Flexbot design

Design overview hardware

Each "leg" of the flexbot consists of 4 actuators.

• An angled DC motor to control the wheel.
• Two linear actuators to control the motion of the robot's body.
• A linear actuator to adjust heading angle on the wheel.

Each of the legs are interfaced and controlled by μ-processor boards (Teensy 3.5). Each leg is split up in two parts which are presented as the ankle configuration and the knee configuration. The hardware design for robot's body is presented here.

A complete 3D model of the robot is available using the online CAD software Onshape.com - JCA should be contacted for sharing and editing the model.

Each leg part is connected with a two parallel stretches (mostly carbon tubes), each 4 carbon tubes, from foot to knee and from knee to hip (see also Flexbot 3D print).
