A new EE Times
article offers the thoughts of Tsugio Makimoto on robot engineering.
Makimoto is a technical advisor to Sony Corp. He comments on the AIBO
and SDR-4X as well as some of the more interesting bits and pieces
insides such as a spherical three-axis acceleromter made by Ball
Semiconductor and a MEMs-based gyrometer from Analog Devices.
I recently was successful at building up a Gyro/Accelerometer combo PCB
using the MEMS chip ADXRS150 and the ADXLS202 Accelerometer. Both chips
are from Analog Devices. I've submitted a article about what i did to
DPRG which will hopefully be published later.
Anyway, the MEMS Rate Gyro chip works really nice and is easily
interfaced using a ADC (preferably a ADC in your MCU of choice). It
typically outputs a +/- 7mv per degree of Rate change, the faster the
change the higher the voltage change you get.
Don't know much about the robot, I noticed a number of websites that
have users upset with Sony's policies on what they are allowed to code
up for. So considering the price, it turned me off.
Maybe I don't want to do all that, but it would be nice if I could.
