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 .
Follow the line between the teeth, then straight back after the teeth until you get to the shaded area, then try to cut as close to the main skull as possible.
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...

Depending on the type of linkage you are using for the jaw, you will need to make a small hole near the back of the teeth for the linkage to attach. From here, test and adjust the linkage for the jaw to make sure you can close the jaw completely...
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,...
The respiration monitor electronics are built into a clear ultra-thin custom retainer. This retainer keeps the sensors and other electronics correctly positioned and also acts as a protective barrier between the electronics and the sensitive skin inside...
The PCB test pads that you need to solder are on the exposed side the the PCB, but all those cool chips are on the hidden reverse side. If you are like me you will definitely want to take a look. Carefully push back the plastic teeth retaining the PCB....
