I would like to make a delta robot to control a coconut scraper. May sound funny but this is what I want as my wife have joint problem including the fingers and I want the coconut scrapping to be made automatic or semi automatic. I have been thinking and found that a strong and slow delta robot is the bet option. Coconut scrapping does not need speed in movement but need strength and the distance travel is also only few centimeters (the size of coconut). If willing to help please reply back. Thanks
