Alpha Rex Walk – Solution
Disclaimer: I’ve had to factor in a rechargeable battery (which arrived late last week).
This means that the weight of the model is slightly forward of center. If you have an NXT with a battery pack, you’ll understand why it was necessary to make some changes.
I’ve had to mount the Intelligence Brick upside down (to allow for access to the recharge socket). The battery pack also adds a little extra size to the rear of the Brick, which means that it had to be mounted slightly forward of the original vertical brace, per this diagram:
So now the Intelligence Brick is mounted upside down. Makes it (ironically) easier to cable too. USB connections are still possible (due to the location of the USB port) but it’s recommended that you enable and use Bluetooth instead, if possible.
Apply these changes (mirrored) for the left leg to achieve the end result.
Give it a try for yourself :) Remember to mirror the design for the left foot.
Warning: I’ve not tried this on a Brick without the battery pack, so I can not guarantee the results.
I’ll be also posting notes taken from my experiences at getting a Windows computer to communicate with the NXT via Bluetooth – not an easy task. I’ve also managed to get the NXT to work with the Microsoft Robotics Studio 2008 which is in Beta/CTP (released April 2008). Check back for my notes on this.
