Humanoid Demonstration Rules
Audience: Journeyman Level
Humanoid robots strut their stuff in order to impress the judges.
A painted flat level surface will be provided. No exact coefficent of friction is guaranteed.
The robot should be generally humanoid in shape and locomotion. That is, two arms and two legs. Due to the difficulty of humanoid style locomation, robots may be Autonomous OR R/C.
This Penguin Robot was built after the december 2005 issue of Servo Magazine ran an article on "Penguin Evolution." The Penguin Robot was designed by Ken Gracey from Parallax and some Poorly dimensioned CAD drawings were in the magazine for the general public to build their own. Well I got inspired to do so and around October of last year Terry Surma and i set out to build a few "Penguins." The Robots use Nano Servo's for the Tilt and the Stride and i was lucky enough to receive a set of boards for my penguin from Ken Gracey himself.
This Robot spent about 6 months in the design and build phase. It was completely designed in TurboCAD and then laser cut by Terry Surma. The first Prototype is the robot you see in the picture and that is the only prototype. Slowpoke utilizes an ATMEGA32 processor on a DEVBOARD Mega32 from Wright hobbies to do the processing. It has a solarbotics L298 Motor Controller. The Line-Sensor is a CBA Line Following Module (LFM). The Robot is driven by 6 AA batteries and the locomotion is provided by 6 ESCAP motors. This Robot is now a Shelf decoration and
Ryan and I have been working on a lap timer for our contests in October. The timer uses the Chibot controller with a Mega88 MCU, runs on 4 AA batteries (alkaline or rechargeable) and supports 3 sensors. It is designed for 3 modes:
Anklbytr is a Quadruped robot created by CrustCrawler.
I picked it up as a kit for a class that I was taking at Roosevelt University.
Presently Anklbytr walks as if it's severely drunk and is in the middle of dumping the Parallax BS2 and Servo Controller that came with the kit and instead running using the Wright Hobbies Devboard-M32 and a Pololu Micro-SSC. Servo power will be provided by a 7.4v Li-Poly battery instead of the weighty NiMh race packs normally seen in RC cars.
Programming is being done in C++ and also tinkering with FreeRTOS.
