These are the parts for the sensor turret. We bought the servo and servo mounts, made the flat plate, and modified the multi-faced sensor plate.

Here we have soldered and mounted the Sonar Sensors into the plate.

In this pic we’ve mounted the sensor turret at the front of the partially assembled robot chassis, which is made out of machined 6061 aluminum.

Julajay solders the Arduino Nano microcontroller that will be Terrabot’s brain.

Julajay shows off her completed electronics subassembly for Terrabot, including the Arduino Nano, an Xbee Radio, a motor/servo controller, the power rail, the main power switch, and the high-capacity Lithium Polymer battery–All wired together into a nice electrical harness by Julajay. It is not ready for installation into the robot.

Here is a preliminary glimpse of the partially completed Terrabot, including the articulating chassis, two powerful brushless motors, two beefy steering servos for the 4WS, the core electronics, and the sensor head (visible on the left side). Next we will be adding the tires, a 9-DOF Inertial Measurement Unit (IMU) for “extreme” rough terrain assessment and a GPS for navigation.
