Cyborg Advances

The 'cyborg' robot currently under construction by webmaster Nicholas Lee has finally had it's mechanical construction completed. Each of the four limbs has all the degrees of freedom of a normal human limb. Three degrees of freedom at the shoulder and one at the elbow.

Without the drive electronics attached, the limb motors are completely relaxed. Thus, in the image below, the mechanical assembly has been placed on a box for support and its limbs posed in a 'crab' formation. The scale of the robot can be seen from the foot long ruler on the floor in font of it.

Overview of the robot, giving the a sense of scale.

'PIC' Robot Completed

This small wheeled robot was recently completed by webmaster Nicholas Lee. It uses a 4MHz PIC micro-controller with on-board flash memory to sample eight channels of analogue sensor data and to control two independent PWM driven DC gear motors. It is currently programmed to drive towards bright lights such as a torch light shining at it. The semicircular detector array of photocells can be seen on the left of the picture.
