Hi, thanks for the reply. I haven't got a question about any one particular part. I'll have a go at creating my own wiring schematic when I've got all the parts ready. I've just ordered a guzunty so that's one part less on my shopping list.
Thanks for a really good article. I'd like to have a go at building the robot and implementing the OpenCV image recognition (demands of work not withstanding). Can you post a more detailed list of the parts you used for the robot?
