  • Dynamixel Sensor Module AX-S1
    Excellent product if you need to expand your robots senses
    Review by Ronald
    Ordered this product to give my robot more sensory capability after exhausting all 6 ports on my cm530. The fact that it chains to the servos yet is able to give my robot 3 more IR sensors is awesome
    Thumbs up

  • Analog pH Meter Kit
    Raspberry Pi - Needs Analog
    Review by Anthony
    Use the MCP3008 to get the device to work on the Raspberry Pi B. See pygrowtronics for details.

  • Analog pH Meter Kit
    Raspberry Pi - Needs Analog
    Review by Anthony
    This device is great. But to use it with the Raspberry Pi you'll need to use an Analog to Digital Converter. Luckily there is one out there that works (MCP3008). For details on how to get this working on the Raspberry Pi visit pygrowtronics.

  • Shock Sensor
    works ok, perhaps too sensitive
    Review by borgchick
    I connected this to one of the digital inputs of my Arduino, utilizing the the internal pull up resistor. After adding bounce detection, it works well enough.

    The only complaint is not enough of the sensitivity range is useful. The adjustment knob works fine. Except anything above a certain threshold, the thing is basically detecting shock ALL the time (even if there is the tiniest movement/vibration), making it quite useless for anything dealing with some movement. And on the low sensitivity end, a very small turn of adjustment knob seems to change the setting by a large amount.

    Oh, it is also not a small device as I thought. Measurements are approx: 4cm x 5cm x 2cm thick, weight is light, cable is about 1m long.

Basics: What Types of Mobile Robots are There?

Posted on March 07, 2012

By Coleman Benson & filled under Where to Start.

A custom robot design often starts with a “vision” of what the robot will look like and what it will do. The types of robots possible are unlimited, though the more popular are: Land-based wheeled robot Land-based tracked robot Land-based legged robot Air-based: plane, helicopter, blimp Water-based; boat, submarine Misc. and combination robot Stationary robot [...]

Basics: What is a Motor Controller?

Posted on February 20, 2012

By Coleman Benson & filled under Where to Start.

A Motor Controller is a device that acts as intermediary between your robot’s microcontroller, batteries and motors. A motor controller is necessary because a microcontroller can usually only provide roughly 0.1 Amps of current whereas most actuators (DC motors, DC gear motors, servo motors etc.) require several Amps. The current a motor consumes is related to [...]

Basics: How Do I Choose a Microcontroller?

Posted on February 20, 2012

By Coleman Benson & filled under Where to Start.

For a beginner, choosing the right microcontroller may seem like a daunting task, especially considering the range of products, specifications and potential applications. There are many different microcontroller boards available on the market: Arduino; BasicATOM; BasicX; Blueroomelectronics; POB Technology; Parallax. Pololu; Miscellaneous (Robotics Connection, New Micros, Rogue Robotics) and many more. Unless you plan to [...]

Basics: How Do I Choose Appropriate Sensors?

Posted on February 06, 2012

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 [...]

The below is found in the ssc-32 user's guide in the "Miscellaneous Register Commands" section. The "ver" command should return what you have. Using lynxterm, you can give a servo a slow movement command and then tell it to stop, and see if it stops. ...
