Rover Update - It's been how long?
01/01/2016 at 21:41 • 0 commentsWow, 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 Gen2Gen 4 - Potential items of interest
- Raspberry PI running the host OS, providing navigation, communication
- Network of arduinos controlling sensors and drive functionality -

- Motors/Wheels built and mounted to chassis
- Chassis design finalized
- Manipulator arm installed
- Lexan mounting material installed so that platforms require less drilling and electronics can be removed
- Motor drivers installed
- Camera options finalized

v2 Changes
03/16/2014 at 16:29 • 0 comments- No more tether! The tether has been eliminated and current plans involve using Wifi for drive control (2.4GHz)
- Wireless video will be added to completely remove the need for tether
- Bump sensors removed
- Tracks removed / discarded for use on another project
- 4WD will be used instead of track drive
- Camera will no longer be mounted up high, but instead will be mounted on a pan/tilt unit up front
- 2nd CMOS camera removed
- DFRobot Arduino motor shield removed
- Individual DFRobot 1A motor controllers used for chassis drive
- Communications module of GROVER (control application) will be re-written from using RS-232 serial to TCP/IP

Chassis update 2
03/16/2014 at 16:00 • 0 commentsWow! What a difference 36 hours makes! The chassis is still being constructed with some helpful mechanical and electrical re-designs taking place.
- The chassis has been mated with the motors.
- New ArduinoMEGA sensor board, standoffs, and battery holders have been ordered.
- RN-XV WiFly Module has been ordered.
- Robotic arm has been modified to remove the power source and directly mount the arm on the ROV chassis.
