I made two XRP mods, what do you think of them?

Hello,

I recently made the following two 3D printable mods for the XRP kit and I would like to know what XRP users think of them

The first mod is a set of legs that one can attach to the XRP frame. It uses the two motors from the kit to actuate, and they control like wheels, but still give good mobility on rough terrain.

The second model is an actuator in the shape of a mouth that allows to move things around. It uses the kit’s servo, is easy to use and has a place to add additional sensors. This model requires no extra hardware besides the XRP kit and 3D printed pieces.

The models can be downloaded at:

The source files are available, so one can modify the parts to suit their needs.

Let me know what you think of them. Is it something that you see using with your XRP kit ?

I can’t understand from the video, how it is moving. Can’t see the battery.

I love these, well done!

I’d say both of these mods have legs

So the XRP motors on each side of the frame turn a small gears, which actuate a big gear in the middle. That gear is connected to a camshaft that moves the legs. The legs are made so that the rotation motion of the camshaft is transformed into a walking motion. See https://www.diywalkers.com/strider-linkage-plans.html for more information. I got the idea of the mechanical linkage there. You can also go on the project’s onshape page (link on the printables page) to move the assembly by yourself, it might be the easiest way to understand the mechanism.

The batteries are hidden under the central frame, exactly how the standard XRP kit puts them.
