G-ROB, a six-axis robotic arm based automated system for crystallography

FPGA Based Robotic Arm With Six Degrees of Freedom

The purpose of the project is to build a multipurpose robotic arm which can perform operations with higher accuracy with 6 degrees of freedom. The arm will exhibit higher speed of operation and lower delay in processing due to the use of FPGA for processing and control. This will improve speed of operation and reduce the latency of response when used for applications such as bionic arm when com...

Control of a 2-DoF robotic arm using a P300-based brain-computer interface

In this study, a novel control algorithm, based on a P300-based brain-computer interface (BCI) is fully developed to control a 2-DoF robotic arm. Eight subjects including 5 men and 3 women perform a 2-dimensional target tracking in a simulated environment. Their EEG (Electroencephalography) signals from visual cortex are recorded and P300 components are extracted and evaluated to perform a real...

Controller Design for a Robotic Arm System

Robotic Sensor System for Automated Machines

Flexipicker robots, as well as many automated multi-axis machines, operate under overall ‘open loop’ control. The exact position in space of the end effecter or tool head is not sensed directly. The software controlling the robot or automated machine makes a calculated estimate of where the tool-head should be. This is often achieved by monitoring sensors on axes that track linear translation a...

Neuron-Based Control Mechanisms for a Robotic Arm and Hand

A robotic arm and hand controlled by simulated neurons is presented. The robot makes use of a biological neuron simulator using a point neural model. The neurons and synapses are organised to create a finite state automaton including neural inputs from sensors, and outputs to effectors. The robot performs a simple pick-and-place task. This work is a proof of concept study for a longer term appr...
