Recently we have designed a new Makeblock Gripper as the following picture shows.
For our previous one it can not seize the ball easy and other cube object tightly, and will not be useful after cut down the power. What more, the old Gripper is heavy. The new design has solved these problems.
We use the acrylic to build the gripper and to make it lighter. For the power, we use a tiny DC motor, so you can use Me-Motor Driver to drive the gripper. As following picture shows.
What’s more you can build the gripper with 2 claws or 4 claws as you like.
Connecting and controlling is easy, too. You can connect the gripper to Me-Base Shield or Me-Motor Driver, and use the motor driver to drive it as the following picture shows.
This is just a draft design, any suggestions?
Seriously, is there a way to shorten the shaft so it doesn’t protrude quite so far into the grip region?
