In this paper, we develop a brainwave-based control system for Cerebot, consisting of a humanoid robot and a CerebusTM Data Acquisition System up to 128 channels. Under the OpenViBE programming environment, the control system integrates OpenGL, OpenCV, WEBOTS, Choregraph, Central software, and user-developed programs in C++ and Matlab. The proposed system is easy to be expanded or upgraded. Firstly,...
An oil control system based on single chip is introduced in this paper, which mainly uses 80c51f020 microcontroller as the core device, and the MODEL2201D expansion module to coupl PC software. The principal computer uses industrial PC match with MODEL2201D communication module, and The communication between principal computer and lower level computer following RS485 agreement. The preccise oil delivering...
The dynamic reconfiguration technique based on FPGA (field-programmable gate array) can improve the resource utilization. The dynamic reconfiguration principles and methods are discussed. A remote dynamic reconfiguration scheme using Xilinx Virtex-II FPGA and SMCS Ethernet PHY (physical layer transceiver) is proposed. The hardware of system is designed with Xilinx Virtex-IIXC2V30P FPGA that embeds...
A control system for micro-fluidic chip was designed and realized in this paper. The serial controlled A/D and D/A chips were chosen to reduce the amount of control ports. FPGA with plenty of control ports was chosen to be system MCU, on which programming in VerilogHDL, and as a result 30 chips can be controlled synchronously. Communication between PC and USB2.0 high-speed transfer interface chip...
NC program processor is an important module in Computer Numerical Control (CNC) system. NC program processor is divided into interpreter and look-ahead function. In the paper, the macro variable computation, the geometric transformation and the look-ahead pre-interpolation which is widely adopted in machining small-line blocks are introduced for their importance in modern CNC system. The former two...
