Basics: How Do I Choose Appropriate Sensors?

Posted on 08 March, 2013

By Coleman Benson & filled under Industry, Where to Start.

For a robot to react to its environment, it must first obtain information about its surroundings. Robots are not limited to just sight, sound, touch, smell and taste. Robots can not only sense but give accurate values for a variety of environmental factors that humans are otherwise unaware of or incapable of doing.  Measure Distance [...]

Programming DAQs using FlowBotics Studio & FlowStone

Posted on 20 March, 2014

By Carl Owen & filled under Electronics, Software and Apps.

  In this tutorial we are going to cover Data Acquisition boards (or DAQ’s as they are better known) and how to program them using FlowBotics Studio which uses the FlowStone graphical programming language inside. Data acquisition devices form the basis of most robotics systems obtaining signals in and out of a system from external [...]

Robot Reverse Engineering: Designing an Autonomous Transatlantic Boat

Posted on 10 March, 2014

By Jeffrey Arcand & filled under Entertainment, Robotics Projects & Kits.

Some of you may have hear about Scout — The Autonomous Transatlantic Robot. She is a 12-foot long robotic solar-powered boat designed and built by 7 college/university students from the USA. She was launched in August 2013 from Rhode Island and programmed to autonomously cross the Atlantic Ocean to her destination in Spain. Although she [...]

This sensor seems to be what you are looking for: RB-Spa-679.

You could also use this digital readout: RB-Dfr-118

Finally, you could use a voltage or current sensor form this section along with an Arduino: http://www.robotshop.com/current-voltage-sensors.html

In that case, you cannot connect the receiver directly to the Arduino pins, you will need to create a circuit that will output an analogue voltage proportional to the amount of current passing trough the diode.

The resulting circuit will be very similar to this product: RB-Pol-49
