Reviewer 2 Report
The paper presents a robotics application which was fully developed using open FPGA tools.
This paper is very interesting, and the proposed application (self-balancing robot) very original.
Unlike the microcontroller where free solutions exist to program it, the FPGA market uses proprietary softwares that can only synthesize the FPGAs of the most famous proprietary companys : ISE for Xilink and Quartus for Intel.
On the other hand, the title "Control system in open source FPGA for a self-balancing robot" is confusing. The reader expects to find an open source solution for synthesizing Xilink or Intel FPGAs, while the authors use an Icezum Alhambra II card (including the open-source FPGA iCE40HX4K-TQ144 from Lattice) with the IceStorm tool, which are known by FPGA users.
I propose to mention it in the title and also in the abstract.
