Here is the second reduction gear assembly. The motor pinion has 13 teeth and the green nylatron has 72 teeth. This reduction is ~ 5.54. Total 5.54 X 2.88 = 15.9 : 1 .
We decided that the standard motor on the QuadROSbot was not suitable for travelling over rough ground at slow speed - it was more suited to speed rather than torque. The motor chosen for the upgrade was a 3 phase 48 V DC motor with a 5:1 planetary gearbox...

In previous projects we spent a lot of time designing and building the mechanical systems and we really wanted to short cut all the hard work by using a ready made system that could be bought reasonably cheaply 'off the shelf'. We looked at mobility...

The levers and motor gears need to be printed using a high resolution method such as SLS nylon. This is because of the detail needed in the shape of the gear teeth (involute) that allows the set to move smoothly. Fit the PTFE bush into the pivot hole,...
