- There is a touch sensor located on each claw which provides input
on the claw's close / open.
- The claw will close when it hits the ladder step. It is designed to close
downwards.
- After over-coming the step, the claw will open to support the robot weight.
- Pic shows Monkey-bot in action. The robot is hanging on a gate-grill.
- At first, both claws are clutching the bottom step. The mobile left claw starts to move
upward while the right claw held the robot to the bottom step. Both claws are open.
- When the left claw hits the top step, the hinge on the claw closes. The sensor
sense the top step. The left claw proceeds until the sensor losts contact. This means
the claw has overcome the top step.
- To bring the remaining body up, the motor reverses causing the rack gear to move opposite.
With the left claw gripping & supporting the body at the top step,
the body is pull up together with the right claw.
