After some work and different initial concepts, the first complete Tabbot design is finally finished!

These are the different views of the 3D model:

It has two motors with its wheels and a third castor wheel for support. The base is laser-cut acrylic and the tube supporting the tablet, PVC. The rest of the pieces are 3D-printed. The whole model has been designed using FreeCad.

Next step: print everything, buy the PVC and cut the acrylic!
