Robots and Physical Computing

In a previous post ( http://robotsandphysicalcomputing.blogspot.co.uk/2016/05/playing-7bot-robot-arm.html ) I discussed starting to set up the 7bot robot arm ( https://www.kickstarter.com/projects/1128055363/7bot-a-powerful-desktop-robot-arm-for-future-inven ) . I have still to set up the gripper. This post document my first tentative steps with playing with it. The code below was used to try and get my head around the positioning of the arm - which servo does what (a good guide for this has been provide by the company online) and what the changing angle on the servos actual does. Essentially the code puts the arm in a starting position and varies the angles from there in usually in 15 or 30 degree increments over seven positions. #include <Servo.h> #include <DueFlashStorage.h> #include <Arm7Bot.h> Arm7Bot Arm; void setup() {   // initial 7Bot Arm   Arm.initialMove(); } void loop() {   // set motor[0] speed to 100   Arm.maxSpeed[0] ...

The 7bot is a recent kickstarter project  https://www.kickstarter.com/projects/1128055363/7bot-a-powerful-desktop-robot-arm-for-future-inven  from 7bot. A metal robot arm based around Arduino Due ( https://www.arduino.cc/en/Guide/ArduinoDue   ) . Development of the software, at the time of writing, is still ongoing but looks interesting and already on the comments page of the site, user's have started posted their code.  Had to install the following software and put the un-zipped files in the library folder of the Arduino folder. https://github.com/7Bot https://github.com/sebnil/DueFlashStorage   Some useful information of setting up using the Arduino Due is available at  https://www.arduino.cc/en/Guide/ArduinoDue  and is definitely worth a read - it helped me setting it up. At the moment I have just used the examples from the GitHub site and example is shown in the video below. This looks like an exciting little arm and hopefully there ...
