Built from some COTS items, as well as custom-built items. The drive train needs to be re-worked as well as a lot of final work. The first pic is after assembly of some COTS parts mated with the custom drive train.
Everything currently has its own independent power source making the unit heavy and some what clunky.
Communication and control is via an Ethernet cross-over cable to my laptop running Parallels/Win7 and a custom-built VB.Net application that drives the rover. (Pictured)
Contents: - Custom-built (from COTS parts) twin-motor track chassis - ArduinoMEGA - 8 motor controllers - 2 color CCD board cameras (one at arm's end - not pictured) - RTC/temp/accelerometers/bump sensors/etc - Primary camera is mounted up high on pan-tilt mount with 4 10mm ultra-bright LEDs for illumination and also is surrounded with IR LEDs for use in dark locations -Primary camera has added laser pointer for 2nd camera coordinated viewing
V2 in progress
Rework will contain the following:
- Rock-crawler chassis w/ ESC (from RC car/truck)
- Updated roverOS
- Updated GROVER control application
- GPS location/logging to be added
- First attempt at autopilot
DFRobot MiniQ Motor Set
MiniQ motor, gearbox set, with wheels and tires
DFRobot Tank Upper Platform
Arduino MEGA 2560
Fabricated parts all made from Lexan
Wow, time flies when we have to worry about other things other than our hack projects!
Stay tuned... I am in the design phase of the next two generations of the rover. Gen2 suffered from some chassis-based mechanical issues. The new chassis platform will arrive tomorrow, so the modding can begin.
Gen 3 - ArduinoMEGA and Arduino UNO working in master/slave mode - Upgraded chassis based on R/C vehicle - More completely coded than Gen2
Gen 4 - Potential items of interest - Raspberry PI running the host OS, providing navigation, communication - Network of arduinos controlling sensors and drive functionality
