Using brushless drill motors

[robotic_ants]

While RC hobby technology has advanced and access to Asian manufactures has improved since 2017, the price of brushless motors in commercial products has so far commanded a premium price.

Its my opinion the cost of a brushless drill set up by time you've made modifications does not outweigh the simplicity in terms of maintenance and repair or the robustness of a simple gear drive or off the shelf planetary gearbox with a hobby motor.

With brushless drills your also paying for a battery technology usually Li-Ion which is not widely used in the hobby and heavier than LiPo's. Then onto the electronics again not something that can be used in a robot, usually these are fully potted and not as easy to interface with RC gear like an inexpensive and infinitely more programable VESC.

I feel we have advanced on from drill motors like we have moved on from windscreen wiper motors. A standard BRUSHED drill set-up is still a good way to get started and learn from for a really low cost but people that use them do generally move onto more tried and tested brushless setups using parts designed for robot combat.
