Take a look here to see more details. Getting that video wasn’t all that easy.  We ended up writing software to keep DoofusContinue reading “PJD is ready for the farm!”

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.

Now that’s done, work can start on the lower priority stuff. *I would like to say that no robots were hurt in the making of this component. However, a certain Hexbug from PiDrogen HQ has had betterContinue reading “A vital part of PJD is now working”
