Back in December we blogged that our Mk1 chassis was too slow, so we had started development of Mk2. Well, here it is!
In this design, the motors drive the track sprockets directly, with no reduction gearing. This results in a top speed of 1.2m/s; the same as P21. Hopefully that will be fast enough.
Furthermore, the chassis can be used with two motors (and tracks), or four motors (with mecanum wheels). So the new design is far more flexible.
The downside is that there’s far less room for the electronics. I might have to bite the bullet and learn KiCAD.
