Yesterday, I attended the EuroGamer Expo (EGX), 2014, at the Earls Court Exhibition Center in London, U.K. The journey up to London, by train, did not start too well, due to works being carried out on the railway tracks. This meant that we first had to go to Brighton to catch another train up to London. Hence, a journey that should have taken an hour and a half ended up taking about three hours. When we got to London Victoria Station the Circle and District underground lines were closed, which meant taking the C1 bus to Earls Court and us arriving almost an hour and a half late.
Hello and welcome to another post in the blog series on using FPGAs in Robotics. So far the series has concentrated on the construction of a 17 DOF robotic kit, which was purchased without any assembly instructions. This kit, when fully constructed, will be central to this series of blog posts and should be controlled using one of Altera's Cyclone family of FPGAs on a development board or kit. In this blog post I will finish the construction of the lower limbs and add the waist bracket, which will eventually act as our Inertial Frame when the Denavit-Hartenberg parametric representation of articulated joints is considered.

Today should have been a day of great delight as my personal supercomputer, or Parallella the Epiphany III processor with Xilinx Zynq 7020 FPGA, finally appeared in my hands after many months of delay. However, I wasn't exactly jumping up and down with joy for, as like most "supercomputing for everyone" enthusiasts, I was suffering from "where is my Parallella" fatigue.
Parallella first appeared as a Kickstarter project, in October 2012, where it did wonderfully well in raising $898,921 in its allocated fund raising slot. However, at the time I didn't back the project, as the $3 million stretch goal required for the production run of the 64-core version, the Epiphany IV processor, was not met.
You can read about my observations using the Parallela kit in the Blog Category: The Parallella Post. Also, you can read about my projects using the Parallella kit in the Project Series - The Parallella Chronicles (link coming soon).

To alleviate the poverty of flexibility in our existing design, described in previous parts of the tutorial, a revision to the design has had to be considered. This has resulted in the development of a transmission arbitration module. Thus, the overall objectives of part six, of tutorial series 1, is to firstly design and implement a round-robin transmission slot arbitration module that can be used in conjunction with the UART module developed previously. Then, secondly, a real-world example should be demonstrated on the DE0-Nano Development Kit platform.
