FPGA and robotics enthusiast ZaIoNeL has created a grasping, clamping robotic arm that has six degrees of freedom alongside a spherical wrist for maximum dexterity. On the hardware front, he’s using a keyboard, two Altera FPGAs, two Xbee modules, power supply, and of course the robotic arm.
The robo-arm project uses a couple of Altera FPGA boards and a wireless control system using a system-on-chip. This consists of a NIOS processor, an SPI module to communicate with the sensors, and a serial communication module to receive wireless commands sent from a remote controller.
