This week, i was able to synchronize cyton arm movements creating a new ROS node to control the speed of each joint. I also designed a new gripper with the possibility to attach 2 Force Sensing Resistor.

9th week: FSR
This week, using an arduino (communicating with PC via TCP/IP) and 3 voltage divider I was able to connect 3 Force Sensing Resistor (FSR). I provisionally installed the sensors and started doing experimental tests so i can later control the robotic gripper movements -grab, hold and drop objects.
8th week: Kinect – hand tracker
This week, I worked with Kinect and used openni_tracker package to track my hand coordinates, so i can set those coordinates as the desired goal for cyton end effector position.
7th week: Cyton IK
The work I did in the past 3 weeks was a turning point as this week I could finally get the inverse kinematics and Jacobian for Cyton applying a KDL solver. This means I’m now able to move the robot to a desired end effector coordinates inside it’s workspace.
6th week: MoveIt! setup
This week, using MoveIt! tutorials I was able to create a Semantic Robot Description Format (SRDF) and a few additional configuration files for Cyton gamma 1500. With these files it will be possible to use the MoveIt package to calculate the inverse kinematics.
5th week: Dynamixel Controller
This week, I created the controller for Cyton dynamixel servos following the ROS dynamixel tutorials. These tutorials describe how to connect and examine raw feedback from Robotis Dynamixel servos.
4th week: FS holder
This week, I used CATIA v5 software to create a prototype which enable me to hold the force sensor in the robot’s arm.
