Overview of new steering proposal
Figure 1. New steering part maintaining original steering axle position, but replacing with bearings and a belt drive to a maxon gear motor. This figure points to most of the off-the-shelf parts used.
See purchase detail in Terrain-hopper binder (Christian office - red binder).
Figure 2. New steering part maintaining original steering axle position, but replacing with bearings and a belt drive to a maxon gear motor. This figure points to most of the parts that needs workshop assistance. Most of the parts - except axlesl (7 and 8) - can be manufactored on own workshop. The axles will be manufactored by axle supplier.
Maxon motor
The motor for steering is a Gear-motor-encoder combination from Maxon:
