H40 Robotic Arm kit
Part #: BSL-GRIPKIT

This Robot Gripper with 2 x Robot Servos is used for the EMG-Controlled Robotic Arm created with BSL PRO Lesson Set H40 (10 labs).

  • The two Servo motors are used in tandem to perform “twist” and “grasp” movements to manipulate objects with the gripper.
  • The potentiometer is used to to optimize robotic control for each student’s unique EMG output. The potentiometer is easily accessed since the circuit board is separate from the motor.
  • The servos can control the gripper to open to 3.3 cm (1.3″) from closed and can rotate the gripper approximately 180 degrees. A Phillips screwdriver is required for assembly. It also includes two clamp cushions that adhere to the inner sides of the gripper.
  • Both motors use Pulse Width Control.
  • The output shaft is supported on the bottom and top with bronze bushings and the potentiometer is indirect drive.

BSL-GRIPKIT is included in BSLBME-ROBOT-HW, BSLBME-ROBOT-TA, and BSL-BME-ARM-TA.
