Education Robot Development Update

I would like to share the progress made over the past two months. We have completed most of the design work on the manipulators and finalized the main structure of the robot.

Grippers

After considering various options, we decided to stick with a parallel gripper design, as it is the lightest, easiest to produce, and capable of handling a variety of objects with different shapes.

Manipulators

1. We decided to use a semi-gantry, semi-serial design for the manipulator. Which allows us to maintain a balance between the required torque of the engines and the number of degrees of freedom.
2. For the motors, we chose the Feetech 3215 and Feetech 3250 servo motors, as they are lightweight, low-cost, and offer high torque along with magnetic encoders.
3. The length of the manipulator will be approximately 650 mm, and the estimated payload capacity is between 1.5 to 3 kg.

 

The current main characteristics of the robot are

– Movement type – similar to a Segway.
– Ability to lift manipulators to a height of up to 1400 mm.
– Payload capacity of each manipulator – 1500 g.
– Length of the manipulators – 650 mm.
– The chosen direction for the first version of the robot is an exploratory robot for schools, universities, and laboratories.

In May, I plan to publish a render of the concept of the future robot, which will closely reflect the future design.
