I thought I would start downloading some pictures of the new Saint build.


Firstly the motors used in this project, the old Saint A used the Bosch 750 units but for an axel robot there has never been enough power , so we are using the Mag motor it has three times the power of the Bosches but the penalty for this is extra weight.

The wheel hubs are always a cause for concern on the larger wheel robot, as the stresses on these parts are always large. We have decided to stick with the trailer hub design as with Saint A they have never failed in combat and with the taper roller type bearings they are best placed to accept the axial loads expected.

I always like to have the drive as an assembly that can be removed complete from the robot, here are the drive units complete and ready for the next stage of construction. you can see the gearboxes made by Mike the final drive is 1/2 inch chain similar to Saint A

Then parts on the garage floor trying to work out the width of the robot and how we are going to squeeze all the bits in, the finned aluminium is the passive heat-sink for the Wotty speed controller.
