SRV-1 Blackfin Stereo Camera with pan/tilt and robot mount
Mounting the stereo camera on a pan/tilt assembly attached to a robot base proved to be quite simple. We are using the Lynxmotion BPT-KT pan/tilt head with a couple of extra holes for 1/2-inch hex standoffs. The BPT-KT is a nice stable unit with good HS-422 servos.
We use 1-inch standoffs with a couple of aluminum strips to attach the pan servo to the top of the SRV-1 robot base. The 1-inch x 2-inch mounting pattern for the standoffs is identical for the original SRV-1 base and the new SRV-1Q base.
The servos are driven directly from the stereo camera board using TMR6 and TMR7 of the left Blackfin and can be controlled directly via the 's' command in the control protocol with no modification to firmware. Only change from the original SRV-1 setup is longer motor and battery power wires.
