Edubot - Educational Robot for Kids

Motivation

The client wanted a mobile educational robot for kids with basic vision and gripping capabilities. The desired product was aimed for low cost and mass production.

Activity

We supported the client in all project stages.

Requirements/Concepts:

• defining relevant requirements,
• concept creation and
• final decision making.

Global system design: We found an optimal compromise between a low cost target and the number of features/complexity.

Mechanical design: A cost-effective articulated sheet metal base mechanism was combined with external body panels that allow for customization by kids.

Electronics design: A highly integrated, low-cost PCB(single sided, double layer) for motor control, sensor data collection and battery management has been developed to

• drive the 2-DoF gripper,
• drive and control the 2-DoF differential drive in a position feedback loop and
• collecting data from various interoceptive and exteroceptive sensors.
