I require your help regarding the additional components needed for Agent 390 robot’s remote control.
Description:
Understand that Agent 390 with part n.o. RB-Sct-935 (https://www.robotshop.com/en/agent-390-tracked-robot-kit-motors.html) does not include the full list of accessaries; I myself compiled a component list based on my readings on robotshop website here and there,
RoboClaw 2x15A, 6-34VDC Regenerative Motor Controller, Product Code : RB-Bat-47
A suitable lipo battery charger (my search in robotshop online store didn't reach an item suitable)
Wondering if anyone can suggest whether the above component list is good enough for the purpose of remote control, and I am open to any advice for more suitable component.
About battery, wondering if under the same capacity, would a 4S Lipo pack be more suitable for Agent 390 compared to a 3S Lipo (e.g., low current) , as the motor controller supports 6-34VDC actually?
The included motors are rated at 6-12V, using a 4S battery (14.8V nominal and 16.8V fully charged) is fine but if the capacity is the same, the motors will only turn faster.
They will normally draw a little less current if the voltage is higher (thanks to ohm’s law) but it won’t make a big difference.
In other word, if you want your robot to move faster, take the 4S battery.
If you want it to run for a longer period of time, use a 3S with a higher capacity.
When the robot moves, the caterpillar tracks of the robot will gradually move to the sides and this will eventually cause friction with the boards that clamp the wheels. This makes the wheels stuck sometimes and results in a non-straight moving.
May I know what may cause the caterpillar tracks moving to the side and is there any way to maintain the caterpillar tracks at the middle of the wheels or any other possible solution to this problem?
