Microbot Mechanical Design Guide

Microbot Mechanical Design Guide

Wheels: Outer Diameter: 10.6mm Thickness: 2mm O-ring groove diameter: 1.8mm O-ring groove inner diameter: 9mm Center mounting hole:  2mm diameter – ideally with .5mm D cut or wheel may spin on shaft Chassis:  Starting Body Extrusion: 19mm width, 23.5mm length, 16mm height Top Cutout subtraction: 17mm width, 21.5mm length, 8mm height – this should leave you with 1mm thick walls on all four sides Motor hole size: 6.15mm diameter – motor is 6mm so 6.15mm gives us a little clearance Motor hole position:…

Timing Belt Design Information

Timing Belt Design Information

Timing belts can be great at moving power around, and changing speed/torque from source to destination. They can also be tricky to work with. The standard belt size used on FIRST robots is 5M-HTD 15mm wide belt The_World_of_Timing_Belts – This design guide from Gates is very helpful. Some Suppliers: http://polybelt.com /

WS2811 RGB Light Strips

WS2811 RGB Light Strips

The WS281X series light strips are great for creative lighting. The strips have individually addressable LEDs which can be programmed through software such as arduino. You’ll need to download libraries for the chips that are on the LEDs in order to address them. These are easy to come across in a short web search, I personally ended up using a site called FastLED, it’s quite helpful if you’re doing this for the first time as there is a FastLED Google+…
