The members of Shackspace got their hands on an antiquated robot arm. It’s a Mitsubishi Movemaster RM-101 as well as was most likely produced in the mid 1980’s. There’s practically nothing available that tells you exactly how to utilize the thing, as well as so they set out to figure out exactly how to manage the hardware.
This is a fantastic example of exactly how an EPROM dump can be truly useful. After even more inspection the team found that the arm is driven by a Z80 processor whose program is kept on an EPROM. The very first thing the men did was dump the memory because the aging storage will be useless if just a few bits ended up being degraded. This dump will be truly helpful for others whose chip has already provided up the ghost. The data from that dump was disassembled as well as painstakingly pawed with to figure out what commands were being sent to the arm. This method worked, as the team was able to re-implement the manage protocol as well as has already utilized the arm for some light painting as well as pen plotting (seen above). After the break you can see a manage demonstration.
