Monty recently visited the
í°»Jasmineí°… is the universityí°«s swarm robot platform. Includes IR transceivers for communication and object sensing. There are 6 emitter-detector pairs. This provides 360-degree view, but has a non-linear radiation pattern. The communication range depends on the orientation of the robots. Synchronizing Tx and Rx channels involves complex protocols, one channels at a time. A buffered shift-register is used to drive the emitters.
The drivetrain is a simple construction using Solarbotics GM15 motors (basically pager motors with a planetary gearhead with a 25:1 reduction).
The power source is a 250mah Lithium polymer battery.
Measuring distance and angles: Distance measurement is based on reflected light intensity. Good motion control allows angle measurement. Work is in progress on algorithms for object geometry measurement and feature extraction. One robot cannot reliably classify a surface, but a swarm of robots can work collaboratively to share information about each botí°«s perception of the surface.
Whatí°«s Next: í°»Jasmine IIIí°… will integrate the sensor and controller board and improve sensor range. í°»Jasmine IVí°… will improve modularity, improve the chassis and drivetrain. The university is working on an í°»autochargerí°… system.
Research initiatives: Jasmine is part of a larger research project called í°»I-Swarmí°…, focused on nano-robotics.
Swarm Games would allow individuals to build a small number of robots, but collaborate with others on swarm behaviors. Competition ideas include:
1. ball games
2. capture the flag
4. searching games
FIRST robotics competition is in progress at the
Paul V., president of Boise Robotics Group visited the
meeting while in town for the FIRST competition. He strongly recommends volunteering in
FIRST. He brought in a sample of their
í°»Bread botí°… kit, based on Basic Stamp and a large
prototyping breadboard. He discussed a
Pete Skeggs brought in a sample of the MaxBotics (maxbotics.com) sonar sensor. Includes RS232 and analogue output. Pete is involved in the development of a robotic dinosaur, which was displayed at í°»Demo 06í°…. The robot, í°»Pleoí°… won awards at the show. Pete demoed a prototype of the Pleo robot.
Mark Medonis brought in copies of 3d cad software available for non-profit use by PARTS members.
Tim discussed using optical mouse sensors for robotics. Heí°«s trying to use a laser optical mouse sensor in a mini sumo platform. See www.ilda.net/users/oe1k/OpticalMouse
