Hi, I’m new to this forum so forgive if the is old news.
I am using a dozen Lynx 6 robots in an academic setting. I have a been replacing the gripper servos at a frantic rate. The students will use the gripper for long periods causing them to overheat a burn out the H bridge transistors in the servos. I started out with plastic gear servos but they stripped the gears so I had to go to the metal gears. Is there any (simple) way to limit the current through these servos? I would be willing to build an external circuit for this purpose if it were not to complicated.
Thanks
You might try using diodes in series with the power to the servo motors to drop the motor voltage/current. The diodes would need to be in pairs such that current can flow both directions.
edit:
something to try first might be using a diode in series with the red power wire to the servo to get the voltage down to the usual low limit of ~4.8v to see if the servo h-bridge can survive at that lower voltage. If so, a “grippie” materal can be put in the gripper to help hold objects securely at the lower force.
