What are Phidgets?

Small bits of hardware useful in robots
 Sensors
 Interface
 LCDs,
Boards
Servo control, Encoders, etc.

Varying complexity

Goal is to free the developer from dealing with
low-level hardware issues.

Made by Phidgets, Inc.
First Use

CoroWare needed an accelerometer for a robot.

We budgeted 3 days for integration.

We were done in 2-3 hours.

Most of our robots have an accelerometer in
them.
 Great
for a simple “bump” sensor or inclinometer
 Great
for force feedback joystick control
Interface Kits

We use the 8/8/8 Interface Kit.
 Digital
I/O
 Interface
with analog sensors

CoroWare’s big robot has humidity, light,
gripper pressure, and two voltage and
temperature sensors.

Digital I/O good for driving LEDs or
bump sensors.
Servo Control
 One
of our smaller robots uses a
compact 4-servo controller.
 Controls a 2 DoF Servo arm.
 We’ve also used
them to drive
Pan/Tilt units
for cameras.
A few others…

LCD
 16x2

LCD display with 16 Digital ins and outs.
Do it yourself sensors
 Sharp
 Line
GP2D12 IR sensors
following sensors
 Force
Sensing Resistors

4-port USB Hub

4-relay Interface Board
A Quick Tutorial…
Findings (The Good)

Very easy to integrate
 Lots
of OSes: Windows, Linux, Mac
 Lots
of languages: .NET, C/C++, Visual Basic

Great for prototyping or one-offs

Decent power economy

Easy to find power

Good support
Findings (The Slightly Less Good)

Some Power limitations

Reasonable cost

Need a CPU that supports Phidgets

Their biggest Servo controller
only handles 4 servos

Run out of USB ports quickly
