Makers can Design for NASA and Win Millions

at 10:45 pm. Filed under Crazy Hacks

 

Caleb Kraft interviewed Sam Ortega from NASA, Sam explains how the prize competitions at NASA work. Anyone can submit designs for their competitions but only US citizens can win the prize money.

“NASA Centennial Challenges were initiated in 2005 to directly engage the public in the process of advanced technology development. The program offers incentive prizes to generate revolutionary solutions to problems of interest to NASA and the nation. The program seeks innovations from diverse and non-traditional sources. Competitors are not supported by government funding and awards are only made to successful teams when the challenges are met.”

3D Print with Wood

3D Print with Wood

 

Most hobby 3D printers use melted plastic but it looks like we can now print using wood! It gets extruded at 200 degrees celsius. If I were to guess I would think it would be a material similar to MDF which is mainly sawdust and glue, of course the glue needs to be one that can be made soft again by reheating.

“A Thingiverse member going by the nom de printer “Kaipa” recently uploaded pictures of 3D-printed parts that weren’t made of extruded plastic, but a wood/plastic mixture he created on his own. The maker wouldn’t share the process for making the material, or even what the ingredients were, but he did offer to send sample spools of his experimental filament to interested hackers.”

Spray Chalk Machine

 

Wanting to make an impact on the sidewalk quickly? This Spray Chalk Machine is sure to get that done.

“This device is controlled by two Arduino Duemilanove boards, which apparently base the chalk “dot” timing on encoders sensing movement in the two wheels that the cart rides on. ”

 


ABB Robot made of LEGO

ABB Robot made of LEGO

 

Computer engineer Lassee Laussen and software engineer Ken Madsen built this ABB Robot made of LEGO bricks. It was an 8 month build to recreate the complex 6 axis machine. If you are interested in seeing some other interesting projects from Lassee and Ken have a look at Brick It.

“The LEGO version of the IRB 120 is so accurate that it mimics every shape and curve. It also has all 6 axes for the same freedom of movement that the real thing has. Sure, it won’t be moving as quickly as the original or carry the same payloads, but nonetheless it is a pretty spectacular recreation of an industrial robot that finds itself in assembly and pick-and-place operations in factories all over the world.”

at 7:48 am. Filed under Complex Hacks, Crazy Hacks, DIY Hacks

 

Sparkfun organized a day of Autonomous Vehicle fun at their Annual Autonomous Vehicle Competition.

Via: Hackaday

Ground Vehicle Classes

Each entrant will be classified by the judges as one of the following robot classes for their ground vehicle:

  • Micro/PBR – Less than $350 total spent, or small enough to fit into box that’s 10″x6″x4″
  • Doping Class – Bring the biggest, baddest and most expensive vehicle you can make ($1k+ or 25lbs+)
  • Non-Traditional Locomotion – Have a walker? A modified autonomous self-balancing pogostick, motorized hamster ball? This designation is for you.
  • Peloton – All remaining vehicles that don’t fit into any other class

 

Aerial Vehicle Classes

Your entry will fall into one of two categories for the aerial portion of the competition:

  • Fixed Wing – All traditional airplanes, or any vehicle with a fixed wing setup.
  • Rotating Wing – Quadcopters, helicopters, and other contraptions with rotating wings.”

Bipedal Walking Sentinel Project

Bipedal Walking Sentinel Project

 

This is a work in progress by Ye Guan, his Bipedal Walking Sentinel Project is a work in progress but the goal is challenging and Ye is making good strides towards a functional walking robot so far. What he is going for is a robot that looks something like the sentinel walker from Warhammer 40k and the two legged walker from Star Wars.

” The robot will have a complete compliment of sensors to help it understand its surrounding and its own condition. The current design uses a total of seven sensors.  For external obstacle avoidance there is a sonar sensor to detect long range surroundings, and an inferred distance sensor pointed down to detect the surface conditions for the robot’s next step. The sonar will allow the robot to detect and walk around large obstacles while the inferred sensor allows the robot to accommodate for changing road conditions, such as stairs. Two pressure sensors will be built into each foot to detect when the foot is on the ground. A gyroscope/accelerometer will be mounted in the head of the robot to inform the robot changes in its orientation and balance so it can adjust itself before falling. A photo detectors will tell the robot to turn on its head lights when there is a lack of ambient lighting. Finally temperature sensors will be added to make sure the system do not overheat, especially with the batteries and microcontrollers in such close proximity due to the space constraints. The entire system will be controlled through a Arduino Mega 2560 microcontroller mounted in the robot’s head.”

Electromagnetic Boots for Walking on the Ceiling

Electromagnetic Boots for Walking on the Ceiling

 

There will come a time when you have too much electronic junk laying about ready to take apart such that you can’t easily walk around. The obvious solution is to make some Electromagnetic Boots for Walking on the Ceiling.

Via:  Hackaday

“The magnet shoes themselves are easy to make and i can see people trying this. The tricky part is walking upside down, the ropes which have switches on to release the foot you need to step with also provide a way of reaching your leg back up because unlike walking normally your feet are trying to go over your head and not onto the surface in front of you. I tried to not have these but as soon as you release one foot you pivot?swing backwards on the fixed shoe as your centre of gravity shifts, once this has happened your other leg is no longer long enough to step back down so you have to pull you whole body weight up on the one leg which is VERY HARD.”
