i never made a decent yt video of this tho 😢
