Pete has been working on several months as a consultant for a robotics toy development company. The robot, í°»Pleoí°… won the í°»Demo Godí°… award at the í°»Demo 06í°… trade show. Pete brought in the first working prototype of Pleo. Pleo can run pre-programmed routines, includes numerous sensors, and plays sound samples.
Pete described the various considerations and problems of developing this toy demo.
Controller board: The demo uses off-the-shelf Olimex Atmel 128 board plus custom development card.
Servo Controller: The demo uses Pololu micro serial servo controller. .
Power subsystem: 5 high-capacity Ni-MH batteries.
Designing the daughter card hardware: Pete needed to integrate SRAM, digital-to-analog converter (using i2c), SD Card (SPI interface), 3.3v regulator (SD Card needs this). A consultant provided the final schematic and board layout.
Ā∑ Behavior Engine
Ā∑ Motion player
Ā∑ Motion data to servo joint mapper
Ā∑ Sound player
Ā∑ Sensor monitoring, debouncing, actuation testing
Ā∑ Buffered serial I/O, various interrupt handlers.
Software development: C-code, 5000 lines, 29 files. JTAG ICE debugger.
Monty Goodson displayed a prototype nanobot chassis based on his MegaBitty controller board. The chassis will include gearhead pager motors and a Li-Po battery. Monty also displayed a prototype of an IR range finding system and remote control system.
Larry Geib recommends the book í°»Linux Roboticsí°…. Larry also recommends a visit to the í°»Robot Hutí°… museum outside of Spokane, WA. Call ahead for a reservation.
Jonathan Fant of Future Robotics introduced his new USB PIC based servo motor controller with a 3A DC motor driver daughter board. Future Robotics will sell the boards as a kit (through-hole soldering required) with a PIC development tools CD. A 4-channel motor driver daughter board is under development.
Mark Medonis demonstrated his animatronic head Maxwell. This month, he is using $200 LCD screen intended for in-car PCs. (logicsupply.com)
A reporter from the NW Examiner is developing a story about our May Enthusiast event. If you have any stories to share, contact firstname.lastname@example.org.
Mike from the surplus shop í°»Surplus Gismosí°… visited the meeting with some surplus boards to give away to club members.
Steve brought in a bot based on the Vex kit. VEX is currently ĀĹ price in the stores. The included SW development kit is drag-and-drop based. Alternative programming tools are available as an add-on.
Rocko brought in several of his PIC robots and discussed some challenges in their development.
Two members of the Clark College Robotic club attended and displayed a tank-style bot. The robot seeks an IR beacon using a custom analog IR homing circuitry developed for a class project. clarkrobotics.com
