This year your participation was a success . The children were very impressed to be able to control a 30 pound robot using a mouse.  The robot was powered by a 10AH 24 volts battery , which drained after about 4 hours of continuous use . The robot was controlled using a Raspberry Pi , a Robogaia Relay Board and an old router.

We released 2 more products. Basically are the same product but one of them has a connector.
Those are mechanical encoder boards that can be used with the Arduino Encoder Shield

We pre launched a new project on prefundia.com  (link)

Robogaia IR RangeFinder








What it is?
The rangefinder is a tool that allows you to determine the distance to obstacles  and walls in order to avoid them. It is perfect in robotic applications where the robot needs to move and go to a determined position in unknown territory.



Product details

• detectable range: 200 mm to 1500 mm  (7 to 60 inches )
  
  
• 7.5 degrees angular resolution
  
  
• 2 scans per second
  
  
• 180 degrees view
  
  
• 1.5 meter radius
  
  
• easy readable output data in text format
  
  
• easy interface with other boards
  
  
• it comes pre calibrated
  
  

How It works

It has two Range sensors that are oriented at 90 degrees. This allows the unit to scan twice as fast as if it would have had only one sensor. The sensors scan 25 points, twice a second.

In the picture it shows the light beams for the two sensors at a determined time.

Maker Faire is coming to Cleveland this weekend(March 29, 2014 from 10am – 6 pm) . Link
We will be there with a big robot. Details to follow.
