My daughters and I recently put together the Robotic Arm Tank, and everything went perfectly - build, wiring, programming. It drives, the gripper works really well, the arm goes up and down perfectly except when it tries to carry any weight over 85 grams. Once we hit 90 grams the arm wont raise. Any advice on how to increase the robot’s carrying capacity?
Robot arm seems a little weak- 85 grams max?

Hi Adam_Swift,
What’s kind of battery do you use?
Tt is suggested to use Alkaline battery with good quality like Energizer, DURACELL or rechargeable nickel-metal hydride or nickel-cadmium which can be bought from amazon or local shop.

Hi Adam_Swift,
How about trying the external power adapter (12V / 2A) or rechargeable Li-ion battery.
