Mini Dalek Gripper Arm

February 07, 2015

After a crazy few weeks and weekends working on a new software release at work, I finally have some time to play with my new 3D printer and get back to work on a hobby project I've taken on for my local maker space. We're putting together a Rube Goldberg machine and my section will be based around my mini Dalek robot. The plan is to have the Dalek receive a ping-pong ball from the previous section and then transport it to the next section and release it. It sounded so simple to start with but I've been struggling with figuring out how to attach the gripper arm and servo to the steel tube that I was using for the plunger arm.

This morning I had time to design a custom mount in Sketchup and then 3D print it. I made a mistake with aligning the mounting holes on one side but it's close enough and works really well. Here are some photos.
