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,...

Step 2: Wheels and TrucksIn this build, I used 90 mm ABEC Flywheels with these gears from Thingiverse. (Designer: brentyi) The design I chose was the HTD5 9 mm 40 Teeth gear. They require 6 x M5 x 73 mm Socket Screws and 6 X M5 Nylock Nuts. Once you...

Eitherget a UBW32 for the CPU. plenty of online retailers for this. proceed to step 2, orget an Olimex Duinomite-mini (which I use), or Duinomite with the IO adapater (which I do not have, but reportedly it also works). If you use these boards,...
Using a #2 phillips screw driver, remove the two mounting screws from the stack light. Fish the wire bundle through the large hole in the top enclosure piece. Use the two mounting screws to attach the top enclosure to the stack light.Trim...
tl;dr; Open the LED strip controller from the bottomI got the LED strip off of Amazon and it seems like most of the strips use a very similar control module with an IR remote. A simple screwdriver is all it takes to pop off the bottom lid and inside...
DFRobot was generous enough to send me two of their MiniQ Robot chassis. The chassis have plenty of mounting holes that allow you to add brackets. They come with two motors and wheels, along with two sets of caster wheels to add strength. The assembly...
I'm using GIMP, just because I have used it a few times. It is easy enough to get used to, especially when you can google just about anything you want to do on it. First, I need to decide which colours can be merged into one. I have 4 colours to work...
Set the motor mount retainer on top of the stepper motor and attach with 4 x M3 screws. Press-fit the 5 : 1 sun gear with the motor shaft axle to the stepper motor shaft. (note: the motor mount STL doesn't have the four holes in the plate right...
