Actobotics Runt Rover™ Bogie Project – Part III

From: ServoCity


Actobotics Runt Rover™ Bogie

Development of The Bogie continues!


Now that we had power and RC capabilities, it was time to start bringing this little unit into a more robot- ic form. First, we added an Arduino UNO microcontroller from Robotshop.com, in preparation for the addition of microcontrolled RC capability as well as the addition of sensors and the basis for autonomy. Once the microcontroller was mounted we admit… we got sidetracked.

As one of the long term goals for many of the Editor’s Bench Projects is FPV with telemetry, we decided to fashion an FPV setup that would allow RC control from a remote location.

For this we used an Andoer HD 700TVL 1/3” CMOS NTSC 3.6mm MTV Board Lens Mini CCTV Security Video FPV Color Camera from Amazon. com. To get the signal from the camera/robot to the remote location we used a Boscam 32Ch 5.8G 600mw 5Km Wireless AV Transmitter with TS832 Receiver RC832 for FPV also from Amazon.com. This setup runs about $85. We used spare robot parts from our TETRIX MAX kit to make a base, a pedestal and a mount- ing bracket for the camera.

The test for the Bogie was to navigate the house, from a comfortable seat in the living room, while watching where the Bogie was going on the 55” TV! It is REALLY fun to see how good you can drive when you can’t see your robot.




Adding the camera brought up two issues: 1) Power supply and distribution and 2) designing the FPV setup to be interchangeable between different robots to avoid the $85 setup on each and every robot we build.

While the Bogie currently runs on a 7.2V NiMH battery, we had to borrow an 11.1V battery from another project to power only the camera in the short term. Streamlining this setup will mean moving to higher voltage LiPO batteries and using some sort of voltage regulation to provide proper power flow to each of the robot’s components.

As it happens, using the extra parts from the TETRIX MAX kit worked out great. The base unit we attached to the Bogie was a combination of 739077 Tube Clamp & 739074 80mm Tube while the camera bracket used a combination of 739077 Tube Clamp & 739065 32mm Channel. The hole pattern differ- ences between the Actobotics parts and the TETRIX parts was overcome by drilling 4 holes in the Bogie’s base which matched the TETRIX hole pattern and… Voila! Interchangeability.

Reader Input:

I will do my utmost to make progress on this project by next issue and report on what’s going on with it… the successes and failures. I sometimes learn more from a failure than from a success so let’s see how much of each we find. If something strikes you about this project… please email me at projects@botmag.com with what you think. I look forward to hearing from you!
