Chip-E Magnetic Quick Disconnect Attachments System

Did you ever want to make different fancy gears for your Chip-E? I added quick disconnect 6 ports on original Chip-E robot: 2 dual ports on the shoulder, 1 dual port on the top, 1 single port in front and 2 single ports on the bottom of the feet.
There are various attachments I made so far:
ultrasonic sensor
IR sensor
Laser pointer
Turret
Shoulder joint
Electric Skateboard



And unlimited possibilities for the future servo-based or other kinds of attachments such as:
Gripper
Nerf launcher
Q-tip launcher/Crossbow
TTL controlled headlight
2 channel Remote Control receiver
Segway type balance board
Single leg electric skateboard
or any module that can be powered by 2s battery or 5v.
