Flexible Automated Workcell: Industrial Assemblies

In this new demo, the robotic workcell is used as a single unit capable of recognizing and performing assembly tasks. Vision sensors identify input "empty" assemblies and direct the robotic arms to work cooperatively in putting the pieces together and exporting a finished product. The first assembly contains a notched piece of wood with four small blocks that fit neatly into the notches. The second assembly involves a piece of hard foam with holes into which fit four bolts. The assemblies and parts are not in a designated position - instead the overhead camera computes their locations each time the parts are assembled. See the video here - workcell_assembly.avi (34M)

 

Available for download and viewing here is our demonstration video featuring three cooperative robotic projects. Download robotdemo.avi (about 26M). Project descriptions can be read below.

Follow the Leader

In this demonstration, the overhead-mounted Cognex vision system communicates to the robots where a block of wood is located in the workspace and they then pick it up cooperatively. One robot then moves a millimeter to one side. The other robot senses the motion through the ATI Force/Torque Sensor attached to its end effector and moves a millimeter to compensate for the motion. Using this step-wise procedure, one robot effectively leads the other across the workspace.

Cooperative Work

In the first part of this demonstration, the robots work together to jointly assemble a nut and bolt. In the second part, one robot picks up a rod and hands it to the other robot, which replaces the rod in its initial position. This is repeated a few times.

Boxing

Here the robots act out a quick boxing match. No robot was harmed in the filming of this video.

 

Lego Mindstorms

These demonstrations show various projects implemented using the labs' RIS kits. The first featured invention is a conveyor belt sorting machine that distinguishes between green and yellow "packages." The second demonstration features a pair of purely reactive mobile robots interacting within a closed arena. Download legodemo.avi (about 16M)

 

Mobile Micro Robots

This demonstration shows the lab's two mobile micro robots navigating through an obstacle course using simple reactive programs. Both robots are detecting the obstacles with infrared proximity detectors. The video also shows the robot's differences in size and speed.

These five videos demonstrate the capabilities of the tracked robot. Traversing an Obstacle (about 1M)

Navigating a Course (about 4M)

Crossing a Gap (316K)

Going over a Cliff (626K)

Moving Around (about 2M)

 

Swarm Robotics

These demonstration videos show swarm robotics in action. They robots were built using Lego Mindstorms. The first video shows the small mobile robots following a beam of light. Download (about 8M) The second video demonstrates communication between mobile robots with two of the robots mirroring the movements of the third. Download (about 8M) The third video demonstrates the swarm collecting and moving items from an arena. Download (about 3M)
