We are Cougar Robotics 4251 and this is for the Instructables Sponsorship Program.
(sidenote: the images in this are mostly of an old Samantha module, new pictures coming soon. The bracket works exactly the same with the new Samantha)
In FTC, many robots disconnect from the field control system during the pushing and bumping of a normal match. In this Instructable, we will go over the single weakest link in the control chain and how to make it significantly stronger. That weak link is the wires coming out of the Samantha unit. Here we will show you how to strengthen that connection to the point where it should significantly reduce the nubmer of field disconnects your robot suffers, it certainly has for us. These instructions are similar and based off of the instructions for FTC best practices on usfirst.org
Things you will need:
1. a Samantha mounting bracket (CAD file below) or a 6x2 Tetrix flat plate
2. the Samantha unit
3. Samantha power wire
4. a short USB extension cable (we generally use 1')
5. 2 gear hub spacers
6. some small zip ties
Step 1: Attach Samantha to Bracket
The first step (once you have all of your pieces) is to actually attach the Samantha unit to your bracket. This can be done with two of the small standard Tetrix screws or with 2 small zip ties. It is important that the wire ports are facing the rest of the bracket so that you can support the wires coming out of them.
