Winboni, A Window Cleaning Robot

[youtube=http://www.youtube.com/watch?v=1kchwH-3tY0]

The Winboni is the first place winner in the International Student Design Competition of the American Society of Mechanical Engineers. Winboni is a small robot that cleans windows. That alone doesn’t set the robot apart. The fact that it is held on by suction is what distinguishes it. Running off AA batteries, this robot clings to the window as it cleans it with felt pads. It is hard to believe that this isn’t already a commercial product. Actually, we thought we had even seen it before, but we can’t find it now.

Point Laser, Get Beer

[vimeo 777847]

Simply tag something with a laser and El-E will go get it for you. We know this is for the disabled, but we can’t help but think of how nice it would be to have around the house. The system is programmed to recognize the illumination from a green laser and is constructed to be able to reach things from the floor as well as tables and shelves. I wonder if they have programmed El-E to go get the laser for you if you leave it somewhere, kind of like when you leave the TV remote across the room.

Roborama 2008b

guys2

The Dallas Personal Robotics Group held their semi-annual Roborama contest on Saturday November 22nd in Garland, TX. The DPRG had a table at the recent Austin Makers Faire. Each spring and fall, they hold the Roborama contests for autonomous robots. The spring event has contests for outdoor self-navigating robots. The 2008b contests were designed to test the abilities of indoor robots. Normally held at the Science Place, this year they elected to have the contests at the DPRG warehouse in Garland.

Vacuum Micromouse

micromouse

Micromouse competitions have been running in Japan since 1980. In all that time, the ruleset has remained essentially unchanged. The autonomous robot mouse navigates a 16×16 maze creating a map. It then determines the optimal solution for future runs. Current records are in the six to seven second range. Teams have had to find new ways to generate traction for better times. Momoco08 uses a fan to hold the mouse to the track surface. Embedded below you’ll find a video of it solving the maze plus a photo of the vacuum skirt.

Hey, Look There, A Dancing Robot.

People often accuse the computer of cheating when it is the opponent. This could be partially attributed to the fact that you don’t have a physical representation to identify with, the computer seems like an all knowing adversary that divines your moves from the aether. The chief cook actually does try to cheat though. They’ve trained it to play pong, all the while trying to distract you. Upon winning, it lashes out the insults pretty well too. We’ve seen the chief cook before. Last time, he was learning to cook. What will his next adventure be?

Tennis Ball Fetcher

tennisball

Reader [Julian von Mendel] and his team built this tennis ball fetching robot for a competition (translated). The first version used distance sensors to locate the tennis balls for pick-up, but they changed to a camera based approach. The robot has three omniwheels and is designed to calculate the shortest path to the ball despite orientation since it can rotate while traveling. The wheels are monitored using rotation sensors from PS/2 mice. The control is provided by 3 Atmel microcontrollers that communicate via SPI. The multiprocessor design is fairly generic and could be reused for a different style of robot. While their robot performed fairly well, there were some shortcomings. The limited storage space meant frequent trips to drop off balls. The tilting bucket kept them from picking up tennis balls that were against the wall. Also, the bot had to be disassembled for battery swaps. The project is very well documented and they’ve released all of their control code. You can see the robot retrieving a ball after the break.

Cythbot, Pneumatic Guitar Hero

cythbot

Here’s yet another robot hoping to dominate the human race through the power of ROCK. Cythbot was built to demonstrate Cyth Systems machine vision systems. The device uses a camera to watch the Guitar Hero monitor and identify notes for button presses. The strum bar is then triggered after a delay. The notes are identified solely by pixel intensity since star power can cause them to change shape and color. All button presses are done using pneumatics. The whole system is self-contained and doesn’t require a separate computer for processing. Our favorite part is that the controller remains completely unmodified and the industrial light tree used to indicate notes. The team says that the pneumatics aren’t quite fast enough to hit 100%, unlike some humans. Video of the bot in action after the break. Continue reading “Cythbot, Pneumatic Guitar Hero”
